Micropower Adjustable Overvoltage  
Protection Controllers  
General Description  
Features  
The MAX1807/MAX1808 monitor up to five supply rails  
for an overvoltage condition and provide a latched out-  
put 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.  
o Five 3% Accurate Overvoltage Comparators  
o Series PFET Gate Driver with VGS Limiter  
o 21µA Quiescent Supply Current  
o 4µA Shutdown Current  
o 4.4V to 28V Operating Voltage Range  
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.  
o 3% Accurate Comparator with 10% Hysteresis for  
Low-Battery Detection (MAX1808)  
o 28V Open-Drain N-Channel Output (MAX1807)  
o Small 10-Pin µMAX Package  
The MAX1807/MAX1808 are available in a miniature 10-  
pin µMAX package.
