Analog Devices Inc./Maxim Integrated MAX6754UKTD0+T

Overview

The MAX6754UKTD0+T from Analog Devices is a low-power, single-supply window voltage detector that monitors 3.3V system supplies for undervoltage (UV) and overvoltage (OV) conditions with ±10% factory-trimmed thresholds, 20μs typical response time, and active-low push-pull RESET output. It features manual reset input (MR), SET pin for window selection, operates from 1.0V to 6.0V supply, and is qualified for automotive-grade extended temperature range (-40°C to +125°C).

For engineers reviewing the MAX6754UKTD0+T datasheet, MAX6754UKTD0+T pinout, MAX6754UKTD0+T application, or MAX6754UKTD0+T equivalent, this device serves as a precision, low-quiescent-current (13–30µA) power-supply supervisor in telecom, server, and automotive power-rail monitoring where fast fault detection and reliable reset assertion are required.

Technical Context

The MAX6754UKTD0+T implements a fixed-threshold window detection architecture using an internal bandgap reference and comparator circuitry. It compares VCC against factory-trimmed UVTH (2.805V min, 2.970V max) and OVTH (3.630V min, 3.795V max) thresholds at 3.3V nominal, with ±10% window set via SET = VCC connection.

It provides a single combined RESET output that asserts low on either UV or OV violation, deasserts after 20μs timeout (D0 suffix), and supports manual reset assertion via MR pin with 300ns propagation delay and internal 26kΩ pull-up. No latching or dual-voltage monitoring is implemented - it is strictly a single-VCC, single-output window detector.

Key Specifications

FAQ

What is the exact undervoltage and overvoltage threshold range for MAX6754UKTD0+T at 3.3V nominal?

The MAX6754UKTD0+T has factory-trimmed thresholds for 3.3V nominal supply: undervoltage threshold (UVTH) is 2.805V (min) to 2.970V (max), and overvoltage threshold (OVTH) is 3.630V (min) to 3.795V (max), corresponding to a ±10% window centered at 3.3V. These values are guaranteed over -40°C to +125°C per datasheet Rev 12.

Does MAX6754UKTD0+T support manual reset, and what are its timing characteristics?

Yes, MAX6754UKTD0+T includes an active-low manual reset (MR) input with internal 26kΩ pull-up to VCC. MR assertion forces immediate RESET output low; after MR release, RESET remains asserted for 300ns (propagation delay tD-MR) before deassertion. This enables precise, externally initiated system reset for diagnostics or recovery.

What package type and pin count does MAX6754UKTD0+T use, and is it RoHS-compliant?

MAX6754UKTD0+T uses a 5-pin SOT23-5 package (outline 21-0057, land pattern 90-0174) with RoHS-compliant "+" suffix in its package code (U5+1). It has no exposed pad. Thermal resistance θJA is 324.3°C/W (single-layer board) and 255.9°C/W (multi-layer board), supporting compact PCB layouts in thermally constrained applications.

Can MAX6754UKTD0+T monitor voltages other than 3.3V?

No - MAX6754UKTD0+T is factory-trimmed exclusively for 3.3V nominal supply monitoring. The "T" suffix in the part number denotes 3.3V; other variants (e.g., "L" = 5V, "Z" = 2.5V) exist but are distinct orderable parts. For adjustable thresholds, consider MAX6763/MAX6764 instead.

What is the supply current consumption of MAX6754UKTD0+T, and how does it vary with voltage?

MAX6754UKTD0+T draws 13–30µA typical supply current at VCC = 3.6V, with ICC remaining stable across 1.0V–6.0V per typical operating curves. At 1.8V, ICC is ~15µA; at 5V, it is ~25µA. This ultra-low quiescent current enables use in always-on, battery-backed supervisory circuits without significant drain.
