Description of the Principle
The HM4055 is a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries.
Constant-current/constant-voltage to charger batter by internal MOSFET .It can deliver up to 800mA of charge
current .No blocking diode or external current sense resistor is required. HM4055 include one Open-Drain charge
status Pin: Charge status indicator
CHRG
The internal thermal regulation circuit reduces the programmed charge current if the die temperature attempts to
rise above a preset value of approximately 145℃. This feature protects the HM4055 from excessive temperature,
and allows the user to push the limits of the power handling capability of a given circuit board without risk of
damaging the HM4055 or the external components. Another benefit of adopting thermal regulation is that charge
current can be set according to typical, not worst-case, ambient temperatures for a given application with the
assurance that the charger will automatically reduce the current in worst-case conditions.
The charge cycle begins when the voltage at the VCC pin rises above the UVLO level, a current set resistor is
connected from the PROG pin to ground. TheCHRG pin outputs a logic low to indicate that the charge cycle is on
going. At the beginning of the charge cycle, if the battery voltage is below 2.9V, the charge is in precharge mode to
bring the cell voltage up to a safe level for charging. The charger goes into the fast charge constant-current mode
once the voltage on the BAT pin rises above 2.9 V. In constant current mode, the charge current is set by RPROG
.
When the battery approaches the regulation voltage 4.2V, the charge current begins to decrease as the HM4055
enters the constant-voltage mode. When the current drops to charge termination threshold, the charge cycle is
terminated, andCHRG
pin assumes a high impedance state to indicate that the charge cycle is terminated . The
charge termination threshold is 10% of the current in constant current mode. To restart the charge cycle, remove the
input voltage and reapply it . The charge cycle can also be automatically restarted if the BAT pin voltage falls below
the recharge threshold. The on-chip reference voltage, error amplifier and the resistor divider provide regulation
voltage with 1% accuracy which can meet the requirement of lithium-ion and lithium polymer batteries. When the
input voltage is not present, or input voltage is below VBAT, the charger goes into a sleep mode, dropping battery
drain current to less than 2μA. This greatly reduces the current drain on the battery and increases the standby time.
The charging profile is shown in the following figure:

The charge current is programmed using a single resistor from the PROG pin to ground. The program resistor
and the charge current are calculated using the following equations.:

a. K is the coefficient of variation, It generally is 1, but due to the vary operating environment, K is varied in the
range: 0.8~1.4
b. The up form is just for reference, it will varied ±10% according to the heat dissipation of the using PCB board;
c. The footprint copper pads should be as wide as possible and expand out to larger copper areas to spread and
dissipate the heat to the surrounding ambient.
Charge termination
A charge cycle is terminated when the charge current falls to 1/10th the programmed value after the final float
voltage is reached. This condition is detected by using an internal filtered comparator to monitor the PROG pin.
When the PROG pin voltage falls below 100mV for longer than tTEMP (typically 1.8mS), Charging is terminated. The
charge current is latched off and the HM4055-N enters standby mode, where the input supply current drops to 55μA
Page 9
HM4055A
(Note:C/10 termination is disabled in trickle charging and thermal limiting modes).
When charging, transient loads on the BAT pin can cause the PROG pin to fall below 100mV for short periods
of time before the DC charge current has dropped to 1/10th the programmed value. The 1.8mS filter time (tTEMP) on
the termination comparator ensures that transient loads of this nature do not result in premature charge cycle
termination. Once the average charge current drops below 1/10th the programmed value, the HM4055 terminated
the charge cycle and ceases to provide any current through the BAT pin. In this state all loads on the BAT pin must
be supplied by the battery.
The HM4055 constantly monitors the BAT pin voltage in standby mode. If this voltage drops below the 4.02V
recharge threshold (VRECHRG ),another charge cycle begins and current is once again supplied to the battery. To
manually restart a charge cycle when in standby mode, the input voltage must be removed and reapplied or the
charger must be shut down and restarted using the PROG pin. Figure 1 shows the state diagram of a typical charge
cycle.
Charge Status Indicator (CHRG)
HM4055 has one open-drain status indicator output CHRG.
CHRG is pull-down when the HM4055 in a
charge cycle. In other statusCHRG in high impedance.
Represent in failure state, when the charger with no battery: LED don’t light. If battery is not connected to
charger,CHRG pin outputs a PWM level to indicate no battery. If BAT pin connects a 10μF capacitor, the frequency
ofCHRG flicker about 1-4S, If not use status indicator should set status indicator output connected to GND.
Thermal limiting
An internal thermal feedback loop reduces the programmed charge current if the die temperature attempts to
rise above a preset value of approximately 110℃ . The feature protects the HM4055 from excessive temperature
and allows the user to push the limits of the power handling capability of a given circuit board without risk of
damaging the HM4055. The charge current can be set according to typical (not worst-case) ambient temperature
with the assurance that the charger will automatically reduce the current in worst-case conditions.
Under Voltage lockout (UVLO)
An internal under voltage lockout circuit monitors the input voltage and keeps the charger in shutdown mode
until VCC rises above the under voltage lockout threshold . If the UVLO comparator is tripped, the charger will not
come out of shutdown mode until VCC rises 140mV above the battery voltage.
Manual terminate
At any time of the cycle of charging will put the HM4055 into disable mode to remove RPROG(PROG pin is
float). This made the battery drain current to less than 2μA and reducing the supply current to 55μA. To restart the
charge cycle, connect a programming resistor.
If HM4055 in the under voltage Lockout mode, the CHRG is in high impedance state, or VCC is above BAT
pin 140mV, or VCC is too low.
Auto restart
Once charge is been terminated, HM4055 immediately use a 1.8ms filter time ( t
)on the
RECHARGE

