ETA4662

I²C Communication, 500mA Single Cell Li-Ion Battery Charger with Power

Path Management，1mA Termination and <1uA Battery Leakage

DESCRIPTION

FEATURES

The ETA4662 is a single cell battery charger with power

path management function for Li-Ion and Li-Polymer battery.

It features pre-charging, fast charging (CC) and constant

voltage (CV) charging, end-of charging termination, and

auto-recharge, and built-in safe-timer preventing from being

over-charged or host running out of control.



Fully Autonomous Charger for Single Cell Li-Ion and

Li-Polymer Battery

21V Maximum Input Voltage Rating with Over-

Voltage Protection

I²C Interface for Setting Charging Parameters and

Status Reporting

The power path management function features a low

dropout regulator from the input to the system and a low

R_DSONswitch from battery to the system, so it separates the

charging current from the system load. This function

prioritizes the battery and the system, ensuring the

continuous power supply to the system.

Fully Integrated Power Switch and No External

Blocking Diode Required

Battery Temperature Monitor and Programmable

Timer



Battery or PCB Over-Temperature Protection

System Reset Function

Parameters and functions are programmed or selected

through an I²C compatible serial interface, such as input

current limit, charging current, battery regulation voltage,

safety timer, battery UVLO. It also features a safe watchdog

protection.

Battery Disconnection Function

Thermal Limiting Regulation on Chip
