Low-Power Dual-/Triple-Voltage SC70 µP

Supervisory Circuits

General Description

Features

The MAX6736–MAX6745 are low-power dual-/triple-

voltage microprocessor (µP) supervisors. These

devices assert a reset if any monitored supply falls

below its factory-trimmed or adjustable threshold and

maintain reset for a minimum timeout period after all

supplies rise above their thresholds. The integrated

dual/triple supervisory circuits significantly reduce size

and power compared to separate ICs or discrete com-

ponents. The low supply current of 6µA makes these

devices ideal for portable equipment.

♦ Dual-/Triple-Supply Reset Voltage Monitors

♦ Precision Factory-Set Reset Thresholds for

Monitoring from 0.9V to 5.0V

♦ Adjustable Reset Input Down to 0.488V

♦ 150ms and 1200ms (min) Reset Timeout Period

Options

♦ V 1 Power-OK Output for Power-Supply

Sequencing Applications (MAX6741/MAX6744)

♦ Power-Fail Input/Power-Fail Output

The MAX6736/MAX6737 are dual fixed-voltage µP

supervisors with a manual reset input. The MAX6738/

MAX6739 have one fixed and one adjustable reset

threshold and a manual reset input. The MAX6740/

MAX6743 are triple-voltage µP supervisors with two

fixed and one user-adjustable reset threshold inputs.

The MAX6741/MAX6744 are dual-voltage µP supervi-

sors with a power-OK (POK) output ideal for power-

supply sequencing. The MAX6742/MAX6745 monitor

(MAX6742/MAX6745)

♦ 6µA Supply Current

♦ Tiny SC70 Package

Note: The first “_ _” or “_” are placeholders for the threshold

voltage levels of the devices. Desired threshold levels are set

by the part number suffix found in Tables 1 and 2. The “_” after

the D is a placeholder for the reset timeout period suffix found

in Table 3. For example, the MAX6736XKLTD3-T is a dual-volt-

The MAX6736–MAX6745 monitor I/O supply voltages

(V 1) from 1.8V to 5.0V and core supply voltages

(V 2) from 0.9V to 3.3V with factory-trimmed reset

threshold voltage options (Table 1). An external

adjustable RSTIN input option allows monitoring volt-

ages down to 0.5V.

age supervisor V 1 = 4.625V, V 2 = 3.075V, and a 150ms

minimum reset timeout period. All devices are available in

tape-and-reel only. There is a 2500-piece minimum order

increment for standard versions (see Table 1). Sample stock is

typically held on standard versions only. Nonstandard versions

require a minimum order increment of 10,000 pieces. Contact

factory for availability.

A variety of push-pull or open-drain reset outputs along

with manual reset input and power-fail input/output fea-

tures are available (see the Selector Guide). The

MAX6736–MAX6745 are offered in a space-saving 5-pin

SC70 package and operate over the -40°C to +85°C

temperature range.

Devices are available in both leaded and lead-free packaging.

Specify lead-free by replacing “-T” with “+T” when ordering.
