8.4 Device Functional Modes

The LMG3624 has two modes of operation controlled by the EN pin. The device is in active mode when the EN is logic high and in standby mode when the EN pin is logic low. In active mode, the power FET is controlled by the IN pin. In standby mode, the IN pin is ignored, the GaN power FET is held off, and the AUX quiescent current is reduced to the AUX standby quiescent current.
