9.2.2. Latch-type overcurrent protection operation
In the case of latch-type overcurrent protection, the protection operation latches during thermal protection. To reset, it is necessary to restart by reapplying a control signal to the EN pin or voltage to the VIN pin. The protection operation continues until the restart.
