MAX6412–MAX6420
Low-Power, Single/Dual-
Voltage μP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay
General Description
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. The MAX6415/MAX6416/ MAX6417 are offered with an adjustable reset input that can monitor
voltages down to 1.26V and the MAX6418/ MAX6419/MAX6420 are offered with one fixed input and one adjustable input to monitor dual-...
