RT9709 Datasheet (RichTek) - Integrated Over Voltage Protection Circuit

RT9709, Integrated Over Voltage Protection Circuit

The RT9709 is an integrated circuit (IC) optimized to protect low voltage system from abnormal high voltage input 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.

It also monitors its own temperatur