termination comparator to constant monitor the voltage on BAT pin. If this voltage drops below the 4.02V recharge
threshold (about between 80% and 90% of VCC), another charge cycle begins. This ensured the battery maintained
(or approach) to a charge full status and avoid the requirement of restarting the periodic charging cycle. In the

Stability Considerations
In constant-current mode, the PROG pin is in the feedback loop, not the battery. The constant-current mode
stability is affected by the impedance at the PROG pin. With no additional capacitance on the PROG pin, the charger
is stable with program resistor values as high as 20KΩ. However, additional capacitance on this node reduces the
maximum allowed program resistor. Therefore, if IPROG pin is loaded with a capacitance C, the following equation
should be used to calculate the maximum resistance value for RPROG
:

As user, may think charge current is important, not instantaneous current. For example, to run a low current
mode switch power which parallel connected with battery, the average current from BAT pin usually importance to
instantaneous current. In this case, In order to measure average charge current or isolate capacitive load from IPROG
pin, a simple RC filter can be used on PROG pin as shown in Figure 2. In order to ensure the stability add a 10KΩ
resistor between PROG pin and filter capacitor.
Power dissipation
The conditions that cause the HM4055 to reduce charge current through thermal feedback can be
approximated by considering the power dissipated in the IC. Nearly all of this power dissipation is generated by the
internal MOSFET-this is calculated to be approximately:
PD (VCC VBAT ) X I BAT
The approximate ambient temperature at which the thermal feedback begins to protect the IC is:
TA 110C PDJA ; TA 110C (VCC VBAT ) X IBAT X JA
For example: The HM4055 with 5V supply voltage through programmable provides full limiting current 800mA
to a charge lithium-ion battery with 3.75V voltage
JA is 150℃/W ( reference to PCB layout considerations), When
HM4055 begins to decrease the charge current, the ambient temperature about:
TA 110C (5V3.75V ) X (800mA) χ150C / W
TA 110C
X 150C / W 110C 75C TA =35C
HM4055 can work in the condition of the temperature is above 35℃, but the charge current will pull down to
below 800mA. In a fixed ambient temperature, the charge current is calculated to be approximately :
110℃- TA
(VCC- VBAT )*θJA
IBAT
=
Just as Description of the Principle part talks about so, the current on PROG pin will reduce in proportion to the
reduced charge current through thermal feedback. In HM4055 design applications don’t need to considerate the
worst case of thermal condition, this point is importance, because if the junction temperature up to 110℃ ,IC will auto
reduce the power dissipation.
Thermal considerations
Because of the small size of the thin SOT23-5 package, it is important to use a good thermal PC board layout to
maximize the available charge current. The thermal path for the heat generated by the IC is from the die to the
copper lead frame, through the package leads, (especially the ground lead) to the PC board copper. The PC board
copper is the heat sink. The footprint copper pads should be as wide as possible and expand out to larger copper
areas to spread and dissipate the heat to the surrounding ambient. Other heat sources on the board, not related to
the charger, must also be considered when designing a PC board layout because they will affect overall temperature
rise and the maximum charge current.
Add thermal regulation current
It will effective to decrease the power dissipation through reduce the voltage of both ends of the inner MOSFET.
Page 12
HM4055A
In the thermal regulation, this action of transporting current to battery will raise. One of the measure is through an
external component(as a resistor or diode) to consume some power dissipation.
For example: The HM4055 with 5V supply voltage through programmable provides full limiting current 800mA
to a charge lithium-ion battery with 3.75V voltage. If JA is 105℃/W, so that at 25℃ ambient temperature, the charge
current is calculated to be approximately :
110℃-25℃
(Vs-IBAT *Rcc - VBAT )*θJA
IBAT
=
In order to increase the thermal regulation charge current, can decrease the power dissipation of the IC through
reducing the voltage (as show fig.3) of both two ends of the resistor which connecting in series with a 5V AC adapter.
With square equation to calculate IBAT
:
4Rcc(110℃- TA )
(Vs- VBAT )- (Vs- VBAT )2 -

