Introduction

GR3002 is a fully integrated power management IC designed for lithium battery charge and discharge management. It integrates lithium battery charging management, a synchronous boost converter, battery fuel gauge, and protection functional modules. The IC 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. The GR3002 features built-in power path management, supporting simultaneous charging and discharging, with integrated overcurrent and short-circuit protection.
