Product details
Overview
The MAX6755UKWD0+ from Maxim Integrated is a low-power, single-voltage window detector with factory-trimmed 1.8V nominal supply monitoring, ±15% adjustable window (via SET pin), active-high push-pull RESET output, and 20µs typical timeout period. It asserts RESET when VCC falls below 1.62V or rises above 2.07V (at +25°C), operates from 1.0V to 6.0V supply, draws only 13µA at 3.6V, and targets microprocessor power-rail supervision in space-constrained industrial and telecom systems.
For engineers reviewing the MAX6755UKWD0+ datasheet, MAX6755UKWD0+ pinout, MAX6755UKWD0+ application, or MAX6755UKWD0+ equivalent, key selection criteria include its fixed 1.8V monitoring point, ±15% window selectability, 20µs fast response, push-pull active-high RESET drive capability, and SOT23-5 package compatibility with high-density PCB layouts.
Technical Context
This device implements a precision bandgap reference with comparator-based undervoltage/overvoltage detection on a single monitored rail (VCC). Its internal threshold divider is factory-trimmed for 1.8V nominal operation (suffix 'W'), and the SET pin selects ±5%, ±10%, or ±15% window width by biasing to GND, VCC, or VCC/2 respectively.
The RESET output is push-pull and active-high, asserting when VCC breaches either threshold and deasserting after a 20µs timeout once VCC returns within the window. No manual reset (MR) or latched OV function is present - consistent with the MAX6755 series' single-output, non-latching architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VCC Threshold | 1.8V - factory-trimmed detection point for core or I/O supply monitoring |
| Window Tolerance | ±15% - selected via SET = VCC/2; yields UVTH = 1.53V / OVTH = 2.07V at +25°C |
| Timeout Period | 20µs typ - enables rapid system recovery after transient voltage excursions |
| Supply Current | 13µA typ at 3.6V - supports always-on supervision in battery-backed or low-power systems |
| Operating Range | -40°C to +125°C - qualified for extended-temperature industrial and automotive environments |
| Output Type | Active-high push-pull RESET - drives logic-high directly without external pull-up |
| VCC Operating Range | 1.0V to 6.0V - ensures valid output states even during brownout down to 1.0V |
Pinout & Package
MAX6755UKWD0+ is housed in a 5-pin SOT23-5 package with exposed pad not connected (non-TDFN variant). Pin 1 is VCC, Pin 2 is GND, Pin 3 is MR (not used in MAX6755 per functional diagram), Pin 4 is RESET, and Pin 5 is SET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Rail | Supplies device and serves as the voltage under supervision; must be bypassed with 0.1µF capacitor to GND |
| 2 - GND | Ground Reference | Common return path for all internal circuitry and output drivers |
| 3 - MR | Manual Reset Input | Not functional in MAX6755 - unused pin; leave unconnected or tie to VCC/GND per layout best practice |
| 4 - RESET | Active-High Push-Pull Output | Drives high when VCC is within window; drives low when VCC violates UV/OV thresholds |
| 5 - SET | Window Width Select | Bias to VCC/2 (e.g., resistor divider) to configure ±15% window; no external components needed for fixed bias |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Trimmed 1.8V Threshold | Eliminates external resistor networks for precise 1.8V rail monitoring in FPGA, DSP, or ASIC core supplies |
| ±15% Adjustable Window | Enables robust tolerance margining against ripple, load transients, and temperature drift without redesign |
| 20µs Fast Timeout | Supports high-speed digital systems requiring sub-millisecond reset assertion/deassertion timing |
| 13µA Ultra-Low ICC | Permits continuous supervision in energy-sensitive applications like remote sensors or backup controllers |
| Push-Pull Active-High RESET | Directly interfaces with CMOS inputs without pull-up resistors, reducing BOM count and board area |
Applications
| Industrial PLC I/O Module | Telecom Line Card Power Supervision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809EADL30DBVR | Fixed 3.0V threshold, no window adjustment, open-drain output, 140ms reset timeout | Only suitable for 3.0V rails; requires external pull-up; slower response limits use in high-speed systems | Select when cost sensitivity outweighs need for adjustability and speed |
| ADM6315-29DARTZ-RL | Fixed 2.93V threshold, ±2.5% accuracy, push-pull output, 200ms timeout, -40°C to +105°C range | Lacks window configuration; narrower temp range excludes extended-temperature industrial use | Choose for legacy designs already using ADM6315 footprint and timing profile |
Compared with TLV809EADL30DBVR and ADM6315-29DARTZ-RL, the MAX6755UKWD0+ uniquely delivers ±15% window adjustability at 1.8V with 20µs speed and full -40°C to +125°C operation - enabling tighter tolerance control and faster fault response in next-generation embedded systems.

FAQ
What is the exact undervoltage and overvoltage threshold for MAX6755UKWD0+ at +25°C?
The MAX6755UKWD0+ has a factory-trimmed nominal VCC threshold of 1.8V. With SET biased to VCC/2 for ±15% window, its undervoltage threshold (UVTH) is 1.53V and overvoltage threshold (OVTH) is 2.07V at +25°C, as specified in the Electrical Characteristics table under "W, 1.8V" row with "SET = VCC/2" condition.
Does MAX6755UKWD0+ support manual reset functionality?
No, the MAX6755UKWD0+ does not implement manual reset. Pin 3 (MR) is not functional in this variant - it is reserved from the MAX6754–MAX6756 family's shared pinout but unused. The device relies solely on automatic VCC monitoring and RESET assertion based on threshold violations.
What package type and dimensions does MAX6755UKWD0+ use?
The MAX6755UKWD0+ is packaged in a 5-pin SOT23-5 (also labeled SOT-23) with body dimensions of 2.9mm × 1.6mm × 1.1mm (L × W × H) and lead pitch of 0.95mm. It does not include an exposed pad; the package is RoHS-compliant and lead(Pb)-free, indicated by the "+" suffix.
Can MAX6755UKWD0+ monitor voltages below 1.0V?
No. The MAX6755UKWD0+ requires VCC ≥ 1.0V to operate, and its outputs remain asserted in correct logic state only down to 1.0V. Monitoring of sub-1.0V rails (e.g., 0.9V, 0.75V) is not supported - the lowest factory-trimmed option in this family is 0.9V (suffix 'E'), but that applies to other variants like MAX6754UKED0+, not MAX6755UKWD0+.
Is MAX6755UKWD0+ qualified for automotive applications?
The MAX6755UKWD0+ is not automotive-qualified. Only parts with "/V" suffix (e.g., MAX6755UKWD0+/V) are AEC-Q100 qualified. This variant carries the "+" suffix indicating lead(Pb)-free RoHS compliance only, and is rated for industrial temperature range (-40°C to +125°C), not automotive grade.
