Quad Voltage µP Supervisory Circuit

in SOT Package

General Description

Features

The MAX6339 is a precision quad voltage monitor with

microprocessor (µP) supervisory reset timing. The device

can monitor up to four system supply voltages without

any external components and asserts a single reset if any

supply voltage drops below its preset threshold. The

device significantly reduces system size and component

count while improving reliability compared to separate

ICs or discrete components.

♦ Monitors Four Power-Supply Voltages

♦ Precision Factory-Set Reset Threshold Options

for +5.0V, +3.3V, +3.0, +2.5V, +1.8V, and -5.0V

Supplies

♦ User-Adjustable Voltage Monitoring Threshold

Options

♦ Low 55µA Supply Current

A variety of factory-trimmed threshold voltages are avail-

able to accommodate different supply voltages and toler-

ances with minimal external component requirements.

The selection includes internally fixed options for monitor-

ing +5.0V, +3.3V, +3.0V, +2.5V, +1.8V, and -5.0V sup-

plies with -5% and/or -10% tolerances. The device is also

available with one or two user-adjustable threshold

options if non-standard thresholds are desired (use exter-

nal resistor-divider network).

♦ Open-Drain RESET Output with 10µA Internal

Pullup

♦ 140ms (min) Reset Timeout Period

♦ RESET Valid to IN1 = 1V or IN2 = 1V

♦ Immune to Short Monitored Supply Transients

♦ No External Components Required

♦ Guaranteed from -40°C to +85°C

♦ Small 6-Pin SOT23 Package

The quad monitor provides a single active-low reset out-

put that is asserted when any monitored input is below its

associated threshold. The output is open drain with a

weak internal pullup (10µA) to IN2. Reset remains low for

a reset timeout period (140ms min) after all voltages are

above the selected thresholds. The output is valid as long

as either the IN1 or IN2 input voltage remains > 1V.
