Product details
Overview
MAX6769TASD2+T from Maxim Integrated is an automotive-grade micropower linear regulator with integrated supervisor and adjustable reset threshold. It operates from 4V to 72V input, delivers up to 100mA output at 3.3V, features open-drain active-low RESET with 12.5ms fixed timeout (D2 suffix), and supports RESETIN-based monitoring of external voltages-ideal for engine control units requiring robust brownout detection.
For engineers reviewing the MAX6769TASD2+T datasheet, MAX6769TASD2+T pinout, MAX6769TASD2+T application, or MAX6769TASD2+T equivalent, key selection criteria include its 3.3V fixed output, 2.888V RESETIN threshold (S variant), 12.5ms reset timeout, AEC-Q100 qualification, and TDFN-6 package with exposed pad for thermal management in high-ambient automotive environments.
Technical Context
The MAX6769TASD2+T implements a high-voltage linear regulation architecture with internal 1.233V reference and precision resistive divider feedback via SET pin. Its RESETIN input enables monitoring of external supply rails using a user-defined voltage divider, with threshold set by VTH = 1.085V (S variant) and scaled by external R3/R4.
It integrates dual supervision functions: output-voltage monitoring with fixed 2.888V reset threshold (for 3.3V OUT), and independent RESETIN monitoring with programmable threshold; both assert the same open-drain RESET output after a 12.5ms timeout following fault clearance. Thermal shutdown activates at +160°C with 20°C hysteresis.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Bypass with ≥0.1µF capacitor; withstands -0.3V to +80V transient stress. |
| 2 GND | Ground Reference | Primary return path; EP must be connected to same ground plane for thermal performance. |
| 3 ENABLE | Active-High Enable | Pulled low internally (0.6µA); requires >1.4V to activate regulator; compatible with 3.3V/5V logic. |
| 4 RESET | Active-Low Open-Drain Reset Output | Sinks 3.2mA max; requires external pullup; asserts when OUT or RESETIN falls below threshold. |
| 5 TIMEOUT | Reset Timeout Adjust | Connected to OUT for 12.5ms fixed timeout (D2); floating or cap-to-GND alters timing. |
| 6 OUT | Regulated Output | 3.3V @ 100mA; bypass with ≥10µF capacitor; protected against short-circuit and overtemperature. |
Key Features

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 |
|---|---|---|---|
| MAX6770TASD2+T | Same pinout and electrical specs, but includes HOLD input for self-holding circuit implementation. | Required where ignition-switch-controlled latching behavior is needed without external components. | Select MAX6770TASD2+T only if HOLD functionality is required; otherwise MAX6769TASD2+T offers identical core regulation and supervision at lower cost. |
| TLV70733PDQNR | Lower input range (2.5V–5.5V), no RESETIN, no AEC-Q100, 200mA output, SOT-23-5 package. | Limited to infotainment or low-voltage auxiliary rails-not suitable for direct battery connection or automotive qualification. | Use TLV70733PDQNR only for non-automotive, low-voltage subsystems; MAX6769TASD2+T remains mandatory for primary 12V/24V automotive rails. |
Compared with MAX6770TASD2+T, MAX6769TASD2+T removes HOLD functionality to reduce complexity and cost while retaining identical regulation, RESET, and RESETIN supervision-making it optimal for standard enable-controlled ECUs. Compared with TLV70733PDQNR, MAX6769TASD2+T provides 4× wider input range, AEC-Q100 compliance, and dual-rail monitoring essential for functional safety.

FAQ
What is the exact reset timeout period for MAX6769TASD2+T?
The MAX6769TASD2+T has a fixed reset timeout period of 12.5ms, indicated by the "D2" suffix in its part number. This timeout begins when the monitored voltage (either OUT or RESETIN) rises above its respective threshold and ensures the RESET output remains asserted for the full duration, satisfying boot timing requirements of automotive microcontrollers such as NXP S32K and ST STM32G4 series.
Does MAX6769TASD2+T support adjustable output voltage?
No, MAX6769TASD2+T provides a fixed 3.3V output. The "T" in the part number denotes the 3.3V output option. While the broader MAX6767–MAX6774B family supports adjustable outputs via the SET pin, the MAX6769 variant uses internal feedback resistors and requires SET to be grounded-no external resistor network is used or supported for voltage adjustment in MAX6769TASD2+T.
How is the RESETIN threshold configured on MAX6769TASD2+T?
The MAX6769TASD2+T uses the "S" suffix to specify a RESETIN threshold of 2.888V, derived from its internal 1.085V reference (VTH) and a fixed scaling ratio. No external resistors are needed-the threshold is factory-trimmed and fixed. This allows direct monitoring of a 3.3V rail with ~12.5% undervoltage margin, eliminating external divider design effort while ensuring consistent brownout detection across temperature.
Is MAX6769TASD2+T qualified for automotive use?
Yes, MAX6769TASD2+T is AEC-Q100 qualified (Grade 1) and rated for -40°C to +125°C operation. Its qualification covers stress testing for temperature cycling, humidity, mechanical shock, and ESD-ensuring reliability in under-hood and chassis-mounted automotive applications. The "/V+" designation in related ordering codes confirms automotive qualification, and MAX6769TA_D_/V+ variants are explicitly listed in the datasheet as qualified.
What package type and thermal performance does MAX6769TASD2+T use?
MAX6769TASD2+T uses a 3mm × 3mm, 6-pin TDFN-EP package (outline 21-0137) with exposed pad. On a multilayer PCB, it achieves θJA = 42°C/W and θJC = 9°C/W, enabling 1.9W continuous power dissipation at +70°C ambient. The exposed pad must be soldered to a solid ground plane to realize full thermal performance-critical for sustained 100mA operation in high-temperature automotive environments.
