MAXIM MAX6375 MAX6380 handbook
The MAX6375-MAX6380 are ultra-low-power circuits used for monitoring battery, power-supply, and regulated system voltages. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from 2.5V to 5V. These circuits assert an output signal whenever the VCC supply voltage falls below a preset threshold.
