Product details
Overview
MAX6758UTLD3 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), 100ms minimum reset timeout, and manual reset input - used in microprocessor power monitoring for industrial embedded systems.
For engineers reviewing the MAX6758UTLD3 datasheet, MAX6758UTLD3 pinout, MAX6758UTLD3 application, or MAX6758UTLD3 equivalent, this device delivers precise dual-threshold detection with guaranteed output validity down to VCC = 1.0V, immunity to short transients (<300ns), and operation across -40°C to +125°C for automotive-grade reliability.
Technical Context
The MAX6758UTLD3 implements a dual-comparator architecture with internal reference and adjustable hysteresis (0.7%), where SET pin selection (connected to VCC) configures ±10% window tolerance around its fixed 3.3V nominal threshold. It monitors only VCC - not dual supplies - and asserts UV high / OV low on violation, with no timeout on OV but 100ms min timeout on UV/reset recovery.
Its MR input is internally pulled up to VCC (26kΩ), requires ≥4µs pulse width, and triggers propagation delays of 300ns (D0) or 100–320ms (D3) depending on timeout option. Output drive capability supports ISINK = 2.0mA at VCC ≥ 2.85V (VOL ≤ 0.3V) and ISOURCE = 0.8mA (VOH ≥ 0.8×VCC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VCC Threshold | 3.3V - factory-trimmed for I/O supply monitoring in 3.3V systems |
| Undervoltage Threshold (UVTH) | 3.0V (min, falling VCC) - triggers UV output high when supply drops below 3.0V |
| Overvoltage Threshold (OVTH) | 3.63V (max, rising VCC) - triggers OV output low when supply exceeds 3.63V |
| Timeout Period | 100ms min - ensures stable reset release after UV condition clears |
| Supply Current (ICC) | 13µA typ at VCC = 3.6V - enables battery-backed or ultra-low-power applications |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial environments |
| Output Type | Push-pull UV and OV - eliminates external pull-up resistors, reduces BOM count |
Pinout & Package
MAX6758UTLD3 is housed in a 6-pin SOT23-6 package with exposed pad (not connected), optimized for space-constrained PCB layouts and thermal performance in high-density designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Supply | Powers device and serves as the single monitored voltage rail (3.3V nominal) |
| 2 - GND | Ground Reference | Common return path for internal comparators, reference, and outputs |
| 3 - MR | Active-Low Manual Reset Input | Drives UV high and OV low when pulled low; internal 26kΩ pull-up to VCC |
| 4 - UV | Active-High Push-Pull Undervoltage Output | Asserts high when VCC < 3.0V; deasserts after 100ms timeout when VCC recovers |
| 5 - SET | Window Tolerance Select | Connected to VCC for ±10% window (3.0V/3.63V); GND = ±5%, bias = ±15% |
| 6 - OV | Active-Low Push-Pull Overvoltage Output | Asserts low immediately when VCC > 3.63V; no timeout - fast fault response |
Key Features
| Feature | Design Value |
|---|---|
| Independent UV/OV outputs | Enables separate system responses to brownout vs. overvoltage events without logic gating |
| ±10% factory-set window (3.3V) | Eliminates external resistor networks while maintaining tight 3.0V–3.63V detection range |
| 100ms minimum reset timeout | Prevents premature processor restart during slow-rising power rails or transient dips |
| Low 13µA supply current | Extends battery life in always-on monitoring circuits and enables use in energy-harvesting nodes |
| VCC = 1.0V output validity | Guarantees correct UV/OV logic states even during deep brownout, critical for safe shutdown sequencing |
| 300ns transient immunity | Rejects ESD and switching noise spikes without false triggering, reducing need for additional filtering |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6757UTLD3 | Active-low UV output (vs. MAX6758UTLD3's active-high UV) | Requires inverted logic handling in host MCU GPIO or external inverter | Select when legacy design uses active-low reset signaling or shares reset bus with other active-low devices |
| TLV809E33DBZR | Single-output (reset only), no independent OV, ±2% accuracy, no SET pin | Lacks overvoltage detection and window adjustability; only provides basic undervoltage reset | Choose for cost-sensitive, single-threshold applications where OV monitoring is unnecessary |
Compared with MAX6757UTLD3, MAX6758UTLD3 simplifies interface design by eliminating level inversion; compared with TLV809E33DBZR, it adds critical overvoltage protection and configurable window tolerance - essential for robust power domain supervision.

FAQ
What is the exact undervoltage and overvoltage threshold for MAX6758UTLD3?
The MAX6758UTLD3 has a factory-trimmed nominal VCC threshold of 3.3V with ±10% window tolerance. Its undervoltage threshold (UVTH) is 3.0V (min, falling VCC), and overvoltage threshold (OVTH) is 3.63V (max, rising VCC), both specified over -40°C to +125°C. These values are confirmed in the Electrical Characteristics table under "T, 3.3V" suffix conditions.
Does MAX6758UTLD3 support dual-voltage monitoring?
No, MAX6758UTLD3 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 - MAX6758UTLD3 lacks VCC2 and OVLATCH functionality.
What output configuration does MAX6758UTLD3 use for UV and OV?
MAX6758UTLD3 features active-high push-pull UV output and active-low push-pull OV output. This eliminates external pull-up resistors, reduces power consumption, and ensures fast, rail-to-rail logic transitions. The UV output goes high during undervoltage, and OV goes low during overvoltage - both with guaranteed VOL ≤ 0.3V and VOH ≥ 0.8×VCC.
How does the SET pin function on MAX6758UTLD3?
On MAX6758UTLD3, the SET pin selects window tolerance: connected to VCC for ±10% (3.0V/3.63V), to GND for ±5%, or biased to VCC/2 for ±15%. This pin configures internal comparator reference scaling and is fully compatible with standard logic levels - no external biasing components required for the ±10% default configuration.
Is MAX6758UTLD3 qualified for automotive applications?
Yes, MAX6758UTLD3 is specified for -40°C to +125°C operation and offered in lead-free SOT23-6 packaging compliant with AEC-Q100 stress testing requirements. While not explicitly labeled "automotive grade" in its part number (lacking /V suffix), its temperature range, transient immunity (300ns), and output validity down to VCC = 1.0V meet core functional safety needs for body electronics and non-safety-critical power domains.
