Product details
Overview
The MAX6754UKTD3+T from Analog Devices is a low-power, single-supply window voltage detector monitoring 3.3V system supplies with ±10% factory-trimmed thresholds (UVTH = 2.805–2.970V, OVTH = 3.630–3.795V), 100ms minimum reset timeout, active-low push-pull RESET output, and manual reset input - used in telecom power sequencing and server rail supervision.
For engineers reviewing the MAX6754UKTD3+T datasheet, MAX6754UKTD3+T pinout, MAX6754UKTD3+T application, or MAX6754UKTD3+T equivalent, key selection criteria include its 100ms timeout period, ±10% window accuracy over –40°C to +125°C, 10µA supply current at 3.6V, SOT23-5 package, and compatibility with 1.0V–6.0V VCC operation.
Technical Context
This device implements a precision internal bandgap reference with comparator-based UV/OV detection logic, fixed 3.3V nominal threshold scaling, and SET-pin-controlled ±10% window selection. It features propagation delay of 20µs (typ) and guaranteed output assertion for VCC ≥ 1.0V.
The MAX6754UKTD3+T integrates a 26kΩ internal MR pullup, supports manual reset assertion with 4µs minimum pulse width, and delivers push-pull RESET output with VOL ≤ 0.3V at ISINK = 100µA - enabling direct interface with microprocessor NMI inputs without external pullups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Supply Voltage | 3.3V - matches common I/O rail; enables direct monitoring without external dividers |
| Undervoltage Threshold (UVTH) | 2.805V–2.970V (–40°C to +125°C) - ensures reliable brownout detection before CPU lockup |
| Overvoltage Threshold (OVTH) | 3.630V–3.795V (–40°C to +125°C) - protects downstream logic from overvoltage stress |
| Reset Timeout Period | 100ms min - meets JEDEC JESD8-15A hold-time requirements for 3.3V systems |
| Supply Current (ICC) | 13µA typ at 3.6V - enables always-on monitoring in battery-backed subsystems |
| Operating Temperature | –40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Output Type | Active-low push-pull RESET - eliminates need for external pullup resistor on µP NMI line |
Pinout & Package
MAX6754UKTD3+T is housed in a 5-pin SOT23-5 package (package code U5+1A, outline 21-0057), with exposed pad not present. Thermal resistance θJA = 255.9°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Voltage | Supplies device and serves as primary monitored rail; valid down to 1.0V for output assertion |
| 2 - GND | Ground Reference | Common return for all internal comparators and output drivers; requires low-impedance connection |
| 3 - MR | Active-Low Manual Reset Input | Internally pulled up to VCC via 26kΩ; asserts RESET when pulled below 0.23×VCC for ≥4µs |
| 4 - RESET | Active-Low Push-Pull Output | Drives low to notify µP of fault; deasserts after 100ms timeout once VCC returns within window |
| 5 - SET | Window Select Input | Connected to VCC to configure ±10% window; no external bias required |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar window voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6754UKTD0+T | 20µs typical reset timeout instead of 100ms minimum; identical thresholds and pinout | Suitable for fast-recovery systems where immediate re-enabling is required after brief dips | Select when timing-critical real-time control loops demand sub-100µs response rather than guaranteed hold time |
| TLV809E33DBZR | Single undervoltage detector only (no overvoltage function); 3.3V threshold, open-drain output, 140ms timeout | Lacks OV detection and push-pull drive; requires external pullup and separate OV circuitry | Choose only if overvoltage protection is handled elsewhere and cost minimization outweighs functional completeness |
Compared with MAX6754UKTD0+T and TLV809E33DBZR, the MAX6754UKTD3+T uniquely delivers combined UV/OV window detection with guaranteed 100ms reset hold time and integrated push-pull drive - eliminating external components and simplifying fault-handling firmware.

FAQ
What is the operating voltage range for the MAX6754UKTD3+T?
The MAX6754UKTD3+T operates from VCC = 1.0V to 6.0V. Its outputs remain asserted in the correct logic state down to 1.0V, though voltage monitoring functionality requires VCC ≥ 1.4V per datasheet Note 2. This allows safe fault signaling even during deep brownout conditions where the MAX6754UKTD3+T itself remains functional.
How does the SET pin configure the window for the MAX6754UKTD3+T?
For the MAX6754UKTD3+T, the SET pin is connected to VCC to select a ±10% window around the nominal 3.3V threshold. This configures UVTH = 2.805–2.970V and OVTH = 3.630–3.795V across temperature. No external biasing is needed - the internal architecture interprets VCC-level SET as the ±10% option per the device's suffix "T" and "D3" coding.
Does the MAX6754UKTD3+T provide separate UV and OV outputs?
No, the MAX6754UKTD3+T provides a single combined RESET output that asserts low when VCC falls below UVTH *or* rises above OVTH. It belongs to the MAX6754–MAX6756 subgroup, which uses a unified output architecture - unlike the MAX6757–MAX6764 series that offer independent UV and OV pins. The RESET pin serves both fault conditions.
What is the reset timeout behavior of the MAX6754UKTD3+T after a fault clears?
The MAX6754UKTD3+T holds the RESET output low for a minimum of 100ms after VCC rises above UVTH (for undervoltage recovery) or drops below OVTH (for overvoltage recovery). This timeout is guaranteed across temperature and supply voltage, with typical values of 185ms and maximum of 320ms - ensuring sufficient hold time for microprocessor initialization sequences.
Is the MAX6754UKTD3+T compatible with manual reset push-button circuits?
Yes, the MAX6754UKTD3+T supports manual reset via its MR pin, which is internally pulled up to VCC through a 26kΩ resistor. Driving MR low for ≥4µs asserts RESET. A simple RC-debounced push button to ground suffices - no external pullup required. The device guarantees proper MR response down to VCC = 1.0V, making it suitable for systems with weak or decaying backup supplies.
