MAX6402BS22+T IC SUPERVISOR MPU 4-UCSP Analog Devices Inc./Maxim Integrated

 

General Description

The MAX6400–MAX6405 is a family of ultra-low power microprocessor (µP) supervisory circuits used for monitoring battery, power-supply, and regulated system voltages. Each device contains a precision bandgap
reference comparator and is trimmed to specified trip threshold voltages. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring system voltages from 2.5V to 5.0V. A manual reset input is also included.
