µP Reset Circuits with Capacitor-Adjustable

Reset/Watchdog Timeout Delay

General Description

Features

The MAX6746–MAX6753 low-power microprocessor

(µP) supervisory circuits monitor single/dual system

supply voltages from 1.575V to 5V and provide maxi-

mum adjustability for reset and watchdog functions.

♦ Factory-Set Reset Threshold Options from 1.575V

to 5V in ~100mV Increments

♦ Adjustable Reset Threshold Options

♦ Single/Dual Voltage Monitoring

These devices assert a reset signal whenever the V

supply voltage or RESET IN falls below its reset thresh-

old or when manual reset is pulled low. The reset output

♦ Capacitor-Adjustable Reset Timeout

♦ Capacitor-Adjustable Watchdog Timeout

♦ Min/Max (Windowed) Watchdog Option

♦ Manual Reset Input Option

remains asserted for the reset timeout period after V

and RESET IN rise above the reset threshold. The reset

function features immunity to power-supply transients.

The MAX6746–MAX6753 have ±±2 factory-trimmed

reset threshold voltages in approximately 100mV incre-

ments from 1.575V to 5.0V and/or adjustable reset

threshold voltages using external resistors.

♦ Guaranteed RESET Valid for V

♦ 3.7µA Supply Current

≥ 1V

The reset and watchdog delays are adjustable with

external capacitors. The MAX6746–MAX6751 contain a

watchdog select input that extends the watchdog time-

out period by 1±8x. The MAX675±/MAX6753 contain a

window watchdog timer that looks for activity outside an

expected window of operation.

♦ Push-Pull or Open-Drain RESET Output Options

♦ Power-Supply Transient Immunity

♦ Small 8-Pin SOT23 Packages

The MAX6746–MAX6753 are available with a push-pull

or open-drain active-low RESET output. The MAX6746–

MAX6753 are available in an 8-pin SOT±3 package and

are fully specified over the automotive temperature

range (-40°C to +1±5°C).

Note: “_ _” represents the two number suffix needed when

ordering the reset threshold voltage value for the

MAX6746/MAX6747 and MAX6750–MAX6753. The reset

threshold voltages are available in approximately 100mV incre-

ments. Table 2 contains the suffix and reset factory-trimmed

voltages. All devices are available in tape-and-reel only. There

is a 2500-piece minimum order increment for standard ver-

sions (see Table 3). Sample stock is typically held on standard

versions only. Nonstandard versions require a minimum order

increment of 10,000 pieces. Contact factory for availability.
