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.
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.
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.
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.
The MAX6765–MAX6774B are fully specified for a -40°C
to +125°C operating temperature range.
Ordering Information
PART
MAX6765TT_D_+
MAX6765TT_D_/V+
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.
+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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
