Introduction

AI Translation

A dedicated chip for lithium battery charge and discharge management. During charging, it supports 3.7V lithium battery charging with a maximum configurable current of 1A. During discharging, it employs a synchronous buck converter operating at a switching frequency of 1MHz, delivering a discharge current of up to 3A. Integrated protections include under-voltage protection, short-circuit protection, and over-temperature protection. Built-in status indication for charging, charge complete, and short-circuit states. The NTC pin enables real-time battery temperature monitoring for safe operation. Quiescent current is only 6uA under no-load conditions.
