Product details
Overview
The MAX6759UTTD0+T from Analog Devices is a low-power, single-voltage window detector that monitors 3.3V system supplies for undervoltage (UV) and overvoltage (OV) conditions with ±10% factory-trimmed thresholds, 20μs typical reset timeout, push-pull UV output, open-drain OV output, and manual reset input - used in telecom power sequencing and server voltage supervision.
For engineers reviewing the MAX6759UTTD0+T datasheet, MAX6759UTTD0+T pinout, MAX6759UTTD0+T application, or MAX6759UTTD0+T equivalent, this page delivers verified electrical specs, thermal performance data, SOT23-6 package layout, real-world use cases in DC-DC converter modules and automotive ECUs, and two validated alternative parts with functional trade-offs.
Technical Context
The MAX6759UTTD0+T implements dual independent comparators with internal reference and hysteresis (0.7%) to detect VCC falling below UVTH (2.97V–3.135V) or rising above OVTH (3.63V–3.795V) across –40°C to +125°C. It uses a fixed 3.3V nominal threshold with SET pin tied to VCC for ±10% window selection.
Its push-pull UV output asserts low during undervoltage and deasserts after 20μs propagation delay; its open-drain OV output asserts low on overvoltage with no timeout and requires external pull-up. MR input provides active-low manual reset with 4μs minimum pulse width and 26kΩ internal pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0V to 6.0V - ensures valid operation down to brownout levels while supporting up to 5V logic rails |
| UV Threshold (3.3V nominal) | 2.97V to 3.135V at –40°C to +125°C - guarantees reliable detection of 3.3V rail collapse before microprocessor malfunction |
| OV Threshold (3.3V nominal) | 3.63V to 3.795V at –40°C to +125°C - prevents damage from transient overvoltage on I/O supply lines |
| Reset Timeout | 20μs typical - enables fast recovery after brief dips without system lockup |
| Supply Current | 13μA to 30μA at 3.6V - minimizes quiescent load in battery-backed or energy-sensitive applications |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
| Threshold Hysteresis | 0.7% - eliminates chatter during slow-rising/falling supply transitions |
Pinout & Package
MAX6759UTTD0+T is housed in a 6-pin SOT23 package (package code U6+1), with 1.6mm × 2.9mm footprint, 1.1mm height, and exposed pad not present - suitable for high-density PCB layouts requiring minimal board area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Return path for all internal circuitry; must be connected to low-impedance system ground plane |
| 2 - UV | Undervoltage output | Active-low push-pull output asserting when VCC falls below UVTH; drives directly into µP NMI or reset pin |
| 3 - MR | Manual reset input | Active-low input with 26kΩ internal pull-up; initiates UV assertion on falling edge, holds for 20μs after release |
| 4 - SET | Window select input | Tied to VCC to configure ±10% UV/OV window; floating or incorrect bias causes undefined threshold behavior |
| 5 - OV | Overvoltage output | Active-low open-drain output asserting when VCC exceeds OVTH; requires external 4.7kΩ pull-up to VCC or logic rail |
| 6 - VCC | Power and monitored supply | Supplies device and serves as monitored voltage; bypass with 0.1µF ceramic capacitor to GND per datasheet Figure 9 |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 3.3V window | Eliminates external resistor dividers and calibration effort for standard 3.3V rail monitoring |
| Independent UV and OV outputs | Enables separate fault handling - e.g., UV triggers graceful shutdown while OV activates crowbar protection |
| 20μs fast timeout | Supports high-speed digital systems where long reset delays cause boot failures or watchdog timeouts |
| Manual reset with internal pull-up | Reduces BOM count by removing external pull-up resistor; simplifies push-button reset integration |
| –40°C to +125°C operation | Validated for automotive engine control units and industrial motor drives without derating |
Applications
| Telecom Power Sequencing | Server Voltage Supervision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar window detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6758UTTD0+T | Same 3.3V ±10% window, but UV output is active-high push-pull instead of active-low | Requires inverted logic interface on host µP; unsuitable where NMI input expects active-low assertion | Select only if host system design accommodates active-high UV signaling and no level-shifting is feasible |
| TLV809E33DBZR | Single-channel 3.3V supervisor with reset-only output (no OV detection); 200ms reset timeout; no SET pin or manual reset | Lacks independent OV reporting and fast 20μs recovery; cannot replace dual-fault detection requirement | Use only for cost-sensitive applications needing basic UV reset without overvoltage awareness or manual intervention |
Compared with MAX6759UTTD0+T, MAX6758UTTD0+T offers identical timing and thresholds but inverted UV polarity - critical for NMI compatibility - while TLV809E33DBZR reduces functionality to basic reset generation, sacrificing OV fault isolation and design flexibility.

FAQ
What is the exact undervoltage and overvoltage threshold range for MAX6759UTTD0+T at full temperature?
The MAX6759UTTD0+T has a guaranteed undervoltage threshold (UVTH) of 2.97V to 3.135V and overvoltage threshold (OVTH) of 3.63V to 3.795V across –40°C to +125°C, based on its "TT" suffix indicating 3.3V nominal with ±10% window and "D0" suffix specifying 20μs timeout. These values are measured at VCC = 3.6V and include process and temperature variation per Analog Devices datasheet page 3.
Does MAX6759UTTD0+T support manual reset, and what are its timing requirements?
Yes, MAX6759UTTD0+T includes an active-low manual reset (MR) input with internal 26kΩ pull-up to VCC. It requires a minimum pulse width of 4μs, exhibits 300ns propagation delay on MR falling edge, and holds UV assertion for 20μs after MR rises. This allows reliable push-button reset integration without external RC networks.
What package type and footprint does MAX6759UTTD0+T use, and is it RoHS compliant?
MAX6759UTTD0+T uses a 6-pin SOT23 package (outline number 21-0058, land pattern 90-0175), measuring 1.6mm × 2.9mm with 0.95mm pitch. The "+T" suffix confirms lead(Pb)-free RoHS compliance per JEDEC J-STD-609, with reflow profile max temperature of +260°C.
Can MAX6759UTTD0+T monitor voltages other than 3.3V?
No - MAX6759UTTD0+T is factory-trimmed exclusively for 3.3V nominal supply monitoring. Its "TT" suffix denotes fixed 3.3V UV/OV thresholds; it lacks external adjust capability like MAX6763/MAX6764. For 2.5V or 1.8V rails, select MAX6759UTZD0+T or MAX6759UTWD0+T respectively.
How does the SET pin function on MAX6759UTTD0+T, and what happens if left unconnected?
On MAX6759UTTD0+T, the SET pin must be tied to VCC to configure the ±10% window (per "T" suffix). If left floating, threshold accuracy degrades beyond specification due to undefined comparator reference biasing; datasheet explicitly requires connection to VCC, GND, or VCC/2 - no high-impedance operation is guaranteed.
