MAX6381–MAX6390

SC70/μDFN, Single/Dual Low-Voltage,

Low-Power μP Reset Circuits

General Description

The MAX6381–MAX6390 microprocessor (μP) supervi-

sory circuits monitor power-supply voltages from +1.8V

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

Features

● Factory-Set Reset Threshold Voltages Ranging from

+1.58V to +4.63V in Approximately 100mV Increments

● ±2.5% Reset Threshold Accuracy Over

Temperature (-40°C to +125°C)

+1.8V. Whenever V

falls below the factory-set reset

thresholds, the reset output asserts and remains asserted

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 increments.

Seven minimum reset timeout delays ranging from 1ms

to 1200ms are available.

● Seven Reset Timeout Periods Available: 1ms, 20ms,

140ms, 280ms, 560ms, 1120ms, 1200ms (min)

● 3 Reset Output Options

• Active-Low Push-Pull

• Active-High Push-Pull

• Active-Low Open-Drain

TheMAX6381/MAX6384/MAX6387haveapush-pullactive-

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

● Reset Output State Guaranteed Valid Down to V = 1V

● Manual Reset Input (MAX6384/MAX6385/MAX6386)

● Auxiliary RESET IN (MAX6387/MAX6388/MAX6389)

● V

Reset Timeout (1120ms or 1200ms)/Manual

Reset Timeout (140ms or 150ms) (MAX6390)

● Negative-Going V Transient Immunity

● Low Power Consumption of 6μA at +3.6V and 3μA at +1.8V

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).

● Pin Compatible with MAX809/MAX810/MAX803/

MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/

MAX6348, and MAX6711/MAX6712/MAX6713

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.

Note: Insert reset threshold suffix (see Reset Threshold table)

after “XR”, “XS”, or “LT.” Insert reset timeout delay (see Reset

Timeout Delay table) after “D” to complete the part number.

Sample stock is generally held on standard versions only (see

Standard Versions table). Standard versions have an order

increment requirement of 2500 pieces. Nonstandard versions

have an order increment requirement of 10,000 pieces.

Contact factory for availability of nonstandard versions.
