PRODUCTION DATA
The falling edge of the SNS pin below VIL,SNS is considered a fault case and causes the load switch to be disabled for tRESTART (typically 2 ms). After the tRESTART time, the switch is automatically re-enabled as long as EN is still above VIH,EN. In the case, the SNS pin is being used to monitor VOUT or a downstream voltage. The restart helps to protect against excessive overcurrent if there is a quick short to GND. See Figure 9-3.
