The MAX6412–MAX6420 low-power microprocessor supervisor circuits monitor system voltages from 1.6V to 5V. These devices are designed to assert a reset signal whenever the VCC supply voltage or RESET IN falls below its reset threshold or the manual reset input is asserted.
The reset output remains asserted for the reset timeout period after VCC and RESET IN rise above the reset threshold and the manual reset input is deasserted. The reset timeout is externally set by a capacitor to provide more flexibility.
The MAX6412/MAX6413/MAX6414 feature fixed thresholds from 1.575V to 5V in approximately 100mV increments and a manual reset input.
