HM5030

HM5030 Series-High input Voltage Linear Li-Ion Battery Charger

GENERAL DESCRIPTION

FEATURES

The HM5030 Series is a complete constant

current & constant voltage linear charger for

single cell lithium-ion batteries. Its SOT23-5

package and low external component counts

make the HM5030 Series ideally suited for

portable applications. Furthermore, the HM5030

Series is specifically designed to work within USB

power specifications.

30V standoff input voltage at VCC pin

Programmable Charge Current Up to 600mA

No MOSFET, Sense Resistor or Blocking Diode

Required

Complete Linear Charger in SOT23-5 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 HM5030 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 HM5030 automatically

enters a low current state, dropping the battery

drain current to less than 2uA. The HM5030 can

be put into shutdown mode, reducing the supply

current to 50uA.

Under-voltage lockout, automatic recharge and

two status pins to indicate charge and charge

termination.

PIN FUNCTION

CHRG (PIN 1):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.

GND (PIN 2): Ground.

BAT (PIN 3): 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.

VCC (PIN 4): Positive Input Supply Voltage.

Provides power to the charger, VCC can range from 4.25V to 6.5V and should be bypassed with at least a 10uF

capacitor. When VCC drops to within 30mV of the BAT pin voltage, the HM5030 enters shutdown mode,

dropping IBAT to less than 2uA.

PROG (PIN 5):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.

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 to 10% 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 HM5030 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

CHARGE STATUS INDICATION

The CHRG 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.

BAT Pin C=10uF and Battery unavailable

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).
