Product details
Overview
MAX6754UKTD3 from Maxim Integrated is a low-power, single-voltage window detector that monitors system supply voltage (VCC) for undervoltage and overvoltage conditions, asserting a combined RESET output when thresholds are violated. It features factory-trimmed 3.3V nominal detection (T-suffix), ±10% window (SET = VCC), 100ms minimum reset timeout (D3 suffix), and operates from 1.0V to 6.0V supply across –40°C to +125°C - used in microprocessor power supervision for telecom and industrial DC-DC converter modules.
For engineers reviewing the MAX6754UKTD3 datasheet, MAX6754UKTD3 pinout, MAX6754UKTD3 application, or MAX6754UKTD3 equivalent, key selection criteria include its fixed 3.3V monitoring point, push-pull active-low RESET output, manual reset input (MR), 10µA supply current, and SOT23-5 package compatibility with space-constrained embedded power rails.
Technical Context
The MAX6754UKTD3 implements a precision internal voltage reference with factory-set UVTH and OVTH thresholds centered at 3.3V (±10%), enabling reliable detection of supply excursions without external components. Its SET pin selects window width via VCC/GND biasing, and MR provides asynchronous reset assertion independent of supply monitoring.
It uses a 20µs typical propagation delay for fast fault response and guarantees correct output logic state down to VCC = 1.0V - critical for brownout recovery in low-voltage microcontrollers. The device asserts RESET low when VCC falls below UVTH (≈2.97V) or rises above OVTH (≈3.63V), with deassertion delayed by ≥100ms after return to valid range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VCC Threshold | 3.3V (T-suffix), with ±10% window selected via SET = VCC |
| UV/OV Thresholds | UVTH = 2.97V–3.05V, OVTH = 3.63V–3.71V at TA = –40°C to +125°C |
| Reset Timeout | ≥100ms minimum (D3 suffix), ensuring stable MCU boot after power recovery |
| Supply Current | 10µA to 30µA (typ 13µA at 3.6V), enabling always-on supervision in battery-backed systems |
| Operating Range | VCC = 1.0V to 6.0V; outputs valid down to VCC = 1.0V for brownout operation |
| Propagation Delay | 20µs typ (tD-RESET, tD-UV, tD-OV), supporting real-time fault detection |
| Manual Reset Pulse | Min 4µs width; internally pulled up to VCC via 26kΩ resistor |
Pinout & Package
MAX6754UKTD3 is housed in a 5-pin SOT23-5 package (lead-free, RoHS-compliant), with exposed pad not present. 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 across –40°C to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Power Input & Monitored Voltage | Powers the IC and serves as the primary monitored supply rail; threshold detection is referenced to this pin |
| 2 (GND) | Ground Reference | Common return path for internal reference, comparators, and output drivers |
| 3 (MR) | Active-Low Manual Reset Input | Drives RESET low asynchronously; internal 26kΩ pullup ensures default high state during power-up |
| 4 (RESET) | Active-Low Push-Pull Output | Asserts low on UV/OV fault or MR activation; drives full rail-to-rail without external pullup |
| 5 (SET) | Window Width Select Input | Biasing to VCC configures ±10% window; connects to GND for ±5%, or VCC/2 for ±15% |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Trimmed 3.3V Detection | Eliminates external resistor dividers and calibration for standard I/O rail supervision |
| 100ms Minimum Reset Timeout | Ensures microcontroller completes power-on reset sequence before releasing reset signal |
| 10µA Typical Supply Current | Enables continuous monitoring in energy-sensitive applications like remote sensors and backup systems |
| Valid Outputs Down to 1.0V VCC | Supports brownout detection and controlled shutdown in ultra-low-voltage domains |
| 20µs Fault Propagation Delay | Provides rapid response to transient supply faults before system-level damage occurs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809K33DBZR | Single-channel 3.3V supervisor with 200ms reset timeout, open-drain RESET, no SET pin or manual reset | Lacks adjustable window and MR input; suited only for basic reset generation without configurability | Select when fixed 200ms timeout and open-drain interface are acceptable, and no window adjustment or manual reset is needed |
| ADM6315-33ARTZ-RL | 3.3V supervisor with 200ms timeout, push-pull RESET, no SET pin, no MR, higher 25µA ICC | No window select or manual reset; simpler interface but less flexible for design-in reuse | Choose for cost-sensitive, non-configurable applications where 200ms timeout suffices and layout space allows SOT23-3 |
Compared with TLV809K33DBZR and ADM6315-33ARTZ-RL, MAX6754UKTD3 uniquely supports ±5%/±10%/±15% window selection via SET pin and includes a manual reset input - enabling field-serviceable reset and adaptive tolerance for varying board-level supply tolerances.

FAQ
What is the exact undervoltage and overvoltage threshold range for MAX6754UKTD3?
The MAX6754UKTD3 has a nominal 3.3V detection point (T-suffix) with ±10% window selected by connecting SET to VCC. At –40°C to +125°C, UVTH is 2.97V to 3.05V and OVTH is 3.63V to 3.71V. These values are factory-trimmed and guaranteed across temperature without external calibration.
Does MAX6754UKTD3 support manual reset, and how is it implemented?
Yes, MAX6754UKTD3 includes an active-low manual reset input (MR) on Pin 3. Driving MR low asserts the RESET output regardless of VCC level. MR is internally pulled up to VCC via a 26kΩ resistor, and requires a minimum 4µs pulse width. The asserted state persists for the specified propagation delay after MR returns high.
What package type and pin count does MAX6754UKTD3 use?
MAX6754UKTD3 uses a 5-pin SOT23-5 package (lead-free, RoHS-compliant). Pinout is: Pin 1 = VCC, Pin 2 = GND, Pin 3 = MR, Pin 4 = RESET (active-low push-pull), Pin 5 = SET. No exposed pad is present in this variant.
Can MAX6754UKTD3 monitor voltages other than 3.3V?
No - MAX6754UKTD3 is factory-trimmed for 3.3V nominal detection (T-suffix). Other fixed thresholds (e.g., 5.0V, 2.5V) require different part numbers (e.g., MAX6754UKLD3 for 5V). For adjustable thresholds down to 0.5V, consider MAX6763 or MAX6764 instead of MAX6754UKTD3.
What is the supply current consumption of MAX6754UKTD3 across operating voltage?
MAX6754UKTD3 draws 10µA to 30µA (typ 13µA at 3.6V) over VCC = 1.0V to 6.0V. Current remains stable across temperature and load, enabling ultra-low-power supervision in always-on circuits such as battery-backed real-time clocks or watchdog subsystems.
