SC70/µDFN, Single/Dual Low-Voltage,

Low-Power µP Reset Circuits

General Description

The MAX6381–MAX6390 microprocessor (µP) supervisory

circuits monitor power-supply voltages from +1.8V to

+5.0V while consuming only 3µA of supply current at

+1.8V. Whenever V

falls below the factory-set reset

thresholds, the reset output asserts and remains assert-

ed for a minimum reset timeout period after V

rises

above the reset threshold. Reset thresholds are available

from +1.58V to +4.63V, in approximately 100mV incre-

ments. Seven minimum reset timeout delays ranging

from 1ms to 1200ms are available.

The MAX6381/MAX6384/MAX6387 have a push-pull

active-low reset output. The MAX6382/MAX6385/

MAX6388 have a push-pull active-high reset output,

and the MAX6383/MAX6386/MAX6389/MAX6390

have an open-drain active-low reset output. The

MAX6384/MAX6385/MAX6386 also feature a

debounced manual reset input (with internal pullup

resistor). The MAX6387/MAX6388/MAX6389 have an

auxiliary input for monitoring a second voltage. The

MAX6390 offers a manual reset input with a longer V

reset timeout period (1120ms or 1200ms) and a shorter

manual reset timeout (140ms or 150ms).

The MAX6381/MAX6382/MAX6383 are available in

3-pin SC70 and 6-pin µDFN packages and the

MAX6384–MAX6390 are available in 4-pin SC70 and

6-pin µDFN packages.
