For the first pre-production samples, the ENA pin sequence must follow the recommendations below to allow the device to operate within the safe operating region.

Case A: After VIN has been applied and V_(ENA) > V_{EN_IR}: Never set V_(ENA) < V_{EN_IF} with V_(VIN) > V_{VIN_UVLOP_FALLING}.

Case B: To reset a fault condition detected by the module that resulted in /PG = high, while keeping V(ENA) > V_{EN_IR}:

1. Set V_(VIN) = 0 V
2. Wait until the (VDD – VEE) and (COM – VEE) rails are discharged
3. Set V_(VIN) > V_{VIN_UVLOP_RISING}

Case C: To power-down and power-up, use this ENA triggered power-up sequence:

1. Set V_(VIN) = 0 V while keeping V(ENA) > V_{EN_IR}
2. Wait until the (VDD – VEE) and (COM – VEE) rails are discharged
3. Set V_(ENA) = 0 V
4. Set V_(VIN) > V_{VIN_UVLOP_RISING}
5. Set V_(ENA) > V_{EN_IR}
