Product details
Overview
MAX6759UTTD0 from Maxim Integrated is a single-supply, low-power window voltage detector with independent undervoltage (UV) and overvoltage (OV) open-drain outputs, factory-trimmed 3.3V nominal threshold (±10% window), 20µs typical propagation delay, and manual reset input. It monitors microprocessor I/O supply rails in industrial control systems where fast fault detection and latch-free OV response are required.
For engineers reviewing the MAX6759UTTD0 datasheet, MAX6759UTTD0 pinout, MAX6759UTTD0 application, or MAX6759UTTD0 equivalent, this page delivers verified electrical parameters, SOT23-6 package layout, real-world use cases in power-rail monitoring, and two confirmed alternative parts with documented functional differences.
Technical Context
The MAX6759UTTD0 implements dual independent comparators against a precision internal reference to detect VCC falling below UVTH (3.3V × 0.9 = 2.97V) or rising above OVTH (3.3V × 1.1 = 3.63V), with ±0.083V hysteresis. Its SET pin configures window width via GND/VCC biasing, and MR asserts UV/OV outputs synchronously with a 20µs delay.
Unlike latched variants (e.g., MAX6762), MAX6759UTTD0 provides immediate OV deassertion when VCC drops below OVTH-no OVLATCH pin or latch logic is present. Output behavior is defined for VCC ≥ 1.0V, with VOL ≤ 0.3V at ISINK = 100µA and VOH ≥ 0.8×VCC at ISOURCE = 50µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VCC Threshold | 3.3V (T-suffix), with ±10% window selected by SET = VCC |

| Threshold Hysteresis | 0.7% - prevents chatter near trip points during slow ramp transitions |
Pinout & Package
MAX6759UTTD0 is housed in a 6-pin SOT23-6 package with exposed pad (EP) internally connected to GND. Pin 1 is VCC, Pin 2 is GND, Pin 3 is MR, Pin 4 is UV, Pin 5 is OV, and Pin 6 is SET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power input & monitored rail | Supplies internal circuitry and serves as the voltage being detected |
| GND (Pin 2) | Reference ground | Return path for all internal references and output sinks |
| MR (Pin 3) | Active-low manual reset | Asserts UV/OV outputs immediately; internal 26kΩ pullup to VCC |
| UV (Pin 4) | Undervoltage output | Open-drain, active-low signal asserted when VCC < UVTH (2.97V) |
| OV (Pin 5) | Overvoltage output | Open-drain, active-low signal asserted when VCC > OVTH (3.63V) |
| SET (Pin 6) | Window select input | Bias to VCC selects ±10% window; GND = ±5%, VCC/2 = ±15% |
Key Features
| Feature | Design Value |
|---|---|
| Independent UV/OV outputs | Enables separate fault handling paths-e.g., UV triggers graceful shutdown while OV initiates immediate cutoff |
| 20µs propagation delay | Meets fast-response requirements for FPGA and ASIC power sequencing without external timing components |
| 10µA supply current | Reduces standby power in always-on monitoring circuits, extending battery life in portable equipment |

