Introduction

AI Translation

LY6369 is a fully integrated power management IC designed for Bluetooth earphone charging cases. It integrates lithium battery charge management, a synchronous boost converter, battery fuel gauge, and protection functions. The chip adopts a proprietary boost control circuit architecture that fully supports PCB trace inductors, significantly reducing solution size and cost. The charge current is programmable via an external resistor on the ISET pin, with a setting range of 180mA ~ 450mA and a maximum discharge current of 600mA. The chip supports direct MCU readout of charge, full-charge, discharge, and standby status information.
