Product details
Overview
MAX6765TTLD2+T from Maxim Integrated is an automotive-grade 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, and a 12.5ms fixed reset timeout (D2 suffix), designed for always-on vehicle modules such as body control units and infotainment power rails.
For engineers reviewing the MAX6765TTLD2+T datasheet, MAX6765TTLD2+T pinout, MAX6765TTLD2+T application, or MAX6765TTLD2+T equivalent, key selection criteria include its AEC-Q100 qualification, thermally enhanced 3mm × 3mm TDFN-6 package, -40°C to +125°C operation, and compatibility with automotive battery transient conditions (up to +80V absolute max VIN).
Technical Context
The MAX6765TTLD2+T implements a single-enable, fixed-output linear regulator architecture with internal 1.233V reference and precision bandgap-controlled feedback. Its supervisor block includes an open-drain active-low RESET output with factory-set 4.625V threshold (L-suffix) and fixed 12.5ms timeout via internal timing circuitry-no external capacitor required.
This variant belongs to the MAX6765–MAX6774B family's base enable-mode group (ENABLE-only, no HOLD/WDI/RESETIN), supporting standard ignition-switched power sequencing. It lacks watchdog timer, dual enable, or adjustable output functionality-confirmed by pinout (6-pin TDFN) and ordering code structure (TTLD2 = 5V, L-threshold, D2 timeout).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 72V - supports full automotive battery range including cold-crank (4V) and load-dump (72V) transients. |
| Output Voltage | 5.0V ±1.5% - factory-trimmed fixed output; meets microcontroller I/O rail requirements without external feedback components. |
| Quiescent Current | 31µA typical - enables >10-year battery standby life in always-on modules like telematics or alarm systems. |
| Dropout Voltage | 620mV at 100mA - ensures regulation down to VIN = 5.62V, critical during low-battery cranking conditions. |
| Reset Threshold | 4.625V (L option) - asserts RESET when VOUT drops below 92.5% of nominal, preventing MCU brownout execution errors. |
| Reset Timeout | 12.5ms (D2 option) - guarantees minimum reset pulse width for reliable µP initialization after power recovery. |
| Operating Temperature | -40°C to +125°C - fully specified for under-hood and cabin-mounted automotive applications. |
Pinout & Package
MAX6765TTLD2+T uses a thermally enhanced 6-pin TDFN-EP (3mm × 3mm, package code T633+2) with exposed pad (EP) connected internally to GND for optimal thermal dissipation (θJC = 9°C/W). The EP must be soldered to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Bypassed to GND with ≥0.1µF ceramic capacitor; withstands -0.3V to +80V absolute max. |
| 2 GND | Ground Reference | Primary return path for regulator and supervisor circuits; connects to EP for thermal conduction. |
| 3 ENABLE | Active-High Enable | Drives high to activate regulator; internally pulled down (0.6µA) for default-off safety. |
| 4 RESET | Active-Low Open-Drain Output | Sinks 3.2mA max; requires external pull-up to VCC or µP VDD for proper reset signaling. |
| 5 TIMEOUT | Reset Timeout Configuration | Connected to OUT internally for fixed 12.5ms timeout (D2); floating or tied to GND disables adjustment. |
| 6 OUT | Regulated Output | 5.0V supply rail; bypassed to GND with ≥10µF capacitor; protected against short-circuit and overtemperature. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Rated for automotive use (-40°C to +125°C), qualified per stress test requirements for reliability in harsh environments. |
| Low Quiescent Current | 31µA enables <10µA system sleep current when paired with MCU-controlled ENABLE sequencing. |
| Integrated Supervisor | Combines precise reset generation (4.625V threshold, 12.5ms timeout) with regulator in single die-eliminates discrete supervisor IC. |
| Thermal Protection | Shuts down at +160°C junction temp with 20°C hysteresis, enabling safe operation during sustained high-power dissipation. |
| Robust Input Rating | Withstands +80V absolute maximum input-covers ISO 7637-2 Pulse 5a load-dump events without external clamping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6765TTLD4+T | Same 5V/4.625V/Dx family; 200ms reset timeout instead of 12.5ms. | Suitable where longer reset hold time is needed for complex firmware initialization sequences. | Select when µP boot time exceeds 12.5ms and requires extended reset assertion. |
| TLV73350PDBVR | Lower voltage range (1.4V–5.5V), 300mA output, no supervisor, no AEC-Q100 rating. | Non-automotive, low-input applications only; lacks reset, thermal shutdown, and high-voltage capability. | Only viable for cost-sensitive industrial designs with stable 5V input and no safety or supervision requirements. |
Compared with MAX6765TTLD4+T, the MAX6765TTLD2+T provides faster system recovery after brownout; compared with TLV73350PDBVR, it delivers automotive-grade robustness, integrated supervision, and 72V input tolerance-making it irreplaceable in battery-connected vehicle electronics.

FAQ
What is the reset threshold voltage for MAX6765TTLD2+T?
The MAX6765TTLD2+T has a fixed reset threshold of 4.625V (L-suffix), meaning the active-low RESET output asserts when the regulated 5.0V output falls below this value. This threshold is factory-trimmed and guaranteed over -40°C to +125°C, providing precise brownout detection for automotive microcontrollers without external resistor networks.
Does MAX6765TTLD2+T include a watchdog timer?
No, the MAX6765TTLD2+T does not include a watchdog timer. Watchdog functionality is exclusive to MAX6773/MAX6773B/MAX6774/MAX6774B variants (denoted by WDI pin). The MAX6765TTLD2+T belongs to the base enable-mode family with ENABLE, RESET, and TIMEOUT pins only-confirmed by its 6-pin TDFN package and ordering code structure.
What package type and thermal performance does MAX6765TTLD2+T use?
MAX6765TTLD2+T uses a 3mm × 3mm TDFN-6 package with exposed pad (T633+2), rated for 1.905W continuous power dissipation at +70°C ambient. Its thermal resistance is θJA = 42°C/W (multi-layer board) and θJC = 9°C/W, enabling reliable operation at 100mA load under high ambient temperatures common in automotive under-hood locations.
Can MAX6765TTLD2+T be used with adjustable output voltages?
No, MAX6765TTLD2+T provides only a fixed 5.0V output. Adjustable output capability (1.8V–11V) requires SET pin functionality, which is absent in MAX6765/MAX6766 variants. The "TTLD2" suffix explicitly denotes fixed 5V (T), L-threshold (4.625V), and D2 timeout (12.5ms)-no SET pin is present, and pin 6 is dedicated solely to the fixed-output OUT terminal.
Is MAX6765TTLD2+T AEC-Q100 qualified?
Yes, MAX6765TTLD2+T is AEC-Q100 qualified. The "/V+" suffix in the full ordering code (MAX6765TTLD2+/V+) confirms automotive qualification. It is fully specified over -40°C to +125°C, includes overtemperature and short-circuit protection, and meets stress testing requirements for automotive electronic control units.
