RT9718 Datasheet | Richtek

Overvoltage Protection IC 1 General Description The RT9718 is an integrated circuit optimized to protect low voltage system from abnormally high input voltages (up to 30V). The IC monitors the input voltage, battery voltage, and charging current to ensure all three parameters operate within the normal range. When the input voltage exceeds a certain Overvoltage Protection (OVP) threshold voltage level, the IC will turn off the power MOSFET within 1s to remove the power before any damage occurs. The RT9718 can also provide a voltage output in the absence of battery. The current in the power MOSFET is limited to prevent the battery from being charged with excessive current. The...
