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 temperature and turns the MOSFET off when the chip temperature exceeds.
