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-voltage systems.

The MAX6412/MAX6415/MAX6418 have an active-

low, push-pull reset output. The MAX6413/MAX6416/

MAX6419 have an active-high, push-pull reset output and

the MAX6414/MAX6417/MAX6420 have an active-low,

open-drain reset output. All of these devices are offered

in a SOT23-5 package and are fully specified from -40°C

to +125°C.
