Product details
Overview
The MAX6755UKZD0+T from Analog Devices is a low-power, single-supply window voltage detector that monitors 2.5V system supplies with ±5% threshold accuracy (UVTH = 2.25V–2.375V, OVTH = 2.625V–2.75V), features active-high push-pull RESET output, 20μs typical propagation delay, and operates from -40°C to +125°C in SOT23-5 package. It serves as a system power supervisor in telecom DC-DC modules.
For engineers reviewing the MAX6755UKZD0+T datasheet, MAX6755UKZD0+T pinout, MAX6755UKZD0+T application, or MAX6755UKZD0+T equivalent, key selection criteria include factory-trimmed 2.5V monitoring, ±5% window setting via SET pin grounded, 10μA supply current, and compatibility with microprocessor reset sequencing requiring fast undervoltage/overvoltage response.
Technical Context
The MAX6755UKZD0+T implements a precision bandgap reference with comparator-based UV/OV detection circuitry, where VCC (2.5V nominal) is both power source and monitored rail. Its internal SET logic interprets GND connection as ±5% window, enabling fixed-threshold operation without external resistors.
It uses a single-stage reset timeout architecture with 20μs propagation delay (D0 suffix), no latching, and manual reset input (MR) with 26kΩ internal pullup. Output assertion is push-pull active-high RESET, valid down to VCC = 1.0V, ensuring reliable reset signaling during brownout recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Supply Voltage | 2.5V - Factory-trimmed for direct monitoring of 2.5V rails without external scaling |
| Window Accuracy | ±5% - Achieved by grounding SET pin; defines UVTH = 2.25V–2.375V and OVTH = 2.625V–2.75V at TA = -40°C to +125°C |
| Supply Current | 13µA typ at VCC = 3.6V - Enables battery-backed or ultra-low-power system supervision |
| Propagation Delay | 20µs typ - Ensures rapid fault detection and reset assertion for real-time power integrity |
| Operating Temperature | -40°C to +125°C - Qualified for automotive under-hood and industrial embedded environments |
| Output Type | Active-high push-pull RESET - Drives microprocessor RESET pin directly without external pullup |
| Reset Timeout | 20µs typ - No minimum delay; deasserts immediately after VCC returns within window |
Pinout & Package
MAX6755UKZD0+T is housed in a 5-pin SOT23-5 package (package code U5+1), with exposed pad not present. Pin functions are validated per MAX6755 functional diagram and pin description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Rail | Supplies device and serves as the 2.5V voltage being supervised; requires 0.1µF bypass capacitor to GND |
| 2 - GND | Reference Ground | System ground return for all internal comparators and output drivers |
| 3 - MR | Manual Reset Input | Active-low signal with 26kΩ internal pullup to VCC; asserts RESET when pulled below 0.23×VCC |
| 4 - RESET | Reset Output | Active-high push-pull output; drives high when VCC is within 2.25V–2.75V window; sinks 1mA at VCC ≥ 1.71V |
| 5 - SET | Window Select Input | Grounded to configure ±5% window; open or floating not allowed; biasing to VCC/2 enables ±15% |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar window voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6755UKTD0+T | 3.3V nominal monitoring (T-suffix) instead of 2.5V (Z-suffix); same ±5% window, D0 timing, SOT23-5 package | Designed for 3.3V I/O rails, not 2.5V core supplies; UVTH/OVTH thresholds shifted accordingly | Select only if supervising 3.3V systems; not interchangeable with MAX6755UKZD0+T due to different factory-trimmed thresholds |
| TLV809E25DBVR | Single-channel 2.5V supervisor with 200ms reset timeout, open-drain output, and no SET pin configurability | Lacks window detection (only undervoltage), longer timeout, and no overvoltage response - unsuitable for dual-fault protection | Use only for basic brownout-only supervision; cannot replace MAX6755UKZD0+T in applications requiring simultaneous UV/OV detection |
Compared with MAX6755UKTD0+T and TLV809E25DBVR, the MAX6755UKZD0+T uniquely delivers factory-calibrated 2.5V window supervision with active-high push-pull output and 20µs response-enabling compact, high-reliability power integrity in space- and timing-critical 2.5V domains.

FAQ
What is the exact undervoltage and overvoltage threshold range for MAX6755UKZD0+T at -40°C to +125°C?
The MAX6755UKZD0+T has a factory-trimmed 2.5V nominal supply with ±5% window (SET = GND). Its undervoltage threshold (UVTH) ranges from 2.250V to 2.375V, and overvoltage threshold (OVTH) ranges from 2.625V to 2.750V across the full -40°C to +125°C operating temperature range, as specified in the Electrical Characteristics table for Z-suffix devices.
Can MAX6755UKZD0+T monitor voltages other than 2.5V?
No - the MAX6755UKZD0+T is factory-trimmed exclusively for 2.5V nominal monitoring (Z-suffix). It does not support adjustable thresholds or external resistor dividers. For other voltages, select corresponding suffix variants (e.g., T = 3.3V, W = 1.8V) or the adjustable MAX6763/MAX6764 series.
What is the function of the SET pin on MAX6755UKZD0+T, and how must it be connected?
The SET pin on MAX6755UKZD0+T configures the window width: grounding it selects ±5%, connecting to VCC selects ±10%, and biasing to VCC/2 selects ±15%. For Z-suffix operation, SET must be hard-connected to GND; floating or incorrect bias invalidates the specified thresholds and may cause erratic output behavior.
Does MAX6755UKZD0+T provide separate UV and OV outputs?
No - the MAX6755UKZD0+T provides a single combined RESET output that asserts (goes high) when VCC falls below UVTH *or* rises above OVTH. It belongs to the MAX6754–MAX6756 subgroup, which integrates UV/OV detection into one active-high push-pull signal, unlike MAX6757–MAX6764 with independent UV and OV pins.
Is MAX6755UKZD0+T qualified for automotive applications?
The MAX6755UKZD0+T is specified for -40°C to +125°C operation and meets extended temperature requirements common in automotive subsystems, but it is not AEC-Q100 qualified. Only /V-suffix variants in this family (e.g., MAX6755UKZD0/V+) carry AEC-Q100 qualification; standard +T parts are intended for industrial and telecom use.
