Product details
Overview
MAX6754UKLD0 from Maxim Integrated is a low-power, single-voltage window detector IC that monitors system supply voltage (VCC) for undervoltage and overvoltage conditions, asserting a combined RESET output when thresholds are violated. It features factory-trimmed 5V nominal detection, ±5% window tolerance (SET = GND), 20µs typical propagation delay, and operates from VCC = 1.0V to 6.0V with 10µA supply current. It is used in microprocessor power supervision for telecom and industrial embedded systems.
For engineers reviewing the MAX6754UKLD0 datasheet, MAX6754UKLD0 pinout, MAX6754UKLD0 application, or MAX6754UKLD0 equivalent, key selection considerations include its fixed 5V threshold with ±5% window, push-pull active-low RESET output, manual reset input (MR), SOT23-5 package, and guaranteed operation down to VCC = 1.0V with outputs valid at low supply.
Technical Context
The MAX6754UKLD0 implements a precision internal reference-based window comparator architecture with separate UVTH and OVTH thresholds derived from a factory-trimmed resistor divider. Its SET pin selects ±5%, ±10%, or ±15% window width by biasing to GND, VCC, or VCC/2 respectively.
It provides a single combined RESET output (active-low push-pull) that asserts on either VCC < UVTH or VCC > OVTH, with no timeout delay for OV events and a 20µs propagation delay (D0 option). The MR input enables external reset assertion with 26kΩ internal pullup and 4µs minimum pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0V to 6.0V - Enables operation across brown-out and low-VCC conditions; outputs remain valid down to 1.0V. |
| VCC Threshold (Nominal) | 5.0V - Factory-trimmed for monitoring standard 5V system rails without external components. |
| Window Tolerance | ±5% - Set by connecting SET pin to GND; defines UVTH = 4.5V–4.75V and OVTH = 5.25V–5.5V at +25°C. |
| Supply Current (ICC) | 10µA to 30µA - Ultra-low quiescent current enables use in battery-backed or always-on supervision circuits. |
| Reset Propagation Delay | 20µs (typ) - Fast response ensures timely microprocessor reset during transient supply faults. |
| Operating Temperature | -40°C to +125°C - Qualified for automotive, industrial, and harsh-environment applications. |
| Output Type | Active-low push-pull RESET - Provides rail-to-rail drive without external pullup; sinks ≥1.0mA at VCC ≥ 1.71V. |
Pinout & Package
MAX6754UKLD0 is housed in a 5-pin SOT23-5 package with exposed pad (not connected per datasheet). Pin 1 is VCC, Pin 2 is GND, Pin 3 is MR, Pin 4 is RESET, and Pin 5 is SET. All pins support operation over -40°C to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Supply | Primary power source and the voltage being supervised; must be ≥1.4V for accurate monitoring. |
| 2 - GND | Ground Reference | System ground return for all internal references and output drivers; connects to exposed pad in TDFN variants (not applicable here). |
| 3 - MR | Active-Low Manual Reset Input | Drives RESET low externally; internally pulled up to VCC via 26kΩ; requires ≥4µs pulse width for reliable assertion. |
| 4 - RESET | Combined UV/OV Output | Active-low push-pull output asserted when VCC < UVTH or VCC > OVTH; deasserts after 20µs once condition clears. |
| 5 - SET | Window Width Select Input | Biasing to GND configures ±5% window; critical for setting detection hysteresis without external resistors. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Trimmed 5V Detection | Eliminates need for external resistor dividers or calibration; supports immediate deployment on 5V rails. |
| ±5% Window Selectable via SET Pin | Reduces BOM count and layout area by enabling window adjustment with single pin connection instead of discrete resistors. |
| 20µs Propagation Delay (D0 Option) | Enables rapid fault response in high-speed digital systems where delayed reset could cause state corruption. |
| 10µA Typical Supply Current | Extends battery life in portable or energy-harvested systems requiring continuous power-rail monitoring. |
| Operation Down to VCC = 1.0V | Ensures deterministic RESET behavior during deep brown-out, preventing undefined microprocessor states. |
Applications
| Telecom Power Supervision | Industrial Microcontroller Reset |

Use Value: Push-pull RESET output drives heavy capacitive loads directly without pull-up resistor, reducing board space and improving noise immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage window detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6755UKLD0 | Active-high push-pull RESET output (vs. MAX6754UKLD0's active-low); identical thresholds, timing, and pinout. | Requires inverted reset logic in host system; not drop-in compatible with active-low reset architectures. | Select MAX6755UKLD0 only if system reset controller expects active-high assertion. |
| TLV809E50DBZR | Single undervoltage detector (no overvoltage function); 5.0V threshold, ±2% accuracy, SOT23-3 package; no SET or MR pins. | Lacks OV monitoring and manual reset capability; suitable only for UV-only supervision with tighter tolerance. | Choose TLV809E50DBZR when overvoltage detection is unnecessary and higher threshold accuracy is prioritized over feature set. |
Compared with MAX6755UKLD0, MAX6754UKLD0 provides native active-low reset signaling without level-shifting; compared with TLV809E50DBZR, it adds overvoltage protection and manual reset-critical for full window supervision in mission-critical power domains.

FAQ
What is the exact undervoltage and overvoltage threshold range for MAX6754UKLD0?
The MAX6754UKLD0 has a nominal 5.0V threshold with ±5% window tolerance (SET = GND), resulting in an undervoltage threshold (UVTH) of 4.500V–4.750V and overvoltage threshold (OVTH) of 5.250V–5.500V over -40°C to +125°C. These values are factory-trimmed and specified in the Electrical Characteristics table under "L, 5V" suffix conditions.
Does MAX6754UKLD0 support dual-voltage monitoring?
No, MAX6754UKLD0 is a single-voltage window detector monitoring only VCC. Dual-voltage capability (VCC and VCC2) is exclusive to MAX6760–MAX6762 variants. The MAX6754UKLD0 pinout lacks VCC2 and OVLATCH pins, and its functional diagram confirms single-supply operation.
What output configuration does MAX6754UKLD0 use for its RESET signal?
MAX6754UKLD0 provides an active-low push-pull RESET output (Pin 4). It drives low with ≤0.3V at ISINK ≥ 1.0mA (VCC ≥ 1.71V) and drives high to ≥0.8 × VCC at ISOURCE ≥ 0.8mA, eliminating the need for an external pull-up resistor.
Can MAX6754UKLD0 operate reliably below 1.4V VCC?
Yes - while accurate voltage monitoring requires VCC ≥ 1.4V, MAX6754UKLD0 guarantees correct RESET logic state (asserted/deasserted) for VCC down to 1.0V. This ensures fail-safe behavior during deep brown-out conditions before the device loses functionality.
Is the SET pin on MAX6754UKLD0 required to be actively driven, or can it be left floating?
The SET pin on MAX6754UKLD0 must not be left floating. To configure the ±5% window, it must be hard-connected to GND. Floating SET may result in undefined window width due to input bias uncertainty; the datasheet specifies defined logic levels (0V, VCC, or VCC/2) for reliable operation.
