PRODUCTION DATA.
During boosting, when the battery voltage is above the battery over voltage threshold, VBATMAX, or below the minimum battery voltage threshold, VBATMIN, the IC turns off the PWM converter, resets OPA_MODE bit to 0, sets fault status bits and sends out fault pulse in STAT pin. Once the battery voltage goes above VBATMIN, the boost will start after the host sets OPA_MODE to “1” or OTG pin stays in active status.
