• SC6341

  A device supporting switching frequencies up to 2MHz, designed for power-management needs in ultra-compact applications. It contains two independent loop-regulated and protected buck DC/DC converter channels, with programmable phase configuration options including 1+0, 2+0, 3+0, 4+0, 1+1, 2+1, 3+1 and 2+2, and supports an I2C-compatible serial interface for fault telemetry and user-customized configuration.

• SC8911

  A synchronous buck-boost charger supporting buck mode, boost mode and buck-boost mode during forward charging or reverse discharging. It manages charging of 2-cell lithium-ion and lithium iron phosphate batteries with trickle charge, pre-charge, constant current, constant voltage and automatic termination, and supports a wide 3.3V to 21V discharge output range. Via an I2C interface, users can set charge/discharge modes and program charge current, charge voltage, input voltage regulation, input current limit, OTG output voltage regulation, current limit and other parameters. It provides monitoring of input current/voltage, battery current/voltage, junction temperature and output current of 3 ports, and comprehensive protections including port and battery over-voltage, output over-voltage, battery and output under-voltage, cycle-by-cycle current limit and thermal shutdown. It is packaged in a 4mm x 5mm QFN-27.
