Analog Devices Inc./Maxim Integrated MAX6765TTSD2/V+T

Overview

MAX6765TTSD2/V+T from Maxim Integrated is an automotive-qualified micropower linear regulator with integrated supervisor, delivering 5.0V fixed output at up to 100mA from 4V–72V input. It features 31µA quiescent current, 620mV dropout at 100mA, open-drain active-low RESET with 12.5ms fixed timeout (D2 suffix), and operates across –40°C to +125°C - ideal for always-on body control modules and infotainment power rails.

For engineers reviewing the MAX6765TTSD2/V+T datasheet, MAX6765TTSD2/V+T pinout, MAX6765TTSD2/V+T application, or MAX6765TTSD2/V+T equivalent, key selection factors include its AEC-Q100 qualification, thermally enhanced 3mm × 3mm TDFN-6 package, watchdog-free supervisor architecture, and compatibility with high-temperature under-hood environments requiring stable 5V bias for microcontrollers and sensors.

Technical Context

The MAX6765TTSD2/V+T implements a single-enable (ENABLE) linear regulator topology with internal 5.0V reference and precision reset comparator monitoring OUT voltage against a 4.625V threshold (L-suffix). Its RESET output is open-drain, active-low, and remains asserted for ≥12.5ms after V_OUT recovers above threshold - meeting ISO 16750-2 cold-crank brownout recovery requirements.

Thermal protection activates at +160°C (typ) with 20°C hysteresis, and overcurrent limiting sustains 150–250mA short-circuit current. The device draws only 3.3µA in shutdown (ENABLE = GND) and maintains ±1.5% load regulation (1–100mA) and ±1% line regulation (6.5–72V), enabling robust operation across battery transients.

FAQ

What is the reset timeout period for MAX6765TTSD2/V+T?

The MAX6765TTSD2/V+T has a fixed reset timeout period of 12.5ms, indicated by the "D2" suffix in the part number. This timeout begins when the output voltage rises above the 4.625V reset threshold and ensures the RESET signal remains asserted for ≥12.5ms to meet automotive microcontroller reset-hold requirements. The TIMEOUT pin is internally connected to OUT to enable this fixed timing.

Is MAX6765TTSD2/V+T qualified for automotive use?

Yes, MAX6765TTSD2/V+T is AEC-Q100 qualified (Grade 1) and explicitly listed in the datasheet as an automotive-qualified part ("/V+" suffix). It is fully specified from –40°C to +125°C, includes thermal shutdown and short-circuit protection, and meets automotive reliability and stress-test requirements for under-hood and cabin applications.

What package type does MAX6765TTSD2/V+T use?

MAX6765TTSD2/V+T uses a 3mm × 3mm, 6-pin TDFN-EP (Thin Dual Flat No-lead with Exposed Pad) package (package code T633+2). The exposed pad must be soldered to the PCB ground plane to achieve the specified thermal performance (θ_JA = 42°C/W on multi-layer board) and 1.951W power dissipation capability.

Does MAX6765TTSD2/V+T include a watchdog timer?

No, MAX6765TTSD2/V+T does not include a watchdog timer. It belongs to the MAX6765/MAX6766 subgroup, which features only enable-controlled regulation and supervisor reset functionality. Watchdog capability is present only in MAX6773/MAX6774 (1.6s timeout) and MAX6773B/MAX6774B (50ms timeout) variants - not in the TTSD2 suffix series.

What is the maximum output current of MAX6765TTSD2/V+T?

The MAX6765TTSD2/V+T delivers up to 100mA of continuous output current. Actual available current depends on thermal conditions: at +70°C ambient, with the 3mm × 3mm TDFN package mounted on a multi-layer PCB, it supports 100mA with VIN = 14V and VOUT = 5V while staying within safe junction temperature limits. Derating applies at higher ambient temperatures or input voltages.
