Product details
Overview
The MAX6755UKZD0 from Maxim Integrated is a single-supply, low-power window voltage detector with factory-trimmed 2.5V nominal threshold, ±10% window (2.25V UV / 2.75V OV), active-high push-pull RESET output, and manual reset input - designed for reliable power supply monitoring in microprocessor-based systems requiring precise undervoltage/overvoltage fault detection.
For engineers reviewing the MAX6755UKZD0 datasheet, MAX6755UKZD0 pinout, MAX6755UKZD0 application, or MAX6755UKZD0 equivalent, this device delivers deterministic 20µs propagation delay, 10µA quiescent current, operation down to 1.0V VCC, and robust transient immunity - critical for automotive, industrial, and telecom power-rail supervision where supply stability directly impacts system boot integrity and runtime safety.
Technical Context
The MAX6755UKZD0 implements a precision bandgap-referenced comparator architecture with internal voltage dividers set for 2.5V nominal monitoring. Its SET pin is connected to VCC to configure the ±10% window, and its active-high RESET output asserts only when VCC falls below UVTH (2.25V) or rises above OVTH (2.75V), with no timeout delay on OV assertion and immediate deassertion after recovery.
It integrates a 26kΩ internal pull-up on MR, supports manual reset assertion with ≥4µs pulse width, and maintains valid output states across -40°C to +125°C while consuming ≤30µA at 3.6V. The device operates without external components beyond standard 0.1µF VCC bypassing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VCC Threshold | 2.5V - factory-trimmed for direct monitoring of common 2.5V system rails without external resistors |
| Window Tolerance | ±10% - configured by SET = VCC, yielding UVTH = 2.25V and OVTH = 2.75V at +25°C |
| RESET Output Type | Active-high push-pull - drives high to VCC when asserted, eliminating need for external pull-up |
| Supply Current | 13µA (typ) at 3.6V - enables always-on supervision in battery-backed or ultra-low-power systems |
| Operating Voltage Range | 1.0V to 6.0V - RESET remains valid even as VCC drops to 1.0V, supporting brown-out detection during deep discharge |
| Propagation Delay | 20µs (typ) - ensures rapid fault response for real-time system protection and deterministic reset timing |
| Temperature Range | -40°C to +125°C - qualified for under-hood automotive, industrial control, and harsh-environment applications |
Pinout & Package
MAX6755UKZD0 is housed in a 5-pin SOT23-5 package with exposed pad (lead-free, RoHS-compliant). Pin 1 is VCC, Pin 2 is GND, Pin 3 is MR, Pin 4 is RESET, and Pin 5 is SET. The package footprint is 2.9mm × 1.6mm × 1.1mm, compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Supply | Primary power rail input and the voltage being supervised; powers internal circuitry and defines reference scaling |
| 2 - GND | Ground Reference | Common return path for all internal comparators, reference, and output drivers; must be low-impedance |
| 3 - MR | Active-Low Manual Reset Input | Drives RESET high when pulled low ≥4µs; internally pulled up to VCC via 26kΩ resistor for fail-safe default |
| 4 - RESET | Active-High Push-Pull Output | Asserts high during UV/OV fault; deasserts immediately upon VCC recovery - no timeout delay required |
| 5 - SET | Window Threshold Select | Biasing to VCC configures ±10% window; connects to internal divider to scale UVTH/OVTH relative to VCC |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Trimmed 2.5V Window Detection | Eliminates external resistor networks and calibration, reducing BOM count and layout area for 2.5V rail monitoring |
| Active-High Push-Pull RESET | Removes dependency on external pull-up resistors, simplifying interface with µP reset inputs requiring high-active logic |
| 20µs Propagation Delay | Enables sub-100µs fault-to-action response, meeting tight timing budgets in real-time embedded controllers |
| 10µA Quiescent Current | Supports continuous supervision in energy-constrained applications such as battery-powered telemetry and sensor nodes |
| Immunity to Short Voltage Transients | Rejects <300ns glitches, preventing false resets caused by switching noise or ESD-induced supply perturbations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage window detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809E25DBZR | Single 2.5V supervisor with fixed 200ms reset timeout; open-drain active-low RESET; no SET pin or window adjustment | Lacks undervoltage/overvoltage window capability - only detects undervoltage; requires external pull-up and cannot flag overvoltage faults | Select when only brown-out protection is needed and active-low reset with timeout suffices; not suitable for bidirectional rail monitoring |
| ADM6315-25ARTZ-R7 | 2.5V supervisor with 200ms timeout, active-low open-drain RESET, ±2.5% accuracy, but no overvoltage detection or SET configurability | Provides tighter UV threshold tolerance but no OV monitoring - fails to detect dangerous overvoltage transients on 2.5V rail | Choose for high-accuracy undervoltage-only supervision where cost is prioritized over dual-fault coverage |
Compared with TLV809E25DBZR and ADM6315-25ARTZ-R7, the MAX6755UKZD0 uniquely combines ±10% window detection, active-high push-pull output, and manual reset in a 5-pin SOT23 - enabling complete 2.5V rail health verification without additional components or logic inversion.

FAQ
What is the exact undervoltage and overvoltage threshold for MAX6755UKZD0?
The MAX6755UKZD0 has a factory-trimmed nominal VCC threshold of 2.5V. With SET tied to VCC, it configures a ±10% window: undervoltage threshold (UVTH) is 2.25V (min 2.16V, max 2.34V) and overvoltage threshold (OVTH) is 2.75V (min 2.66V, max 2.84V) over -40°C to +125°C. These values are guaranteed by design and verified across temperature.
Does MAX6755UKZD0 require external resistors to set its detection thresholds?
No, the MAX6755UKZD0 does not require external resistors. Its 2.5V nominal thresholds are factory-trimmed and internally scaled. The SET pin selects window width (±5%/±10%/±15%) via connection to GND/VCC/VCC/2 - no external divider network is needed for standard 2.5V rail monitoring.
What is the function of the RESET output on MAX6755UKZD0?
The RESET output on MAX6755UKZD0 is an active-high push-pull driver. It asserts high when VCC falls below UVTH (2.25V) or rises above OVTH (2.75V), and deasserts low immediately upon VCC returning within the valid window. No external pull-up is required, and no timeout delay is applied to the RESET assertion/deassertion.
Can MAX6755UKZD0 operate with supply voltages below 2.5V?
Yes, the MAX6755UKZD0 operates with VCC from 1.0V to 6.0V. While its detection window is centered on 2.5V, the internal circuitry remains functional and outputs retain correct logic states down to VCC = 1.0V - enabling brown-out detection during deep discharge scenarios in battery-powered systems.
How does the manual reset (MR) pin behave on MAX6755UKZD0?
The MR pin on MAX6755UKZD0 is active-low with internal 26kΩ pull-up to VCC. Driving MR low for ≥4µs forces RESET high regardless of VCC level. After MR returns high, RESET deasserts after a 20µs propagation delay. This allows hardware-initiated system reset independent of supply voltage status.
