Automotive Micropower Linear Regulators
with Supervisor
General Description
The MAX6765–MAX6774 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, making
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.
The MAX6765–MAX6774 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/
MAX6774 feature a single traditional enable input
(ENABLE) to turn on and off the regulator. 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.
The MAX6773/MAX6774 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) watchdog timeout period.
The MAX6765–MAX6774 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.
The MAX6765–MAX6774 are fully specified for a -40°C to
+125°C operating temperature range.

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.

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.
