Product details
Overview
MAX6767TALD1+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 up to 100mA output at 5.0V (fixed), features 31µA quiescent current, 620mV dropout at 100mA, and AEC-Q100 qualification - designed for always-on vehicle modules such as body control units and telematics gateways.
For engineers reviewing the MAX6767TALD1+T datasheet, MAX6767TALD1+T pinout, MAX6767TALD1+T application, or MAX6767TALD1+T equivalent, key selection criteria include its HOLD/ENABLE dual-control architecture, capacitor-adjustable 3.125ms reset timeout (D1 suffix), 5V fixed output with 4.625V reset threshold (L suffix), and thermally enhanced 3mm × 3mm TDFN-6 package rated for -40°C to +125°C operation.
Technical Context
The MAX6767TALD1+T implements a high-voltage linear regulation core with dual-input control logic: ENABLE (active-high) initiates regulation, while HOLD (active-low) latches the output ON even after ENABLE is deasserted - enabling ignition-switch-based self-holding without external components. Its supervisor block monitors OUT voltage and asserts an open-drain/push-pull RESET when falling below 4.625V, holding low for ≥3.125ms after recovery.
This variant belongs to the MAX6767–MAX6774B family with adjustable-output capability (via SET pin), but MAX6767TALD1+T uses internal feedback for fixed 5.0V output (L suffix). It includes overtemperature shutdown (160°C trip, 20°C hysteresis), short-circuit protection, and 1.9W thermal dissipation in the 6-pin TDFN-EP package - validated for continuous operation under high ambient, high VIN, and full-load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 72V - supports wide automotive battery transients including load dump up to 80V absolute max. |
| Output Voltage | Fixed 5.0V ±1.5% (L suffix) - stable supply for microcontrollers, CAN transceivers, and sensors. |
| Quiescent Current | 31µA typical - enables <100µA system standby power for ISO 16750-compliant always-on modules. |
| Dropout Voltage | 620mV at 100mA (VIN = 11V) - ensures regulation down to 5.62V input, critical during cold-crank conditions. |
| Reset Threshold | 4.625V (L option, falling edge) - triggers reset before MCU brownout, with guaranteed hysteresis. |
| Reset Timeout | 3.125ms typical (D1 suffix, TIMEOUT-to-OUT connection) - meets automotive reset timing requirements per SAE J1939 and ISO 11898. |
| Operating Temp | -40°C to +125°C - fully specified junction temperature range for under-hood deployment. |
| AEC-Q100 Grade | Qualified (Grade 1) - certified for automotive production use per AEC-Q100 Rev H. |
Pinout & Package
Package: 6-pin TDFN-EP (3mm × 3mm, exposed pad), thermal resistance θJA = 42°C/W (multi-layer board), capable of 1.951W continuous dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Accepts 4V–72V; bypass to GND with ≥0.1µF ceramic capacitor for stability and transient immunity. |
| 2 GND | Ground Reference | Power and signal return; connects internally to exposed pad (EP) - must be soldered to PCB ground plane. |
| 3 ENABLE | Active-High Enable | Drives regulator ON when pulled >1.4V; internally pulldown (0.6µA) - compatible with 3.3V/5V logic. |
| 4 RESET | Active-Low Reset Output | Open-drain or push-pull; asserts low when OUT < 4.625V and holds for ≥3.125ms post-recovery. |
| 5 TIMEOUT | Reset Timeout Adjust | Connected to OUT for fixed 3.125ms timeout (D1); capacitor-to-GND enables adjustable timing. |
| 6 OUT | Regulated Output | 5.0V @ up to 100mA; bypass to GND with ≥10µF capacitor; protected against overvoltage (1.1×VOUT). |
Key Features
| Feature | Design Value |
|---|---|
| Self-holding circuitry | HOLD pin enables latch-on behavior: regulator stays active after ENABLE goes low, eliminating need for external hold circuitry. |
| Automotive thermal robustness | 1.951W power dissipation in 3mm × 3mm TDFN-EP package supports continuous operation at +125°C ambient with 72V input. |
| Low-power supervision | Integrated reset generator consumes only 31µA total - no separate supervisor IC required for cost-sensitive modules. |
| High-voltage fault tolerance | Withstands 80V absolute max on IN and 12V on RESET/WDI pins - survives load dump and jump-start events. |
| AEC-Q100 qualification | Grade 1 qualified (−40°C to +125°C) - meets automotive reliability, ESD, and lifetime requirements for production ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive linear regulator with supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6765TALD1+T | No HOLD pin; single ENABLE only; identical 5V/4.625V/D1 configuration and thermal specs. | Lacks self-holding capability - requires external latch or MCU firmware coordination for ignition persistence. | Select when HOLD functionality is unnecessary and lowest BOM cost is prioritized. |
| TLV70750PDQNR | Lower input range (2.5V–5.5V), 200mA output, 25µA IQ, no RESET or HOLD - basic LDO only. | Not suitable for automotive battery rail; lacks supervision, high-voltage tolerance, or AEC-Q100 qualification. | Use only in low-voltage, non-automotive embedded systems where supervision is handled externally. |
Compared with MAX6765TALD1+T, the MAX6767TALD1+T adds HOLD-based latching without increasing footprint or thermal footprint - enabling simpler ignition sequencing. Compared with TLV70750PDQNR, it provides full automotive-grade supervision, high-voltage operation, and AEC-Q100 compliance - essential for under-hood deployment.

FAQ
What is the function of the HOLD pin on the MAX6767TALD1+T?
The HOLD pin on the MAX6767TALD1+T is an active-low input that enables self-holding behavior: when pulled low after ENABLE is asserted, the regulator remains ON even if ENABLE subsequently goes low. Releasing HOLD shuts down the output. This eliminates external latch circuitry in ignition-controlled systems - a core differentiator of the MAX6767TALD1+T versus standard regulators like the MAX6765TALD1+T.
Does the MAX6767TALD1+T support adjustable output voltage?
Yes, the MAX6767TALD1+T supports adjustable output voltage from 1.8V to 11V via the SET pin and an external resistive divider. However, the MAX6767TALD1+T variant uses the L suffix, which configures internal feedback for fixed 5.0V output - SET must be connected to GND. Adjustable operation requires selecting a different suffix (e.g., MAX6767TBD1+T for 3.3V adjustable mode) per the ordering guide.
What reset timeout period is implemented by the D1 suffix in MAX6767TALD1+T?
The D1 suffix in MAX6767TALD1+T specifies a typical reset timeout period of 3.125ms. This is achieved by connecting the TIMEOUT pin directly to the OUT pin. The device guarantees a minimum timeout of 2.187ms and maximum of 4.063ms across temperature and process variation - meeting stringent automotive reset timing requirements for microcontroller initialization.
Is the MAX6767TALD1+T qualified for automotive applications?
Yes, the MAX6767TALD1+T is AEC-Q100 qualified (Grade 1) for operation from −40°C to +125°C. It is explicitly listed in the datasheet's AEC-Q100 qualified part table (MAX6767TA_D_/V+ series), confirming its suitability for production automotive ECUs including body control, telematics, and ADAS subsystems.
What package type and thermal performance does the MAX6767TALD1+T use?
The MAX6767TALD1+T uses a 6-pin TDFN-EP package (3mm × 3mm) with exposed pad. On a multi-layer PCB, it achieves θJA = 42°C/W and can dissipate up to 1.951W continuously - enabling full 100mA output at 72V input and +125°C ambient without derating. The exposed pad must be soldered to the PCB ground plane for optimal thermal performance.
