ETA4662
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.
The power path management function features a low dropout regulator from the input to the system and a low RDSON switch 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.
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.
The ETA4662 is available in FCQFN-9L package.
