MAX6765–MAX6774

Automotive Micropower Linear Regulators

with Supervisor

General Description

Features

● Low 31μA Quiescent Current

The MAX6765–MAX6774B are low-quiescent-current,

high-voltage linear regulators that operate from 4V to 72V

and deliver up to 100mA of load current. These low-power

devices consume only 31µA of quiescent current, mak-

ing them ideal for always-on automotive modules. These

devices are offered with fixed standard output options of

5.0V, 3.3V, 2.5V, and 1.8V, or can be adjusted from 1.8V

to 11V with two external resistors.

● 4V to 72V Wide Input Voltage Range

● 100mA Output Current Capability

● Dropout Voltage of 620mV with 5V Output at 100mA

● Fixed Output-Voltage Options: 5V, 3.3V, 2.5V, and 1.8V

● Watchdog Timer Option (1.6s (MAX6773/MAX6774)

and 50ms (MAX6773B/MAX6774B))

● Adjustable Output Voltages from 1.8V to 11V

● Open-Drain or Push-Pull RESET Output

● Fixed or Capacitor-Adjustable Reset Timeouts

● Small, Thermally Enhanced 1.9W, 3mm x 3mm

TDFN Package

● Overtemperature and Short-Circuit Protection

● Fully Specified from -40°C to +125°C

● AEC-Q100 qualified (MAX6765TT_D_/V+,

MAX6767TA_D_/V+, MAX6769TA_D_/V+,

MAX6773TA_D_/V+ , MAX6773BTA_D_/V+ only)

The MAX6765–MAX6774B feature a push-pull or open-

drain, active-low RESET output with either fixed or adjustable

thresholds. Whenever the regulator’s output falls below

the reset threshold, the RESET output asserts and

remains asserted for at least the minimum reset timeout

period after the output voltage exceeds its threshold. The

minimum reset timeout period is offered with fixed values

from 75µs to 200ms or can be adjusted externally with a

small capacitor.

These devices provide three regulator enable modes

to accommodate several power-on schemes. The

MAX6765/MAX6766/MAX6769/MAX6770/MAX6773/

MAX6773B/MAX6774/MAX6774B feature a single tradi-

tional enable input (ENABLE) to turn on and off the regu-

lator. The MAX6771/MAX6772 provide dual enable inputs

(ENABLE1 and ENABLE2) to turn on and off the regulator

either through an ignition switch or a bus transceiver. The

MAX6767/MAX6768 provide a hold input (HOLD) in addi-

tion to the enable input to allow for the implementation of a

self-holding circuit without requiring external components.

Setting HOLD low after enabling the regulator forces the

regulator to remain on even if ENABLE is subsequently

set low. Releasing HOLD shuts down the regulator.

Ordering Information continued at end of data sheet.

The first “_” is a placeholder for the voltage output and reset

threshold. The 2nd “_” designates the fixed reset-timeout option.

See Tables 1 and 2 for details. For example, the MAX6765TTLD4

has a 5V output, a reset threshold of 4.65V, and a 200ms typical

reset timeout.

The MAX6773/MAX6773B/MAX6774/MAX6774B also

include a watchdog input that monitors a pulse train from

the microprocessor (µP) and generates a reset pulse if

the watchdog input remains high or low for a duration

longer than the 1.6s (typ) (MAX6773/MAX6774) or 50ms

(typ) (MAX6773B/MAX6774B) watchdog timeout period.

+Denotes a lead(Pb)-free/RoHS-compliant package.

/V denotes an automotive qualified part.

*EP = Exposed pad.

For tape-and-reel orders add a “T” after the “+” symbol to com-

plete the part number. Tape-and-reel orders are available in

2.5k increments. Nonstandard versions require a 10k minimum

order quantity.

The MAX6765–MAX6774B are available in a small, ther-

mally enhanced 3mm x 3mm TDFN package that can

dissipate up to 1.951W, thereby supporting continuous

regulator operation during high ambient temperatures,

high battery voltage, and high load-current conditions.
