Product details
Overview
The MAX6754UKLD3+T from Analog Devices is a low-power, single-supply window voltage detector with factory-trimmed 3.3V nominal monitoring, ±10% window (3.0V–3.63V), 100ms minimum reset timeout, active-low push-pull RESET output, and manual reset input. It monitors system power rails in telecom and server applications to prevent microprocessor malfunction during undervoltage/overvoltage events.
For engineers reviewing the MAX6754UKLD3+T datasheet, MAX6754UKLD3+T pinout, MAX6754UKLD3+T application, or MAX6754UKLD3+T equivalent, key selection criteria include its fixed 3.3V threshold with ±10% window, 100ms timeout delay, 10µA supply current, -40°C to +125°C operation, and SOT23-5 package compatibility with space-constrained embedded power management designs.
Technical Context
This device implements a precision internal bandgap reference and comparator-based window detection architecture. It compares VCC against factory-set UVTH (3.0V) and OVTH (3.63V) thresholds with 0.7% hysteresis, asserting RESET when VCC falls below UVTH or rises above OVTH.
The RESET output is push-pull with guaranteed logic state down to VCC = 1.0V, and includes a 100ms minimum timeout period after VCC returns to valid range. A manual reset input (MR) provides external assertion control with 4µs minimum pulse width and 300ns propagation delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 3.3V - Factory-trimmed for direct monitoring of 3.3V system rails without external resistors. |
| Window Tolerance | ±10% - Sets undervoltage threshold at 3.0V and overvoltage threshold at 3.63V at +25°C. |
| Reset Timeout | 100ms min - Ensures stable processor reset hold time after supply recovery; no 20µs option. |
| Supply Current | 13µA typ @ 3.6V - Enables ultra-low-power operation in battery-backed or always-on systems. |
| Operating Temp | -40°C to +125°C - Qualified for automotive under-hood and industrial high-temp environments. |
| Output Type | Active-low push-pull RESET - Drives directly into µP reset pin; no external pull-up required. |
| Manual Reset | MR input with 26kΩ internal pull-up - Allows system-initiated reset independent of supply condition. |
Pinout & Package
MAX6754UKLD3+T is housed in a 5-pin SOT23-5 package (package code U5+1A, outline 21-0057), with exposed pad not present. Pin 1 is VCC, Pin 2 is GND, Pin 3 is MR, Pin 4 is RESET, Pin 5 is SET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Supply | Supplies device and serves as the voltage being monitored; valid from 1.0V to 6.0V. |
| 2 - GND | Ground Reference | Common return path for all internal circuitry and output drivers. |
| 3 - MR | Active-Low Manual Reset | Asserts RESET when pulled low; internally pulled up to VCC via 26kΩ resistor. |
| 4 - RESET | Active-Low Push-Pull Output | Drives low during UV/OV fault or MR assertion; deasserts after 100ms timeout post-recovery. |
| 5 - SET | Window Threshold Select | Connected to VCC for ±10% window (as configured in MAX6754UKLD3+T). |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar window voltage detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6754UKTD3+T | Same 3.3V nominal, ±10% window, 100ms timeout, but in SOT23-6 package with separate UV and OV outputs. | Requires dual-output signaling (e.g., separate fault flags for UV and OV) rather than combined RESET assertion. | Select when independent undervoltage and overvoltage reporting is needed; not pin-compatible with MAX6754UKLD3+T. |
| TLV809E33DBZR | Single 3.3V supervisor with 200ms reset timeout, open-drain output, and no manual reset input. | Lacks MR functionality and push-pull drive; requires external pull-up and cannot initiate reset externally. | Choose for cost-sensitive, non-MR applications where longer timeout and open-drain flexibility are acceptable. |
Compared with MAX6754UKTD3+T and TLV809E33DBZR, the MAX6754UKLD3+T uniquely delivers combined UV/OV reset assertion in a compact SOT23-5 with integrated manual reset-enabling simpler, smaller, and more responsive power supervision in space-constrained 3.3V systems.

FAQ
What is the exact undervoltage and overvoltage threshold for MAX6754UKLD3+T?
The MAX6754UKLD3+T has a factory-trimmed nominal voltage of 3.3V with ±10% window tolerance. Its undervoltage threshold (UVTH) is 3.0V and overvoltage threshold (OVTH) is 3.63V at +25°C, with 0.7% hysteresis. These values are specified over -40°C to +125°C and remain stable across temperature and supply variation per the datasheet's electrical characteristics table.
Does MAX6754UKLD3+T support operation below 3.3V supply?
Yes, MAX6754UKLD3+T operates with VCC from 1.0V to 6.0V. While it is optimized to monitor a 3.3V rail, its internal circuitry remains functional and RESET output retains correct logic state down to VCC = 1.0V - enabling use in brownout detection scenarios where supply dips below nominal.
Is the RESET output of MAX6754UKLD3+T push-pull or open-drain?
The MAX6754UKLD3+T features an active-low push-pull RESET output (Pin 4). It actively drives low during fault conditions and actively drives high when deasserted - eliminating the need for an external pull-up resistor and improving noise immunity compared to open-drain alternatives.
What does the 'D3' suffix in MAX6754UKLD3+T indicate?
The 'D3' suffix in MAX6754UKLD3+T specifies the 100ms minimum reset timeout period. This distinguishes it from the 'D0' variant (20µs propagation delay only). The D3 option ensures sustained reset assertion long enough for full system stabilization after supply recovery.
Can MAX6754UKLD3+T be used in automotive applications?
While MAX6754UKLD3+T itself is not AEC-Q100 qualified, the /V suffix variants (e.g., MAX6754UKLD3/V+) in the same family are automotive-qualified. For automotive ADAS or body control modules requiring qualification, select the /V version; MAX6754UKLD3+T is suitable for industrial and telecom applications operating across -40°C to +125°C.
