Description

The MAX1807/MAX1808 monitor up to five supply rails for an overvoltage condition and provide a latched output when any one of the five supplies exceeds the trip thresholds. The latched output drives an external Pchannel load switch to remove power when an overvoltage condition is detected. The latch is reset when a logic low is input to ON or the power supply is cycled.

The MAX1807 provides a 28V open-drain fault output that can be used to trigger an alert, trip a resetable fuse, or for other purposes. The MAX1808 includes a low-battery comparator with hysteresis to drive the DP output high, turning off the external P-channel switch when the input voltage is too low.

The MAX1807/MAX1808 are available in a miniature 10- pin MAX package
