Introduction

AI Translation

This IC is a fully integrated power management chip designed for lithium battery charge and discharge management, integrating lithium battery charging management, synchronous boost converter, battery fuel gauge, and protection function modules. It supports automatic load detection and light-load auto-shutdown, with a standby current of only 7μA after auto-shutdown. The charging current is 0.7A, and the synchronous boost output current is 0.8A. It features built-in power path management supporting simultaneous charge and discharge, with integrated overcurrent and short-circuit protection.