=
If RCC=0.25Ω, VS=5V, VBAT=3.75V, TA=25℃ and JA =105℃/W, we can calculate the thermal regulation charge
current: IBAT=764mA. It means that in this structure it can output 800mA full limiting charge current at more high
ambient temperature environment.
Although it can transport more energy and reduce the charge time in this application, but actually spread charge
time, if HM4055 stay in under-voltage state, when VCC becomes too low in voltage mode. Fig.4 shows how the
voltage reduced with increase RCC value in this circuit. This technique will act the best function when in order to
maintain the minimize the dimension of the components and avoid voltage decreased to minimize RCC
.

VCC bypass capacitor
Many types of capacitors can be used for input bypassing, however, caution must be exercised when using
multilayer ceramic capacitors. Because of the self-resonant and high Q characteristics of some types of ceramic
capacitors, high voltage transients can be generated under some start-up conditions, such as connecting the charger
input to a live power source. Adding a 1.5Ω resistor in series with a ceramic capacitor will minimize start-up voltage

transients.
Charging Current Soft Start
HM4055 includes a soft start circuit which used to maximize to reduce the surge current in the begging of
charge cycle. When restart a new charge cycle, the charging current ramps up from 0 to the full charging current
within 20μs. In the start process it can maximize to reduce the action which caused by surge current load.
USB and Wall Adapter Power
HM4055 allows charging from a USB port, a wall adapter can also be used to charge Li-Ion/Li-polymer
batteries. Figure 5 shows an example of how to combine wall adapter and USB power inputs. A P-channel MOSFET,
M1, is used to prevent back conducting into the USB port when a wall adapter is present and Schottky diode, D1, is
used to prevent USB power loss through the 1KΩ pull-down resistor.
Fig.5:Combining Wall Adapter and USB Power
Generally, AC adaptor is able to provide bigger much current than the value of specific current limiting which is
500mA for USB port. So can rise charge current to 600mA with using a N-MOSFET (MN1) and an additional set
resistor value as high as 10KΩ.
Board Layout Considerations
RPROG at PROG pin should be as close to HM4055 as possible, also the parasitic capacitance at PROG pin
should be kept as small as possible.
The capacitance at VCC pin and BAT pin should be as close to HM4055 as possible.
It is very important to use a good thermal PC board layout to maximize charging current. The thermal path for
the heat generated by the IC is from the die to the copper lead frame through the package lead (especially the
ground lead) to the PC board copper, the PC board copper is the heat sink. The footprint copper pads should be
as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the surrounding
ambient. Feed through vias to inner or backside copper layers are also useful in improving the overall thermal
performance of the charger. Other heat sources on the board, not related to the charger, must also be
considered when designing a PC board layout because they will affect overall temperature rise and the
maximum charge current.
The ability to deliver maximum charge current under all conditions require that the exposed metal pad on the
back side of the HM4055 package be soldered to the PC board ground. Failure to make the thermal contact
between the exposed pad on the backside of the package and the copper board will result in larger thermal
resistance.
