HM5031DR
HM5031DR Series- High input Voltage Linear Li-Ion Battery Charger
GENERAL DESCRIPTION
FEATURES
The HM5031DR Series is a complete constant
current & constant voltage linear charger for
single cell lithium-ion batteries. Its DFN package
and low external component counts make the
HM5031DR Series ideally suited for portable
applications. Furthermore, the HM5031DR Series is
specifically designed to work within USB power
specifications.
30V standoff input voltage at VCC pin
Programmable Charge Current Up to 1000mA
No MOSFET, Sense Resistor or Blocking Diode
Required
Complete Linear Charger in DFN Package for
single Cell Lithium-Ion Batteries
Charges Single Cell Li-Ion Batteries Directly from
USB Port
No external sense resistor is needed, and no
blocking diode is required due to the internal
MOSFET architecture. The charge voltage is fixed
at 4.2V/4.3V/4.35V/4.4V, and the charge current
can be programmed externally with a single
resistor. The HM5031DR Series automatically
terminates the charge cycle when the charge
current drops to 1/10 the programmed value after
the final float voltage is reached.
When the input supply (wall adapter or USB
supply) is removed, the HM5031DR Series
automatically enters a low current state, dropping
the battery drain current to less than 2uA. The
HM5031DR Series can be put into shutdown mode,
reducing the supply current to 50uA.

PIN FUNCTION
VCC (PIN 1): Positive Input Supply Voltage.
STDBY (PIN 2): The completion of battery charging instructions side.
When the battery charge is complete, STDBY pulled low by internal switches, indicating the completion of
charging. In addition, STDBY pin will be in a high-impedance state.
CHRG (PIN 3): Open-Drain Charge Status Output.
When the battery is charging, the CHRG pin is pulled low by an internal N-channel MOSFET. When the charge
cycle is completed, CHRG pin will be in a high-impedance state.
CE (PIN 4): Chip enable input.
HM5031DRX High Enable,HM5031DRXN connect “NC”.
CE pin can be TTL or CMOS level-level driver.
CE pin is low voltage tolerance pin and can’t connect with VCC directly.
GND (PIN 5): Ground.
NC (PIN 6): No Connection.
PROG (PIN 7): Charge Current Program, Charge Current Monitor and Shutdown Pin.
The charge current is programmed by connecting a 1% resistor, RPROG, to ground. When charging in
constant-current mode, this pin servos to 1V. In all modes, the voltage on this pin can be used to measure the
charge current using the following formula:
IBAT = (VPROG/RPROG) x950.
The PROG pin can also be used to shut down the charger. Disconnecting the program resistor from ground
allows a compensated current to pull the PROG pin high. When it reaches the 1.21V shutdown threshold
voltage, the charger enters shutdown mode, charging stops and the input supply current drops to 50uA.
Reconnecting RPROG to ground will return the charger to normal operation.
BAT (PIN 8): Charge Current Output.
Provides charge current to the battery and regulates the final float voltage to 4.2V/4.3V/4.35V/4.4V. An internal
precision resistor divider from this pin sets the float voltage which is disconnected in shutdown mode.

OPERATION
CHARGE CYCLE OVERVIEW
When a battery charge cycle begins, the battery charger first determines if the battery is deeply discharged. If
the battery voltage is below Vtrikl, typically 2.9V, an automatic trickle charge feature sets the battery charge
current to10% of the full-scale value.
Once the battery voltage is above 2.9V, the battery charger begins charging in constant-current mode. When the
battery voltage approaches the 4.2V/4.3V/4.35V/4.4V required to maintain a full charge, otherwise known as the
float voltage, the charge current begins to decrease as the HM5031DR Series switches into constant-voltage mode.
TRICKLE CHARGE AND CHARGE TERMINATION
Any time the battery voltage is below Vtrikl, the charger goes into trickle charge mode and reduces the charge
current to 10% of the full-scale current. If for any reason the battery voltage rises above Vtrikl , the charger will
resume charging. When the battery is charging, the CHRG pin is pulled low by an internal N-channel MOSFET.
When the charge cycle is completed, CHRG pin will be in a high-impedance state.
When the battery voltage reach the regulated charge voltage, typically 4.2V/4.3V/4.35V/4.4V and the charger
current is below 10% of fast charge setting current, charging of the battery will discontinue and no more current
will be delivered.
At this time, STDBY pulled low by internal switches, indicating the completion of charging. In addition, STDBY
pin will be in a high-impedance state
CHARGE STATUS INDICATION
The CHRG pin and the STDBY pin indicates the status of the battery charger..Four possible states are
represented by charging, complete, fault, floating
Table 1 illustrates the four possible states of them when the battery charger is active.

AUTOMATIC RECHARGE
After the battery charger terminates, it will remain off, drawing only microamperes of current from the battery.
If the portable product remains in this state long enough, the battery will eventually self discharge. To ensure
that the battery is always topped off, a charge cycle will automatically begin when the battery voltage falls below
VRECHRG(typically 4.08V).
SHUT DOWN
When the Voltage of CE pin is disable,HM5031DR SERIES will shut down. the shut down current will below 2.5uA.
