SY6103 Sample Application
General Description

The SY6103 is a 500mA, highly integrated single cell linear battery charger IC with power path management for wearable and IoT devices using Li-ion/Li-Polymer batteries. The I2C serial interface with charging and system setting can be allowed to be controlled flexibly.
The SY6103 can automatically complete charger phase include pre-charge, fast charge, charge termination. Also monitor battery temperature during charging. Power path management will provide higher priority system load even with depleted battery. 
The device owns full system reset, include watchdog and PWRKEY reset, also supports ship mode to save power consumption.
The SY6103 is available in a 1.725m x 1.725m, 9-ball/0.5-pitch CSP package.
