... Q10% accuracy. During a fault condi- tion, the MAX5976A enters an autoretry mode while the MAX5976B latches off. Both versions feature a resistor- adjustable variable speed circuit-breaker threshold and overtemperature protection. Additional features include power-good and fault indicator outputs ...

... During a fault condition, the devices turn off the inter- nal MOSFET disconnecting the output from the input. The MAX5976A enters an autoretry mode with a fixed 250ms lockout time before reconnect can occur. The MAX5676B latches off and remains off until the enable OUT logic is cycled off and on ...
