MAX6765–MAX6774
Automotive Micropower Linear Regulators
with Supervisor
General Description
Features
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,
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–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

tional enable input (ENABLE) to turn on and off the regula-
tor. 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.

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.
