Analog Devices Inc./Maxim Integrated MAX6767TALD0+T

Overview

MAX6767TALD0+T from Maxim Integrated is an automotive-grade micropower linear regulator with integrated supervisor and self-holding enable logic. It operates from 4V to 72V input, delivers 100mA output at 5.0V (L-suffix), features 31µA quiescent current, 620mV dropout at 100mA, and AEC-Q100 qualification - designed for always-on vehicle modules such as body control units and infotainment power rails.

For engineers reviewing the MAX6767TALD0+T datasheet, MAX6767TALD0+T pinout, MAX6767TALD0+T application, or MAX6767TALD0+T equivalent, key selection criteria include its HOLD/ENABLE dual-control architecture, fixed 5V output with 4.625V reset threshold, 75µs reset timeout, thermal shutdown at +160°C, and operation across –40°C to +125°C ambient.

Technical Context

The MAX6767TALD0+T implements a high-voltage linear regulation stage with dual-input control logic: ENABLE (active-high) initiates startup, while HOLD (active-low) latches the regulator ON even after ENABLE is deasserted. Its internal 1.233V reference and SET pin support either fixed 5.0V output (SET = GND) or adjustable 1.8V–11V operation via external resistor divider.

Supervision includes an open-drain active-low RESET output triggered when OUT falls below 4.625V (L-suffix), with fixed 75µs timeout (D0 suffix). It integrates overtemperature protection (trip at +160°C, 20°C hysteresis) and short-circuit current limiting (150–250mA), and is qualified to AEC-Q100 Grade 1.

Key Specifications

Pinout & Package

MAX6767TALD0+T uses a thermally enhanced 6-pin TDFN-EP package (3mm × 3mm, exposed pad), rated for 1.951W dissipation on multilayer PCBs. The exposed pad (EP) must be soldered to PCB ground plane for thermal and electrical integrity.

FAQ

What is the function of the HOLD pin on the MAX6767TALD0+T?

The HOLD pin on the MAX6767TALD0+T is an active-low input that latches the regulator ON after ENABLE is asserted and then deasserted. When HOLD is driven low while ENABLE is high, the regulator remains active even if ENABLE returns low - enabling self-holding behavior for ignition-switched automotive systems without external components. MAX6767TALD0+T uses this feature to eliminate discrete latch circuits in body control modules.

Does the MAX6767TALD0+T support adjustable output voltage?

Yes, the MAX6767TALD0+T supports adjustable output voltage from 1.8V to 11V using an external resistor divider connected to the SET pin. However, the MAX6767TALD0+T variant is factory-configured for fixed 5.0V output (L-suffix), so SET must be tied to GND to activate the preset mode. To use adjustable mode, a different suffix (e.g., MAX6767TAJD0+T) is required - the MAX6767TALD0+T itself operates exclusively at 5.0V.

What is the reset timeout period for the MAX6767TALD0+T?

The MAX6767TALD0+T has a fixed reset timeout period of 75µs, indicated by the D0 suffix in the part number. This value is internally programmed and does not require external capacitor adjustment. The RESET output remains asserted for exactly 75µs after the regulated output voltage rises above the 4.625V threshold, ensuring compatibility with fast-boot microcontrollers in automotive applications. MAX6767TALD0+T guarantees this timing across –40°C to +125°C.

Is the MAX6767TALD0+T qualified for automotive use?

Yes, the MAX6767TALD0+T is AEC-Q100 qualified (Grade 1), fully specified for operation from –40°C to +125°C ambient temperature, and designed for automotive power domains including body electronics and infotainment. Its construction includes robust ESD protection, thermal shutdown with hysteresis, and validation for vibration, humidity, and extended temperature cycling - meeting OEM requirements for 15-year vehicle lifecycles. MAX6767TALD0+T carries the "/V+" suffix denoting automotive qualification.

How does the MAX6767TALD0+T handle thermal overload?

The MAX6767TALD0+T incorporates thermal shutdown protection that activates at +160°C (typical junction temperature) and recovers after cooling by 20°C hysteresis. During sustained overload, it cycles ON/OFF to limit average power dissipation and prevent permanent damage. The 3mm × 3mm TDFN-EP package with exposed pad enables 1.951W dissipation on multilayer boards - critical for maintaining 100mA output in high-ambient environments like engine compartments. MAX6767TALD0+T's thermal design ensures safe operation without external heatsinking.
