Introduction

AI Translation

This product is a fully integrated power management IC for Bluetooth charging cases, incorporating lithium battery charging management, a synchronous boost converter, battery fuel gauge, and protection function modules. It supports direct Hall sensor drive control of the enable pin, enabling automatic headphone reconnection on case open, 8-second LED illumination on case open, and automatic boost activation on case close — all without external MOSFETs, transistors, or other output loop control circuits. The IC also supports MCU control of the enable pin for fast output on/off switching to facilitate communication between the charging case and earphones, eliminating the need for external control MOSFETs and current discharge MOSFETs.
