The SY6203 is a highly integrated 3A switch-mode battery charge management and system power path management device for single cell Li-Ion and Li-polymer batteries.
It integrates charge management, boost converter and protections.
The SY6203 can support up to 3A charging current with IR compensation.
The charging profile can be configured through I2C. The minimum step of charge voltage regulation is 10mV and the minimum step of charge current is 60mA.
SY6203 integrates an OTG function with 1.2A output capability, which can deliver power from the battery to other devices through a USB port.
SY6203 is compatible with the BC1.2 and can automatically set the input current limit based on the input sources.
The SY6203 is available in packages of 4mm*4mm QFN24 and 2.07mm*2.17mm CSP25 (0.4mm pitch).
