Product details
Overview
The MAX6758UTZD0 from Maxim Integrated is a single-supply, low-power window voltage detector with independent undervoltage (UV) and overvoltage (OV) push-pull outputs, factory-trimmed 3.3V nominal threshold, ±10% window (3.0V UV / 3.63V OV), 20µs typical propagation delay, and manual reset input - used for reliable microprocessor supply monitoring in industrial DC-DC converter modules.
For engineers reviewing the MAX6758UTZD0 datasheet, MAX6758UTZD0 pinout, MAX6758UTZD0 application, or MAX6758UTZD0 equivalent, key selection criteria include its SOT23-6 package, 10µA supply current, -40°C to +125°C operation, dual-output logic polarity, and compatibility with 1.0V–6.0V VCC supply rails.
Technical Context
The MAX6758UTZD0 implements a precision bandgap reference with comparator-based window detection architecture, where SET pin configuration (connected to VCC) selects ±10% threshold hysteresis. It monitors only VCC (not dual supplies), asserting UV when VCC falls below 3.0V and OV when VCC exceeds 3.63V - both with 20µs response time and no timeout delay on OV.
Its push-pull UV output (active-high) and open-drain OV output (active-low) operate across full VCC range (1.0V–6.0V), with guaranteed logic states down to VCC = 1.0V. The MR input features internal 26kΩ pullup and 4µs minimum pulse width support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VCC Threshold | 3.3V - factory-trimmed for I/O rail monitoring in 3.3V systems |
| UV Threshold (falling) | 3.0V (±10%) - asserts UV output when supply drops below safe operating level |
| OV Threshold (rising) | 3.63V (±10%) - triggers OV output before overvoltage damages downstream circuitry |
| Supply Current | 10µA at 3.6V - enables always-on monitoring in battery-backed or ultra-low-power systems |
| Propagation Delay | 20µs - ensures fast fault response without false triggering on short transients |
| Operating Temp Range | -40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
| VCC Range | 1.0V to 6.0V - supports valid output assertion even during brownout conditions |
Pinout & Package
MAX6758UTZD0 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, Pin 6 is SET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Supply | Powers device and serves as sole monitored voltage rail; outputs remain valid down to 1.0V |
| 2 - GND | Reference Ground | Common return path for all internal references and output drivers |
| 3 - MR | Active-Low Manual Reset | Asserts UV output when pulled low; internal 26kΩ pullup enables button-only interface |
| 4 - UV | Active-High Push-Pull Output | Drives high when VCC < 3.0V or MR is low; sinks up to 2.0mA at VCC ≥ 2.85V |
| 5 - OV | Active-Low Open-Drain Output | Pulls low when VCC > 3.63V; requires external pullup; no timeout delay |
| 6 - SET | Window Hysteresis Select | Connected to VCC for ±10% window; bias to VCC/2 for ±15%; GND for ±5% |
Key Features
| Feature | Design Value |
|---|---|
| Independent UV/OV Outputs | Enables separate system responses - e.g., log undervoltage while immediately disabling power on overvoltage |
| ±10% Factory-Trimmed Window | Eliminates external resistor networks for 3.3V rail monitoring, reducing BOM count and layout area |
| 20µs Propagation Delay | Meets fast-fault requirements in real-time control loops without compromising noise immunity |
| 10µA Quiescent Current | Extends battery life in always-on supervisory applications such as smart sensors and remote meters |
| Manual Reset with Internal Pullup | Reduces external component count by eliminating discrete pullup resistor for reset button interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6757UTZD0 | Same package and thresholds, but UV output is active-low push-pull instead of active-high | Requires inverted logic handling in MCU firmware or external inverter for same functional behavior | Select when existing design uses active-low UV signaling or shares PCB footprint with MAX6757UTZD0 |
| TLV809E33DBZR | Single-output (reset only), fixed 3.3V threshold, no OV detection, no SET pin, 350ms reset timeout | Lacks independent OV flag and adjustable hysteresis; suitable only for basic reset generation, not window monitoring | Choose only if system requires only undervoltage reset and has no overvoltage protection requirement |
Compared with MAX6757UTZD0 and TLV809E33DBZR, the MAX6758UTZD0 uniquely delivers independent, polarity-matched UV/OV outputs with user-selectable hysteresis - essential for safety-critical window monitoring where both fault directions must be distinguished and acted upon separately.

FAQ
What is the exact undervoltage and overvoltage threshold for MAX6758UTZD0?
The MAX6758UTZD0 has a factory-trimmed nominal VCC threshold of 3.3V with ±10% window: undervoltage threshold is 3.0V (falling VCC), and overvoltage threshold is 3.63V (rising VCC). These values are specified over -40°C to +125°C and include 0.7% hysteresis. The SET pin is connected to VCC in this variant to select the ±10% option.
Does MAX6758UTZD0 support dual-voltage monitoring?
No, MAX6758UTZD0 monitors only a single supply (VCC). It belongs to the MAX6757–MAX6759 subgroup, which is designated for single-voltage window detection. Dual-voltage variants like MAX6760–MAX6762 include VCC2 pins and separate monitoring paths - MAX6758UTZD0 lacks VCC2, OVLATCH, and dual-threshold capability.
What output configuration does MAX6758UTZD0 use for UV and OV signals?
MAX6758UTZD0 provides an active-high push-pull UV output (Pin 4) and an active-low open-drain OV output (Pin 5). The UV output drives high when VCC < 3.0V or MR is asserted; the OV output pulls low when VCC > 3.63V and requires an external pullup resistor. This configuration allows independent control of two fault conditions without shared logic states.
Can MAX6758UTZD0 operate with VCC below 1.4V?
Yes, MAX6758UTZD0 guarantees correct output logic states for VCC down to 1.0V, though voltage monitoring functionality requires VCC ≥ 1.4V per datasheet Note 2. Below 1.4V, the internal reference may not be fully stabilized, but asserted outputs (UV high or OV low) remain valid - critical for brownout recovery sequencing in low-voltage systems.
Is the SET pin on MAX6758UTZD0 configurable, and how does it affect thresholds?
Yes, the SET pin (Pin 6) configures hysteresis: connected to VCC for ±10%, to GND for ±5%, or biased to VCC/2 for ±15%. For MAX6758UTZD0, the "Z" suffix confirms SET is tied to VCC, yielding 3.0V/3.63V thresholds. This eliminates external resistors and ensures repeatable window width across production lots and temperature.
