Product details
Overview
MAX6767TALD2+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 current at 5.0V fixed output, features 31µA quiescent current, 12.5ms fixed reset timeout (D2 suffix), and AEC-Q100 qualification - designed for always-on vehicle modules such as body control units and telematics gateways.
For engineers reviewing the MAX6767TALD2+T datasheet, MAX6767TALD2+T pinout, MAX6767TALD2+T application, or MAX6767TALD2+T equivalent, this page provides verified technical context, exact pin functions, real-world automotive use cases, and validated alternative parts - all grounded in Maxim's official documentation and electrical specifications.
Technical Context
The MAX6767TALD2+T integrates a high-voltage linear regulator with dual-mode enable logic: ENABLE (active-high) and HOLD (active-low). When HOLD is pulled low after enabling, the regulator remains on even if ENABLE returns low - enabling ignition-controlled self-holding without external latching components. Its supervisor includes an open-drain active-low RESET output with fixed 12.5ms timeout (D2), triggered when VOUT falls below 4.625V (L-suffix threshold).
This device belongs to the MAX6765–MAX6774B family and implements Dual Mode™ SET architecture: SET pin accepts either GND (for fixed 5.0V output) or a resistive divider (to adjust output from 1.8V to 11V). It lacks watchdog timer (unlike MAX6773/MAX6774 variants) and dual-enable inputs (unlike MAX6771/MAX6772), confirming its role as a hold-enabled, single-enable supervisor regulator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 72V - supports full automotive battery range including cold-crank (4.5V) and load-dump (up to 72V) transients. |
| Output Voltage | Fixed 5.0V ±1.5% (L-suffix) - stable supply for MCU cores, CAN transceivers, and sensor interfaces. |
| Quiescent Current | 31µA typical - enables >10-year battery standby in always-on modules without excessive drain. |
| Reset Threshold | 4.625V (L-suffix, falling edge) - asserts RESET before microcontroller brownout, ensuring safe shutdown. |
| Reset Timeout | 12.5ms (D2 suffix) - guarantees µP reset pulse width meets ARM Cortex-M and Infineon AURIX timing requirements. |
| Dropout Voltage | 620mV at 100mA (5V output) - maintains regulation down to VIN = 5.62V, critical during engine cranking. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis - prevents thermal runaway under sustained high-ambient conditions. |
Pinout & Package
MAX6767TALD2+T uses a thermally enhanced 6-pin TDFN-EP package (3mm × 3mm, outline 21-0137), rated for 1.951W power dissipation on multilayer PCBs. Exposed pad (EP) must be soldered to ground plane for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Bypassed to GND with ≥0.1µF ceramic capacitor; withstands 80V absolute max - handles load dump without external TVS. |
| 2 GND | Ground Reference | Power and signal return; EP internally connected to GND - requires solid thermal pad connection. |
| 3 ENABLE | Active-High Enable | Pulled down internally (0.6µA); driven high by ignition switch or MCU GPIO to initiate startup sequence. |
| 4 RESET | Active-Low Open-Drain Reset Output | Drives µP reset pin; requires external pull-up; asserts low for ≥12.5ms after VOUT recovers above 4.625V. |
| 5 TIMEOUT | Reset Timeout Adjust | Connected to OUT for fixed D2 (12.5ms) timeout; floating or capacitor-connected for adjustable timing. |
| 6 OUT | Regulated Output | 5.0V supply rail; bypassed with ≥10µF low-ESR capacitor; supports 100mA continuous load. |
Key Features
| Feature | Design Value |
|---|---|
| Self-Holding Enable Logic | HOLD input allows regulator to stay on after ENABLE goes low - eliminates need for external latch circuitry in ignition-switched systems. |
| AEC-Q100 Qualified | Rated for -40°C to +125°C operation with full automotive reliability testing - suitable for under-hood and dashboard applications. |
| Low Dropout at Full Load | 620mV dropout at 100mA ensures regulation during 12V battery sag to 5.62V - critical for engine start scenarios. |
| Integrated Thermal & Short-Circuit Protection | Auto-recovering shutdown at 160°C and current limiting to 150–250mA prevent damage during fault conditions. |
| Adjustable or Fixed Output | SET pin supports both fixed 5.0V (via GND tie) and adjustable 1.8V–11V (via resistor divider) - simplifies BOM across voltage variants. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator with supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6765TALD2+T | No HOLD pin; single ENABLE only; identical 5V/4.625V/D2 specs and package. | Lacks self-holding capability - requires external latch or MCU firmware coordination for ignition hold behavior. | Select when system design uses MCU-managed enable sequencing instead of hardware-based hold. |
| MAX6769TALD2+T | Includes RESETIN pin for monitoring external voltage rails; same 5V output and D2 timeout. | Supports independent supervision of battery or MCU core voltage - not limited to regulating output monitoring. | Select when supervising non-regulated rails (e.g., 12V battery or 3.3V MCU domain) alongside 5V regulation. |
Compared with MAX6765TALD2+T, MAX6767TALD2+T adds hardware hold functionality without increasing quiescent current or footprint; compared with MAX6769TALD2+T, it trades RESETIN flexibility for simplified enable logic - making it optimal for ignition-gated 5V domains where hold behavior is mandatory.

FAQ
What is the function of the HOLD pin on the MAX6767TALD2+T?
The HOLD pin on the MAX6767TALD2+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. This allows ignition-switched systems to maintain power during key-off states without external latching components. Releasing HOLD shuts down the MAX6767TALD2+T output.
Does the MAX6767TALD2+T include a watchdog timer?
No, the MAX6767TALD2+T does not include a watchdog timer. Watchdog functionality is exclusive to the MAX6773/MAX6773B/MAX6774/MAX6774B variants in the family. The MAX6767TALD2+T provides only reset supervision based on its regulated 5.0V output voltage and fixed 12.5ms timeout - confirmed by its absence in the functional diagram and electrical characteristics tables.
What is the maximum load current supported by the MAX6767TALD2+T at 5V output?
The MAX6767TALD2+T guarantees 100mA continuous output current at 5.0V under specified thermal conditions. Its actual deliverable current depends on input voltage, ambient temperature, and PCB thermal design - for example, at VIN = 14V and TA = +70°C on a multilayer board, it sustains 100mA with margin; at VIN = 72V, power dissipation limits usable current to ~25mA unless heatsinking is enhanced.
How is the reset timeout period set on the MAX6767TALD2+T?
The reset timeout period on the MAX6767TALD2+T is set by the D2 suffix, corresponding to a fixed 12.5ms timeout. This is implemented by internal circuitry when the TIMEOUT pin is connected to the OUT pin - no external capacitor is required. The TIMEOUT pin may be left unconnected or tied to OUT; capacitor-based adjustment is not used in D2-configured devices.
Is the MAX6767TALD2+T qualified for automotive applications?
Yes, the MAX6767TALD2+T is AEC-Q100 qualified (Grade 0, -40°C to +125°C) and explicitly listed among the automotive-qualified variants in the datasheet's Ordering Information table. Its thermal protection, wide input range, low quiescent current, and 5.0V output stability meet stringent automotive requirements for body electronics and infotainment systems.
