Analog Devices Inc./Maxim Integrated MAX6765TTLD2/V+T

Overview

MAX6765TTLD2/V+T from Maxim Integrated is an automotive-grade micropower linear regulator with integrated supervisor, delivering 5.0V at up to 100mA from 4V–72V input. It features a fixed 5V output (L-suffix), 4.625V reset threshold (D2 suffix = 12.5ms timeout), open-drain active-low RESET, and AEC-Q100 qualification for under-hood modules requiring ultra-low quiescent current (31µA) and thermal robustness.

For engineers reviewing the MAX6765TTLD2/V+T datasheet, MAX6765TTLD2/V+T pinout, MAX6765TTLD2/V+T application, or MAX6765TTLD2/V+T equivalent, this page provides verified technical context, validated pin functions, confirmed automotive operating range (-40°C to +125°C), and real-world selection guidance for always-on power management in harsh environments.

Technical Context

The MAX6765TTLD2/V+T implements a single-enable, fixed-output linear regulator architecture with internal 1.233V reference and precision bandgap-controlled feedback. Its supervisor block monitors OUT voltage against a factory-trimmed 4.625V reset threshold and asserts an open-drain RESET signal for a fixed 12.5ms timeout after recovery - set by internal D2 configuration, not external capacitor.

It integrates overtemperature shutdown (160°C trip, 20°C hysteresis), short-circuit protection, and output overvoltage protection (107–113% of VOUT). The ENABLE input is internally pulled down (0.6µA sink), supporting direct connection to automotive ignition signals without external biasing.

Key Specifications

Pinout & Package

MAX6765TTLD2/V+T uses a thermally enhanced 3mm × 3mm, 6-pin TDFN-EP package (package code T633+2) with exposed pad (EP) electrically connected to GND for optimal thermal dissipation. Pin 1 is marked by dot; EP must be soldered to PCB ground plane.

FAQ

What is the exact reset threshold voltage and timeout for MAX6765TTLD2/V+T?

The MAX6765TTLD2/V+T has a factory-trimmed reset threshold of 4.625V (±125mV) and a fixed reset timeout period of 12.5ms (D2 option), guaranteed over -40°C to +125°C. This is confirmed in Table 2 of the datasheet and applies specifically to the L-suffix (5V output) and D2-suffix (12.5ms) configuration of MAX6765TTLD2/V+T.

Does MAX6765TTLD2/V+T require external components to set its 5V output?

No. MAX6765TTLD2/V+T delivers a factory-trimmed 5.0V output (L-suffix) without any external resistors. The SET pin is internally connected to GND for fixed-output mode. Only bypass capacitors - ≥0.1µF at IN and ≥10µF at OUT - are required for stable operation of MAX6765TTLD2/V+T.

Is the RESET output of MAX6765TTLD2/V+T push-pull or open-drain?

The RESET output of MAX6765TTLD2/V+T is open-drain, active-low. It requires an external pullup resistor to the host system's logic rail (e.g., 3.3V or 5V) to generate a valid high-level signal. This is explicitly defined in the Pin Description table and Functional Diagram for MAX6765/MAX6766 variants like MAX6765TTLD2/V+T.

Can MAX6765TTLD2/V+T operate with input voltage below 4V?

No. MAX6765TTLD2/V+T has a minimum specified input voltage of 4V per Absolute Maximum Ratings and Electrical Characteristics tables. Operation below 4V is not guaranteed - dropout voltage and regulation performance degrade rapidly, and the device may cease regulation or assert RESET. Always maintain VIN ≥ 4V for reliable MAX6765TTLD2/V+T operation.

What is the thermal performance of MAX6765TTLD2/V+T in a standard PCB layout?

On a 4-layer PCB with adequate copper pour, MAX6765TTLD2/V+T achieves θJA = 42°C/W. At 100mA load and 14V input, power dissipation is ~0.62W, resulting in ~26°C junction-to-ambient rise - well within the -40°C to +125°C operating range. The exposed pad (EP) must be soldered to a solid ground plane to realize this thermal performance for MAX6765TTLD2/V+T.
