... During startup, an internal power FET regulates the cur- rent between the backplane power source and the load to 280mA for MAX5911 and 415mA for MAX5912. After startup, the FET is fully enhanced to reduce its on-resis- tance. To ensure robust operation, the MAX5911/ MAX5912 contain built-in safety features that prevent damage to the internal FET ...

... FAULT is pulled low and the FET is latched off. ENABLE must be pulsed low and then brought high again to release FAULT and enable V Applications Information The MAX5911 will output up to 280mA (typ) and the MAX5912 up to 415mA (typ). In applications where high heat is expected, use the MAX5912 for its superior Normal Operation ...

... The FAULT output is open-drain and is pulled low if the V OUT MAX5911/MAX5912 detect an undervoltage fault, a thermal fault, a power-not-good fault zero-current fault. See the Normal Operation section for specific details of fault operation. Connect FAULT to the logic supply with a pullup resistor; 3.3kΩ is sufficient in most cases ...
