Product details
Overview
MAX6767TALD4+ 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 fixed 5.0V (L-suffix), features active-low open-drain/push-pull RESET with 200ms timeout (D4), and consumes only 31µA quiescent current - ideal for always-on vehicle modules such as body control units and telematics gateways.
For engineers reviewing the MAX6767TALD4+ datasheet, MAX6767TALD4+ pinout, MAX6767TALD4+ application, or MAX6767TALD4+ equivalent, key selection criteria include its HOLD/ENABLE dual-control architecture, AEC-Q100 qualification, thermal shutdown at +160°C, 620mV dropout at 100mA, and compatibility with high-ambient automotive environments (-40°C to +125°C).
Technical Context
The MAX6767TALD4+ implements a high-voltage linear regulation architecture with internal 1.233V reference and feedback via SET pin. Its HOLD input enables latch-up behavior: when pulled low after ENABLE activation, it sustains regulator output even if ENABLE returns low - eliminating need for external latching circuitry in ignition-controlled systems.
It integrates a supervisor block with RESET output asserting when OUT falls below 4.625V (L-threshold), holding low for ≥200ms after recovery. The TIMEOUT pin supports either internal fixed timeout (D4 = 200ms) or capacitor-adjustable timing, while overtemperature and short-circuit protection ensure robust operation under fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 72V - supports full automotive battery range including load dump (up to 80V absolute max). |
| Output Voltage | Fixed 5.0V ±1.5% - trimmed for precision across -40°C to +125°C; L-suffix denotes 5V option. |
| Quiescent Current | 31µA typical - enables ultra-low standby power for always-on ECUs without draining battery. |
| Dropout Voltage | 620mV at 100mA - ensures stable 5V output even at VIN = 5.62V, critical during cold-crank conditions. |
| RESET Threshold | 4.625V (L-option) - asserts reset before microcontroller brownout, with guaranteed hysteresis. |
| Reset Timeout | 200ms (D4 suffix) - meets automotive µP reset timing requirements per ISO 16750-2. |
| Thermal Protection | +160°C shutdown with +20°C hysteresis - prevents damage during sustained high-power dissipation. |
Pinout & Package
MAX6767TALD4+ uses a thermally enhanced 6-pin 3mm × 3mm TDFN-EP package (exposed pad soldered to PCB ground plane), rated for 1.951W continuous dissipation at TA ≤ +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Bypass with ≥0.1µF capacitor to GND; accepts 4V–72V supply with 80V absolute max rating. |
| 2 GND | Ground Reference | Primary return path; exposed pad (EP) must be connected to PCB ground for thermal performance. |
| 3 ENABLE | Active-High Enable | Drives regulator ON when high; internally pulled down (0.6µA sink) - compatible with open-collector signals. |
| 4 RESET | Active-Low Reset Output | Open-drain/push-pull output; asserts low when OUT < 4.625V and holds for ≥200ms after recovery. |
| 5 TIMEOUT | Reset Timeout Control | Connected to OUT for fixed 200ms timeout (D4); capacitor-to-GND enables adjustable timing. |
| 6 OUT | Regulated Output | 5.0V fixed output; bypass with ≥10µF capacitor; supports 100mA load with 620mV dropout at full current. |
Key Features
| Feature | Design Value |
|---|---|
| HOLD Input with Self-Holding Logic | Enables latch-on behavior: regulator stays active after ENABLE deactivation if HOLD is held low - eliminates external hold circuitry in ignition-switched systems. |
| AEC-Q100 Qualified | Qualified per AEC-Q100 Rev H Grade 1 (-40°C to +125°C), ensuring reliability for automotive safety-critical applications. |
| Low Dropout at High Load | 620mV dropout at 100mA enables operation down to VIN = 5.62V - maintains 5V supply during engine cranking (cold-crank). |
| Integrated Supervisor with Adjustable Timing | RESET assertion tied to precise 4.625V threshold and factory-set 200ms timeout (D4), configurable via TIMEOUT pin for custom µP reset windows. |
| Robust Fault Protection | Includes overtemperature shutdown (+160°C), short-circuit current limiting (150–250mA), and output overvoltage protection (1.07×VOUT). |

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 |
|---|---|---|---|
| MAX6765TALD4+ | No HOLD input; single ENABLE only; identical 5V/4.625V/200ms specs and package. | Suitable where self-holding is unnecessary - simpler enable sequencing, lower complexity. | Select MAX6765TALD4+ when system does not require latch-on behavior after ENABLE removal. |
| TLV70750PDQNR | Lower VIN range (2.5V–5.5V), no RESET supervision, no HOLD, 200mA output, SOT-23-5. | Limited to low-voltage post-regulation; lacks automotive qualification and high-VIN capability. | Use TLV70750PDQNR only in non-automotive, low-input-voltage applications where supervision is handled externally. |
Compared with MAX6765TALD4+, MAX6767TALD4+ adds HOLD functionality enabling ignition-latched operation without external components; compared with TLV70750PDQNR, it supports full automotive battery range, integrated RESET, AEC-Q100 qualification, and thermal robustness - making it uniquely suited for primary 5V rail generation in harsh automotive environments.

FAQ
What is the function of the HOLD pin on the MAX6767TALD4+?
The HOLD pin on the MAX6767TALD4+ enables self-holding behavior: when driven low after ENABLE activation, it keeps the regulator output active even if ENABLE subsequently goes low. This allows ignition-switched systems to maintain power without external latching circuitry. Releasing HOLD (pulling high or disconnecting) shuts down the MAX6767TALD4+ output. HOLD is internally pulled up to OUT with 1.8µA current.
Does the MAX6767TALD4+ support adjustable output voltage?
Yes, the MAX6767TALD4+ supports adjustable output voltage from 1.8V to 11V using an external resistive divider connected to the SET pin. However, the MAX6767TALD4+ variant is configured for fixed 5.0V output (L-suffix), so SET must be connected to GND to select the preset voltage. For adjustable operation, a different suffix (e.g., MAX6767TAJD4+) would be required.
What is the significance of the 'D4' suffix in MAX6767TALD4+?
The 'D4' suffix in MAX6767TALD4+ specifies a factory-programmed reset timeout period of 200ms. This value defines the minimum duration RESET remains asserted after the output voltage recovers above the 4.625V threshold. D4 is one of five standard timeout options (D0–D4), and it meets common automotive microcontroller reset timing requirements defined in ISO 16750-2.
Is the MAX6767TALD4+ qualified for automotive use?
Yes, the MAX6767TALD4+ is AEC-Q100 qualified (Grade 1, -40°C to +125°C), as explicitly stated in the datasheet for MAX6767TA_D_/V+ variants. It includes automotive-specific features: wide 4V–72V input range, load-dump tolerance, thermal shutdown with hysteresis, and guaranteed operation across the full automotive temperature range - making it suitable for body control, telematics, and ADAS applications.
How does the RESET output behave during input voltage transients?
The RESET output on the MAX6767TALD4+ asserts low whenever the regulated OUT voltage falls below 4.625V (L-threshold), including during line transients like cold-crank or load dump recovery. After OUT rises above threshold, RESET remains low for ≥200ms (D4 timeout) before deasserting. This ensures the connected microcontroller receives a clean, extended reset pulse regardless of transient duration, preventing erratic boot behavior.
