Front-end Protection IC for battery powered applications

RT9718 is fully integrated circuit designed to provide protection to Li-ion batteries powered applications from up to 28V abnormal high input voltage.

RT9718 monitors the input voltage, battery voltage and the charging current. In case of an input over-voltage condition, RT9718 will turn off the power MOSFET within 1μs to remove the power before any damage occurs. Additionally, RT9718 can provide a voltage output without the existence of battery.
