Introduction

AI Translation

This chip is a fully integrated power management IC designed for Bluetooth charging cases, integrating lithium battery charge management, a synchronous boost converter, battery fuel gauge, and protection function modules. It supports Hall sensor direct drive of the enable pin, enabling automatic earphone reconnection on lid open, LED illumination for 8 seconds on lid open, and automatic boost activation on lid close — eliminating the need for external MOSFETs, transistors, and other output loop control circuits. It also supports MCU control of the enable pin for fast output turn-on and turn-off, enabling communication between the charging case and earphones without external control MOSFETs or current discharge MOSFETs. An integrated NTC temperature protection function allows a single NTC resistor to monitor lithium battery temperature during both charging and discharging states.
