6.3.5 Output Discharge Function

To make sure the device starts up under the defined conditions, the output discharges through the VOS pin with a typical discharge resistor of 200 Ω whenever the device shuts down. This discharge happens when the device is disabled or if thermal shutdown, undervoltage lockout or short-circuit hiccup mode is triggered.
