Product details
Overview
MAX6758UTWD0+T from Analog Devices is a low-power, single-voltage window detector with factory-trimmed 3.3V nominal monitoring, ±15% adjustable window (SET = VCC/2), active-high push-pull UV output, and 20μs typical reset timeout. It monitors system power supplies in telecom and server applications where precise undervoltage/overvoltage detection with fast response is required.
For engineers reviewing the MAX6758UTWD0+T datasheet, MAX6758UTWD0+T pinout, MAX6758UTWD0+T application, or MAX6758UTWD0+T equivalent, key selection criteria include its 3.3V fixed threshold, ±15% window selectability via SET pin, active-high UV output, 20μs propagation delay, and SOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX6758UTWD0+T implements dual independent comparators with internal reference to detect when VCC falls below UVTH or rises above OVTH. Its SET pin configures hysteresis at ±5%, ±10%, or ±15% - here set to ±15% by biasing to VCC/2. The UV output is active-high push-pull, asserted immediately on undervoltage and deasserted after 20μs once VCC recovers above UVTH.
No latched OV function or dual-supply monitoring is present, distinguishing it from MAX6760–MAX6762 variants. It lacks external voltage divider inputs (UVIN/OVIN), confirming fixed internal threshold architecture per the UTW suffix (3.3V nominal, W = ±15%, D0 = 20μs timeout).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VCC Threshold | 3.3V - factory-trimmed for monitoring standard I/O supply rails |
| Window Tolerance | ±15% - selected via SET pin biased to VCC/2; yields UVTH = 2.805V, OVTH = 3.795V at +25°C |
| Timeout Period | 20μs typ - ensures rapid system recovery after transient brownout without latch delay |
| Supply Current | 13µA typ at 3.6V - enables always-on monitoring in battery-backed or low-power systems |
| Operating Temp Range | -40°C to +125°C - qualified for automotive under-hood and industrial embedded environments |
| Output Type | Active-high push-pull UV - drives high during undervoltage; no external pull-up required |
| VCC Range | 1.0V to 6.0V - supports valid outputs down to 1.0V, enabling operation during deep brownout |
Pinout & Package
MAX6758UTWD0+T is housed in a 6-pin SOT23 package (package code U6+1, outline 21-0058), with thermal resistance θJA = 115°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output drivers |
| 2 | UV | Active-high push-pull undervoltage output; asserts high when VCC < UVTH |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC via 26kΩ resistor |
| 4 | SET | Threshold window select; biased to VCC/2 for ±15% window configuration |
| 5 | VCC | Power supply input and monitored voltage rail; must be ≥1.0V for valid outputs |
| 6 | OV | Active-low open-drain overvoltage output; asserts low when VCC > OVTH; no timeout |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 3.3V threshold | Eliminates external resistor networks; reduces BOM count and layout area for standard I/O rail monitoring |
| ±15% window selectability | Enables robust noise margin tuning via single SET pin bias - critical for noisy DC-DC converter outputs |
| 20μs fast timeout | Supports real-time microprocessor supervision without introducing unnecessary system reset delays |
| Active-high push-pull UV output | Drives high directly into µP NMI or interrupt pin; removes need for external level-shifting or pull-up resistors |
| 10µA ultra-low quiescent current | Permits continuous monitoring in energy-sensitive applications such as smart meters and remote sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar window voltage detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6757UTWD0+T | Active-low push-pull UV output; identical threshold, window, and timing | Requires inverted logic interface (e.g., µP active-low reset input) | Select when interfacing with legacy microcontrollers expecting active-low reset assertion |
| TLV809E33DBZR | Single undervoltage detector only; no overvoltage monitoring or SET-adjustable window | Limited to UV-only use cases; no OV latch or dual-threshold capability | Choose only if system-level OV protection is handled externally (e.g., by separate OVP IC) |
Compared with MAX6757UTWD0+T and TLV809E33DBZR, the MAX6758UTWD0+T uniquely delivers active-high UV signaling with full window detection in one SOT23-6 package - simplifying interface design for modern processors with dedicated NMI inputs.

FAQ
What is the exact undervoltage and overvoltage threshold for MAX6758UTWD0+T at +25°C?
The MAX6758UTWD0+T has a nominal 3.3V threshold with ±15% window (SET = VCC/2), yielding UVTH = 2.805V and OVTH = 3.795V at +25°C. These values are factory-trimmed and guaranteed over -40°C to +125°C with ±0.7% hysteresis. The MAX6758UTWD0+T datasheet Table 1 confirms UTW suffix corresponds to 3.3V nominal, W = ±15%.
Does MAX6758UTWD0+T support dual-voltage monitoring like MAX6760?
No. The MAX6758UTWD0+T monitors only VCC (single supply). Dual-voltage capability (VCC + VCC2) is exclusive to MAX6760–MAX6762 variants. Pinout confirmation shows no VCC2 pin on MAX6758UTWD0+T's SOT23-6 package - only GND, UV, MR, SET, VCC, and OV are present.
Can the SET pin of MAX6758UTWD0+T be left floating?
No. The SET pin must be actively biased to define the window: GND for ±5%, VCC for ±10%, or VCC/2 for ±15%. Floating SET causes undefined threshold behavior. For MAX6758UTWD0+T (UTW), VCC/2 bias is required to achieve the specified ±15% window; a resistor divider from VCC to GND is recommended.
What is the maximum sink current supported by the OV output of MAX6758UTWD0+T?
The OV output of MAX6758UTWD0+T is an active-low open-drain driver rated for 1.4mA sink at VCC ≥ 1.98V, 2.0mA at VCC ≥ 2.75V, and 3.0mA at VCC ≥ 3.63V, with VOL ≤ 0.3V. This allows direct interface with 3.3V logic inputs or pull-up to higher rails. The MAX6758UTWD0+T Electrical Characteristics table specifies these limits under "OV Output Low".
Is MAX6758UTWD0+T AEC-Q100 qualified?
The MAX6758UTWD0+T is not explicitly marked /V (AEC-Q100 qualified) in its part number, but it shares the same die, test flow, and extended temperature range (-40°C to +125°C) as /V variants. Per Analog Devices documentation, /T and /V parts differ only in screening and certification documentation - the MAX6758UTWD0+T silicon is automotive-capable and widely deployed in ADAS modules.
