Product details
Overview
The MAX6754UKWD3+ from Analog Devices is a low-power, single-supply window voltage detector monitoring 1.8V system supplies with ±15% factory-trimmed thresholds (UVTH = 1.530V, OVTH = 2.070V), 100ms minimum reset timeout, active-low open-drain RESET output, and manual reset input - used in DC-DC converter modules to prevent microprocessor operation during out-of-spec rail conditions.
For engineers reviewing the MAX6754UKWD3+ datasheet, MAX6754UKWD3+ pinout, MAX6754UKWD3+ application, or MAX6754UKWD3+ equivalent, key selection criteria include its 100ms reset timeout, ±15% window tolerance, 10μA supply current, -40°C to +125°C operation, and SOT23-5 package compatibility with space-constrained power management circuits.
Technical Context
The MAX6754UKWD3+ implements a fixed-threshold window detection architecture with internal bandgap reference and comparator-based UV/OV sensing. It uses a SET pin biased to VCC/2 to configure ±15% hysteresis around the nominal 1.8V supply, enabling robust rejection of short transients while maintaining accurate trip points across temperature.
Its open-drain RESET output asserts low when VCC falls below 1.530V or rises above 2.070V, with deassertion delayed by ≥100ms after recovery. The MR input provides active-low manual reset with 4μs minimum pulse width and internal 26kΩ pullup, ensuring deterministic system initialization independent of supply ramp rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0V to 6.0V - supports valid output assertion down to 1.0V VCC, enabling brownout detection even during deep undervoltage events |
| Undervoltage Threshold | 1.530V (min) at TA = -40°C to +125°C - factory-trimmed for 1.8V nominal supply with ±15% window |
| Overvoltage Threshold | 2.070V (max) at TA = -40°C to +125°C - matches 1.8V × 1.15 for precise overvoltage protection |
| Reset Timeout Period | 100ms (min) - ensures stable microprocessor reset hold time after supply recovery |
| Supply Current | 13μA (typ) at VCC = 3.6V - enables battery-backed or ultra-low-power monitoring applications |
| Operating Temperature | -40°C to +125°C - qualified for automotive under-hood and industrial embedded environments |
| Output Type | Open-drain RESET - allows wired-OR configuration and level translation with external pullup |
Pinout & Package
MAX6754UKWD3+ is housed in a 5-pin SOT23 package (package code U5+1), with exposed pad not present. Pin functions are validated per Maxim Integrated datasheet Rev 12 (2022).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Supply | Primary power rail input and the voltage being monitored; must be ≥1.0V for functional outputs |
| 2 - GND | Ground Reference | Analog and digital ground return; requires low-impedance connection to system ground plane |
| 3 - MR | Manual Reset Input | Active-low signal with internal 26kΩ pullup to VCC; 4μs minimum pulse width required for reliable assertion |
| 4 - RESET | Reset Output | Open-drain output asserted low during UV/OV fault; requires external pullup resistor for logic-level interface |
| 5 - SET | Window Threshold Select | Bias to VCC/2 (e.g., via resistor divider) to configure ±15% window; GND = ±5%, VCC = ±10% |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Trimmed 1.8V Window Detection | Eliminates external resistor networks and calibration effort for 1.8V rail monitoring |
| ±15% Adjustable Window Tolerance | SET pin biasing enables precise trade-off between noise immunity and trip-point margin |
| 100ms Minimum Reset Timeout | Guarantees sufficient hold time for microprocessor core stabilization post-power recovery |
| 10μA Typical Supply Current | Reduces quiescent load on backup batteries or energy-harvesting power sources |
| Manual Reset with Internal Pullup | Enables pushbutton-initiated system reset without external components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar window voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809KDBZR | Single undervoltage detector only (no overvoltage function); 1.6V threshold; 200ms reset timeout; SOT23-3 package | Lacks window detection capability - requires separate OV circuit for full rail supervision | Select when only UV monitoring is needed and board space is constrained to 3-pin footprint |
| ADM6315-23ARTZ-RL7 | Fixed 2.32V UV detector with 200ms timeout; no OV detection; push-pull output; same SOT23-5 package | Monitors higher voltage rail; no window functionality or SET-adjustable tolerance | Choose for cost-sensitive 2.3V systems where ±15% window flexibility is unnecessary |
Compared with TLV809KDBZR and ADM6315-23ARTZ-RL7, the MAX6754UKWD3+ uniquely delivers integrated UV/OV window detection with user-selectable ±15% tolerance in the same SOT23-5 footprint, reducing component count and PCB area for 1.8V rail supervision.

FAQ
What is the exact undervoltage and overvoltage threshold for MAX6754UKWD3+?
The MAX6754UKWD3+ has factory-trimmed thresholds for a nominal 1.8V supply: undervoltage threshold (UVTH) is 1.530V (min) and overvoltage threshold (OVTH) is 2.070V (max), corresponding to ±15% window tolerance across -40°C to +125°C. These values are specified in the Electrical Characteristics table of the MAX6754–MAX6764 datasheet Rev 12.
Does MAX6754UKWD3+ support manual reset, and what are its timing requirements?
Yes, MAX6754UKWD3+ includes an active-low manual reset (MR) input with internal 26kΩ pullup to VCC. It requires a minimum pulse width of 4μs and exhibits 300ns propagation delay from MR falling edge to RESET assertion. The asserted state persists for ≥100ms after MR returns high, matching the device's reset timeout period.
What package type and pin count does MAX6754UKWD3+ use?
MAX6754UKWD3+ is packaged in a 5-pin SOT23 (package code U5+1), with pinout: 1=VCC, 2=GND, 3=MR, 4=RESET (open-drain), 5=SET. This compact footprint measures 2.9mm × 1.6mm × 1.1mm and is RoHS-compliant with lead-free finish.
Can MAX6754UKWD3+ monitor voltages other than 1.8V?
No - MAX6754UKWD3+ is factory-trimmed specifically for 1.8V nominal supply monitoring. Its suffix "W" denotes 1.8V, and "D3" specifies 100ms timeout. Other variants (e.g., "T"=3.3V, "L"=5V) exist in the MAX6754 family, but MAX6754UKWD3+ is fixed to 1.8V with ±15% window.
Is MAX6754UKWD3+ qualified for automotive applications?
MAX6754UKWD3+ operates over -40°C to +125°C and meets extended temperature requirements for automotive under-hood use, but it is not AEC-Q100 qualified. Only /V-suffixed parts in the MAX6754–MAX6764 family (e.g., MAX6754UKWD3/V) carry AEC-Q100 qualification; MAX6754UKWD3+ is intended for industrial and telecom applications.
