PRODUCTION DATA.
The over-temperature protection circuit measures the temperature of the driver die and trips if the temperature exceeds the over-temperature threshold (typically 165 °C). Upon an over-temperature condition, the GaN device is held off until temperature falls below the hysteresis limit, typically 15 degrees below the turn-off threshold.
The FAULT output is a push-pull output indicating the readiness and fault status of the driver. It is held low when starting up until the safety FET is turned on. In an OCP or OTP fault condition, it is held low until the fault latches are reset or fault is cleared. If the power supplies go below the UVLO thresholds, power transistor switching is disabled and FAULT is held low until the power supplies recover.
