Product details
Overview
The MAX6754UKZD0+T from Analog Devices is a low-power, single-supply window voltage detector monitoring 2.5V system supplies with ±5% factory-trimmed thresholds (UVTH = 2.25V–2.375V, OVTH = 2.625V–2.75V), 20μs typical reset timeout, push-pull RESET output, and manual reset input - used in DC-DC converter modules and telecom power rails for reliable brownout/overvoltage fault signaling.
For engineers reviewing the MAX6754UKZD0+T datasheet, MAX6754UKZD0+T pinout, MAX6754UKZD0+T application, or MAX6754UKZD0+T equivalent, key selection criteria include its SOT23-5 package, 10μA supply current, -40°C to +125°C operation, fixed 2.5V nominal monitoring, and D0 (20μs) timeout option - critical for fast-response microprocessor supervision in automotive and industrial power systems.
Technical Context
The MAX6754UKZD0+T implements a precision bandgap reference with internal resistor-divider network to set fixed 2.5V nominal thresholds, combined with comparator-based UV/OV detection logic and a 20μs propagation delay path. Its SET pin is hardwired to GND (per Z suffix) to configure ±5% window hysteresis.
It features an active-low manual reset (MR) input with 26kΩ internal pullup, push-pull RESET output with guaranteed VOL ≤ 0.3V at ISINK = 100μA, and operates down to VCC = 1.0V while maintaining valid output states - enabling robust supervision of low-voltage digital rails during startup and brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Supply Voltage | 2.5V - Factory-trimmed to monitor 2.5V system rail with ±5% window (Z suffix) |
| Undervoltage Threshold | 2.25V to 2.375V (falling VCC) - Triggers RESET assertion below this range |
| Overvoltage Threshold | 2.625V to 2.75V (rising VCC) - Triggers RESET assertion above this range |
| Reset Timeout Period | 20μs typ - Fast deassertion after VCC recovers into valid window |
| Supply Current | 13μA typ at VCC = 3.6V - Enables ultra-low-power always-on monitoring |
| Operating Temperature | -40°C to +125°C - Qualified for under-hood automotive and industrial environments |
| Output Type | Active-low push-pull RESET - Drives directly into µP reset pin without external pullup |
| Package | SOT23-5 (U5+1) - 2.9mm × 1.6mm footprint, compatible with high-density PCB layouts |
Pinout & Package
SOT23-5 package (Outline 21-0057, Land Pattern 90-0174), 5-pin surface-mount device with exposed pad not present. Pin 1 = VCC, Pin 2 = GND, Pin 3 = MR, Pin 4 = RESET, Pin 5 = SET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Voltage | Supplies device and serves as primary monitored rail; requires 0.1µF bypass capacitor to GND |
| 2 - GND | Ground Reference | Common return for all internal circuitry and output drivers |
| 3 - MR | Active-Low Manual Reset Input | Asserts RESET when pulled low; internally pulled up to VCC via 26kΩ resistor |
| 4 - RESET | Active-Low Push-Pull Output | Drives µP reset pin directly; sinks 100μA with VOL ≤ 0.3V |
| 5 - SET | Window Threshold Select | Connected to GND (Z suffix) to fix ±5% window; no external bias required |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Trimmed 2.5V Window Detection | Eliminates external resistor networks and calibration; supports immediate deployment on 2.5V I/O rails |
| 20μs Typical Reset Timeout | Enables rapid system recovery after transient dips - critical for real-time control loops |
| 10μA Supply Current | Reduces standby power in battery-backed or energy-harvested systems by >50% vs. legacy supervisors |
| Valid Outputs Down to VCC = 1.0V | Ensures deterministic reset behavior during deep brownout, preventing latch-up or undefined states |
| ±5% Threshold Accuracy Over Temperature | Maintains tight window across -40°C to +125°C without trimming - verified per AEC-Q100 stress tests |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar window voltage detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6754UKZD3+T | Same 2.5V ±5% thresholds but 100ms min timeout period instead of 20μs | Suitable for slower power-up sequences where extended reset hold is required | Select MAX6754UKZD3+T only if system firmware requires ≥100ms reset assertion after power-on |
| TLV809E25DBZR | Single-channel 2.5V supervisor with 140ms reset timeout, no SET pin or manual reset | Lacks MR input and adjustable window; simpler but less flexible for field-recovery use cases | Choose TLV809E25DBZR for cost-sensitive, non-recoverable applications where manual reset is unnecessary |
Compared with MAX6754UKZD3+T and TLV809E25DBZR, the MAX6754UKZD0+T uniquely delivers sub-100μs response with manual reset capability - making it optimal for real-time systems requiring both speed and serviceability.

FAQ
What is the exact undervoltage and overvoltage threshold range for MAX6754UKZD0+T?
The MAX6754UKZD0+T has a factory-trimmed 2.5V nominal supply with ±5% window (Z suffix). Its undervoltage threshold (UVTH) is 2.25V to 2.375V (falling VCC), and overvoltage threshold (OVTH) is 2.625V to 2.75V (rising VCC), specified over -40°C to +125°C. These values are confirmed in the Electrical Characteristics table of the MAX6754–MAX6764 datasheet (Rev 12, p.3).
Does MAX6754UKZD0+T support manual reset functionality?
Yes, the MAX6754UKZD0+T includes an active-low manual reset (MR) input (Pin 3). Driving MR low asserts the RESET output regardless of VCC level. The output remains asserted for 300ns after MR rises, then deasserts after the 20μs timeout. MR is internally pulled up to VCC via a 26kΩ resistor, eliminating need for external components.
What package type and footprint does MAX6754UKZD0+T use?
The MAX6754UKZD0+T uses a 5-pin SOT23 package (package code U5+1, outline 21-0057, land pattern 90-0174). It measures 2.9mm × 1.6mm × 1.1mm and is RoHS-compliant. No exposed pad is present - simplifying thermal design and reflow profile setup for high-volume manufacturing.
Can MAX6754UKZD0+T operate with supply voltages below 2.5V?
Yes, the MAX6754UKZD0+T operates from VCC = 1.0V to 6.0V and maintains valid RESET output states down to 1.0V. However, its internal 2.5V window detection is only functional when VCC ≥ 1.4V (per datasheet Note 2). Below 1.4V, outputs remain latched in their last valid state - ensuring safe shutdown behavior during deep brownout.
Is MAX6754UKZD0+T qualified for automotive applications?
The MAX6754UKZD0+T is not explicitly AEC-Q100 qualified, as that certification applies only to /V-suffixed variants (e.g., MAX6754UKZD0/V+T). However, it shares the same silicon, SOT23-5 package, and -40°C to +125°C operating range, and is widely deployed in automotive ADAS and body electronics where full qualification is not mandated.
