Product details
Overview
MAX6759UTLD0+T from Analog Devices is a low-power, single-voltage window detector monitoring 3.3V system supplies with ±5% threshold window (UVTH = 2.97V–3.135V, OVTH = 3.465V–3.63V), 20μs propagation delay, active-low open-drain UV and OV outputs, and manual reset input - used in telecom power sequencing and server voltage supervision.
For engineers reviewing the MAX6759UTLD0+T datasheet, MAX6759UTLD0+T pinout, MAX6759UTLD0+T application, or MAX6759UTLD0+T equivalent, key selection criteria include factory-trimmed 3.3V monitoring, independent UV/OV outputs, SOT23-6 package compatibility, -40°C to +125°C operation, and 10μA supply current at 3.6V.
Technical Context
The MAX6759UTLD0+T implements dual independent comparators with internal reference and hysteresis (0.7%), configured for fixed 3.3V nominal monitoring (T-suffix) and ±5% window (L-suffix). Its SET pin is internally biased to GND, enabling precise undervoltage/overvoltage detection without external resistors.
It features open-drain UV and OV outputs with no timeout on assertion, a manual reset (MR) input with 26kΩ internal pullup, and guaranteed output validity down to VCC = 1.0V - supporting brownout recovery in low-voltage microprocessor systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0V to 6.0V - enables operation during deep brownout while maintaining valid output states |
| UV Threshold (3.3V nominal) | 2.97V to 3.135V (falling VCC, ±5%) - triggers reset when 3.3V rail drops below safe logic margin |
| OV Threshold (3.3V nominal) | 3.465V to 3.63V (rising VCC, ±5%) - protects downstream circuitry from overvoltage stress |
| Supply Current | 13μA typical at 3.6V - minimizes quiescent load in always-on power monitor circuits |
| Propagation Delay | 20μs typical - ensures fast fault response for real-time power integrity monitoring |
| Operating Temperature | -40°C to +125°C - qualified for automotive under-hood and industrial embedded environments |
| Output Type | Independent open-drain UV and OV - allows flexible pullup to different voltage domains or wired-OR fault aggregation |
Pinout & Package
MAX6759UTLD0+T is housed in a 6-pin SOT23 package (U6+1 code, outline 21-0058), optimized for space-constrained PCB layouts with thermal resistance θJA = 115°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground Reference | Primary return path for internal comparators and bias circuitry; must be low-impedance connection |
| 2 - UV | Undervoltage Output | Active-low open-drain signal asserted when VCC falls below UVTH; requires external pullup |
| 3 - MR | Manual Reset Input | Active-low control with 26kΩ internal pullup to VCC; initiates immediate UV assertion on falling edge |
| 4 - SET | Window Select Input | Internally tied to GND for ±5% window configuration; no external components required |
| 5 - OV | Overvoltage Output | Active-low open-drain signal asserted when VCC exceeds OVTH; no timeout, immediate deassertion on recovery |
| 6 - VCC | Power & Monitor Input | Supplies device and serves as monitored voltage rail; bypass with 0.1μF capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 3.3V window detection | Eliminates external resistor networks and calibration effort for standard I/O rail monitoring |
| Independent UV and OV outputs | Enables separate fault handling - e.g., UV triggers soft reset, OV triggers shutdown sequence |
| 20μs fast propagation delay | Meets tight timing budgets in high-speed processor power-up sequences and dynamic voltage scaling |
| 10μA ultra-low supply current | Extends battery life in portable test equipment and always-on supervisory circuits |
| Open-drain outputs with 4mA sink capability | Supports level-shifting and direct interface to 1.8V/2.5V/3.3V logic families via appropriate pullup |

Equivalent & Alternatives
The following parts are listed as comparable options for similar window detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6758UTLD0+T | Active-high push-pull UV output instead of open-drain; identical thresholds, timing, and pinout | Requires no external pullup; incompatible with wired-OR fault bus architectures | Select when driving CMOS inputs directly without level translation or shared fault lines |
| TLV809E33DBZR | Single UV reset IC only (no OV detection); 3.08V threshold, 200ms reset timeout, SOT23-3 package | Lacks overvoltage protection and independent OV output; smaller footprint but functionally incomplete replacement | Choose only if system-level OV monitoring is handled elsewhere and board space is critical |
Compared with MAX6758UTLD0+T and TLV809E33DBZR, the MAX6759UTLD0+T uniquely delivers independent open-drain UV/OV outputs with factory-set 3.3V ±5% window in SOT23-6 - essential for fault-isolation-critical telecom and server designs requiring dual-rail violation reporting.

FAQ
What is the exact undervoltage and overvoltage threshold range for MAX6759UTLD0+T?
The MAX6759UTLD0+T has a factory-trimmed 3.3V nominal monitoring point with ±5% window. Its undervoltage threshold (UVTH) is 2.97V to 3.135V (falling VCC), and overvoltage threshold (OVTH) is 3.465V to 3.63V (rising VCC), specified over -40°C to +125°C. These values are confirmed in the Electrical Characteristics table for T-suffix, L-suffix, D0-option devices in the MAX6754–MAX6764 datasheet.
Does MAX6759UTLD0+T require external resistors to set its voltage thresholds?
No. The MAX6759UTLD0+T uses factory-laser-trimmed internal dividers for its 3.3V nominal thresholds. The SET pin is internally connected to GND to configure the ±5% window, eliminating need for external resistors or calibration. This is confirmed in the Pin Description and Detailed Description sections of the datasheet.
What output configuration does MAX6759UTLD0+T use for UV and OV signals?
The MAX6759UTLD0+T provides independent active-low open-drain outputs for both UV and OV. Each output requires an external pullup resistor to the desired logic voltage domain. This configuration is explicitly stated in the Pin Description table and Functional Diagrams for MAX6757–MAX6759 variants.
Can MAX6759UTLD0+T operate reliably at VCC = 1.2V?
Yes. The MAX6759UTLD0+T guarantees correct output logic states (UV and OV) for VCC down to 1.0V, though voltage monitoring functionality requires VCC ≥ 1.4V per datasheet Note 2. At 1.2V, outputs remain asserted/deasserted as appropriate, enabling brownout-safe reset hold during recovery - confirmed in Absolute Maximum Ratings and Electrical Characteristics tables.
Is MAX6759UTLD0+T qualified for automotive applications?
The MAX6759UTLD0+T itself is not AEC-Q100 qualified; only /V-suffix variants (e.g., MAX6759UTLD0/V) carry that qualification. However, it operates across -40°C to +125°C and meets key automotive transient immunity specs (300ns immunity), making it suitable for non-safety-critical ADAS subsystems where full qualification is not mandated.
