Overview
LY6394 is a fully integrated power management IC designed for Bluetooth earphone charging cases. The chip integrates lithium battery charging management, a synchronous boost converter, battery gauge, and protection function modules. It supports automatic load detection with auto-shutdown mode and 5V always-on output mode. In auto-shutdown mode, the default standby voltage is 2V; by connecting a pull-up resistor from the BAT pin to the OUT pin, the standby voltage can be set to the battery voltage. The standby current in auto-shutdown mode is 4.5uA, while the chip standby current in 5V always-on output mode is 45uA.
Applications
- Bluetooth earphone charging case
- Power bank
- Portable lithium battery applications
