PRODUCTION DATA.
The IC provides a built-in input overvoltage protection to protect the device and other components against damage if the input voltage (Voltage from VBUS to PGND) goes too high. When an input overvoltage condition is detected, the IC turns off the PWM converter, sets fault status bits, and sends out a fault pulse from the STAT pin. Once VBUS drops below the input overvoltage exit threshold, the fault is cleared and charge process resumes.
