Introduction

AI Translation

LY6294 is a fully integrated power management IC designed for Bluetooth charging cases, incorporating lithium battery charge management, a synchronous boost converter, battery fuel gauge, and protection function modules. The chip supports two modes: auto load detection with auto shutdown, and constant 5V output. In auto shutdown mode, the standby current is 4uA; in constant 5V output mode, the standby current is 45uA.
