SY6201 is a low-power and high-precision switch charger of NVDC architecture. It integrates charge, boost converter and protections, optimized for fast charging applications of small capacity lithium-ion batteries, charging current up to 2A and termination current down to 10mA. The standby current is less than 13uA and ship mode current is less than 3uA.
The charging profile can be configured by I2C. The minimum step of charge voltage regulation is 10mV and the step of charge current is 20mA. Safety features are including JEITA profile, safety timer, and over-voltage/over-current/ under-voltage protection. The boost converter output maximum current 1.2A. The quiescent current of boost mode is less than 500uA and it also has high efficiency at light load.
SY6201 package is QFN16-4 mm * 4 mm.
