描述
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 P-channel load switch to remove power when an over-voltage 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 µMAX® package.
