SC8913

SC8913 is a synchronous buck charger converter with reverse boost discharging function. It integrates power MOSFETs and supports very wide input and output voltage range, suitable for applications of 1 to 4-cell Li-ion battery. In charging mode, it steps down the input voltage and effectively charging the batteries as long as the input voltage is higher than battery voltage. SC8913 supports trickle charging, constant current (CC) charging and constant voltage (CV) charging management functions automatically. In discharging mode (reverse boost mode), SC8913 is able to output a boosted voltage up to 26V effectively. The SC8913 features I2C interface, so the user can easily set the charging/discharging mode and program the input current limit, output current limit and output voltage through I2C. It also supports DP/DM handshaking, the adapter insert detection function, load insert detection function, small current detection. Meantime, it offers a PMOS gate driver for external power path control, an open drain output for general purpose, and also a 10-bit ADC resource. The user can control all these functions through I2C. All these features help simplify the system design and reduce the BOM. The SC8913 supports under voltage lockout, over voltage protection, over current protection, short circuit warning and over temperature protections to ensure safety under different abnormal conditions. SC8913 adopts 40 pin QFN 6x6 package.
