General Description
The MAX6406–MAX6411 is a family of ultra-low power circuits used for monitoring battery, power-supply, and regulated system voltages. Each detector 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.