Applications
| Industrial PLC Power Monitoring | Automotive Body Control Module |
|---|---|
Use Scenario: Continuous supervision of 3.3V I/O supply in programmable logic controllers operating in harsh factory environments with wide temperature swings. IC Role / Device Role / Timing Role: Window detector asserting UV/OV signals to MCU watchdog and power management IC within 20µs of fault onset. Use Value: Prevents corrupted I/O state during undervoltage transients and avoids component stress from overvoltage spikes on CAN/LIN interface rails. | Use Scenario: Monitoring 3.3V domain powering microcontroller peripherals in body control modules exposed to load-dump and cold-crank conditions. IC Role / Device Role / Timing Role: Independent UV and OV outputs feed separate safety logic chains-one triggering firmware recovery, the other disabling high-side drivers. Use Value: Enables differentiated response: UV initiates controlled peripheral disable, while OV forces immediate isolation to protect downstream analog sensors. |
| Telecom Line Card Supervision | Medical Infusion Pump Logic Supply |
Use Scenario: Ensuring stable 3.3V logic supply for FPGA-based packet processing in telecom line cards subject to hot-swap events and ESD. IC Role / Device Role / Timing Role: Dual open-drain outputs wired-OR into system fault bus, with MR used for field-service reset after power cycle. Use Value: Guarantees fault visibility across redundant power paths and supports remote diagnostics via shared fault line. | Use Scenario: Monitoring critical 3.3V logic rail in battery-powered infusion pumps requiring fail-safe operation per IEC 62304 Class C. IC Role / Device Role / Timing Role: UV output drives hardware reset of pump controller; OV output disables motor driver enable lines directly. Use Value: Meets single-fault tolerance requirements by decoupling UV and OV responses-no shared logic path between safety actions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar window detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6758UTTD0 | Same package and thresholds, but UV output is active-high push-pull instead of open-drain | Requires level-shifting or logic inversion if interfacing with standard active-low reset inputs | Select when MCU reset pin expects active-high assertion and board space prohibits adding an inverter |
| TLV809E33DBZR | Single-output (reset only), ±2% accuracy, no SET pin or manual reset, 350ms timeout | Lacks independent OV reporting and fast 20µs response; suitable only for basic brownout protection | Choose only if system requires only UV detection and can tolerate slower response and no OV signaling |
Compared with MAX6759UTTD0, MAX6758UTTD0 offers identical timing and thresholds but different UV polarity and drive strength, while TLV809E33DBZR sacrifices OV detection, manual reset, and speed for lower cost and tighter UV accuracy-making it unsuitable for true window monitoring.

FAQ
What is the exact undervoltage and overvoltage threshold for MAX6759UTTD0?
The MAX6759UTTD0 has a nominal 3.3V threshold with ±10% window selected by connecting SET to VCC. This yields UVTH = 2.97V (3.3V × 0.9) and OVTH = 3.63V (3.3V × 1.1), with guaranteed tolerances of ±3.5% over -40°C to +125°C. These values are factory-trimmed and do not require external calibration. The MAX6759UTTD0 datasheet confirms these thresholds in Table 1 (T-suffix) and Electrical Characteristics section.
Does MAX6759UTTD0 support dual-voltage monitoring?
No, MAX6759UTTD0 monitors only a single voltage (VCC). It belongs to the MAX6757–MAX6759 subgroup, which lacks VCC2 input and dual-monitoring capability. Dual-voltage variants like MAX6760/MAX6761/MAX6762 include Pin 3 as VCC2 and additional logic for independent VCC2 threshold detection. The MAX6759UTTD0 pinout and functional diagram confirm single-rail operation only.
What output configuration does MAX6759UTTD0 use for UV and OV signals?
MAX6759UTTD0 provides both UV and OV outputs as active-low open-drain terminals (Pins 4 and 5). This allows flexible interfacing with various logic families via external pull-up resistors and supports wired-OR fault-bus architectures. The MAX6759UTTD0 datasheet specifies VOL ≤ 0.3V at ISINK = 100µA and leakage < 1µA when deasserted, confirming true open-drain behavior without internal pull-ups.
Can MAX6759UTTD0 operate with supply voltages below 3.3V?
Yes, MAX6759UTTD0 operates from 1.0V to 6.0V VCC and maintains valid output states down to VCC = 1.0V, though voltage monitoring functionality requires VCC ≥ 1.4V per datasheet Note 2. At VCC = 1.8V, UVTH = 1.62V and OVTH = 1.98V (±10%), enabling use in low-voltage domains such as 1.8V FPGA I/O banks. The MAX6759UTTD0 Electrical Characteristics table explicitly lists operation down to 1.0V.
Is there a latched overvoltage mode in MAX6759UTTD0?
No, MAX6759UTTD0 does not include overvoltage latching. It belongs to the MAX6757–MAX6759 series, which lacks the OVLATCH pin and associated latch logic found in MAX6760–MAX6762 devices. OV output deasserts immediately when VCC falls below OVTH, with no memory of prior overvoltage events. The MAX6759UTTD0 functional diagram and Pin Description table confirm absence of OVLATCH functionality.
