7.4.1 State 1: RESET

When a valid power supply is first applied to VCC1, the device enters the RESET state. In the RESET state, the device does not respond to commands from MCU, the driver outputs (OUTL and OUTH) are both high impedance, the registers are reset to the default values, and all of the built In Self Tests (BIST) run. The nFLTx outputs are held low until a power source is connected to VCC2, all of the automatic BISTs complete, and the device transitions to the Configuration 1 state. After transitioning from Reset, the device only returns to the Reset state if the power is cycled, or if the primary side over temperature is detected. The secondary over temperature event does not cause the state transition to RESET unless the primary side also detects the over temperature event.
