The overtemperature protection holds off the GaN power FET if the LMG3624 temperature is above the overtemperature protection temperature. Figure 7-3 shows the overtemperature protection hold-off (blocking) operation. The overtemperature protection hysteresis avoids erratic thermal cycling.
An overtemperature fault is reported on the FLT pin when the overtemperature protection is asserted. This is the only fault event reported on the FLT pin. The overtemperature protection is enabled when the AUX voltage is above the AUX power-on reset voltage. The low AUX power-on reset voltage helps the overtemperature protection remain operational when the AUX rail droops during the application cool-down phase.
