RT9718 Over Voltage Protection IC

The RT9718 is an integrated circuit optimized to protect low voltage system from abnormal high input voltage (up to 28V). The IC monitors the input voltage, battery voltage and the charging current to make sure all three parameters are operated in normal range. When the input voltage exceeds a certain OVP threshold voltage level, the IC will turn off the pow.
