µP Supervisory Circuits in 4-Bump (2 ✕ 2) Chip-Scale Package
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.
The MAX6400–MAX6405 assert a reset signal whenever the VCC supply
voltage falls below a preset threshold.
