Product details
Overview
MAX6756UKZD0+ from Maxim Integrated is a low-power, single-voltage window detector IC that monitors 2.5V system supplies for undervoltage/overvoltage faults with ±5% factory-trimmed thresholds (UVTH = 2.25V–2.375V, OVTH = 2.625V–2.75V), 20μs typical reset timeout, active-low open-drain RESET output, and manual reset input - used in DC-DC converter modules and automotive power management systems.
For engineers reviewing the MAX6756UKZD0+ datasheet, MAX6756UKZD0+ pinout, MAX6756UKZD0+ application, or MAX6756UKZD0+ equivalent, key selection criteria include its SOT23-5 package, -40°C to +125°C operation, 10μA supply current, ±5% window tolerance, and compatibility with 2.5V rail monitoring in space-constrained industrial and automotive designs.
Technical Context
The MAX6756UKZD0+ implements a fixed-threshold window detection architecture with internal voltage dividers calibrated for nominal 2.5V VCC monitoring. Its SET pin is tied to GND to configure the ±5% window, and it uses a bandgap reference with <0.7% hysteresis to reject transients up to 300ns.
It features a 20μs propagation delay (D0 timeout option), operates down to VCC = 1.0V while maintaining valid outputs, and asserts RESET low when VCC falls below UVTH or rises above OVTH - with no timeout on OV assertion and full latch behavior disabled (no OVLATCH pin).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Nominal Voltage | 2.5V - factory-trimmed for precise monitoring of 2.5V system rails |
| Window Tolerance | ±5% - configured by SET = GND; enables tight fault detection without external resistors |
| UV Threshold Range | 2.25V to 2.375V (falling VCC) - ensures reliable brownout detection across temperature |
| OV Threshold Range | 2.625V to 2.75V (rising VCC) - prevents overvoltage damage to downstream 2.5V logic |
| Supply Current | 13µA typ at 3.6V - supports ultra-low-power always-on monitoring in battery-backed systems |
| Timeout Option | D0 = 20µs typ - fast response for real-time power sequencing and fault shutdown |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial environments |
Pinout & Package
SOT23-5 package (2.9mm × 1.6mm × 1.1mm), thermally enhanced with exposed pad not present in this variant; RoHS-compliant lead-free construction (+ suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power Input & Monitored Voltage | Supplies device and serves as the 2.5V rail under surveillance; requires RC filter (100Ω + 0.1µF) per datasheet Figure 9 |
| 2 - GND | Ground Reference | Common return for internal reference, outputs, and SET bias; must be low-impedance |
| 3 - MR | Active-Low Manual Reset | Drives RESET low externally; internally pulled up to VCC via 26kΩ resistor; 4µs min pulse width |
| 4 - RESET | Open-Drain Output | Asserts low during UV/OV fault; requires external pullup; sinks ≥100µA at VOL ≤0.3V |
| 5 - SET | Window Select Input | Tied to GND to fix ±5% window; no external bias needed - eliminates component count |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Trimmed 2.5V Window Detection | Eliminates external resistor networks and calibration effort for 2.5V rail monitoring |
| 20µs Fast Timeout Response (D0) | Enables immediate system shutdown or alert before transient-induced corruption occurs |
| 10µA Ultra-Low Quiescent Current | Extends battery life in always-on monitoring applications such as telematics and ECU wake-up circuits |
| Open-Drain RESET Output | Allows wired-OR connection with other supervisors and compatibility with mixed-voltage logic domains |
| -40°C to +125°C Operation | Meets automotive AEC-Q100 stress test requirements for engine control and ADAS subsystems |
Applications
| Telecom Power Management | Automotive Body Control Module |
|---|---|

IC Role / Device Role / Timing Role: Power-good monitor enabling clock gating and initialization sequence only after 2.5V rail stabilizes within ±5%. Use Value: 20µs D0 timeout synchronizes with PCIe reset timing budgets without adding delay overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar window voltage detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809E25DBZR | Single-channel 2.5V supervisor with 200ms reset timeout, push-pull output, no SET pin or window adjustment | Lacks ±5% window flexibility; suited for simple reset-only use cases, not dual-threshold fault reporting | Select when only basic power-on reset is required and longer timeout is acceptable |
| ADM6315-25ARTZ-RL7 | 2.5V supervisor with 200ms timeout, open-drain output, no manual reset or window select capability | No MR input or programmable window - limited to static reset generation without user-initiated fault testing | Choose for cost-sensitive, non-latched reset applications where manual intervention is unnecessary |
Compared with TLV809E25DBZR and ADM6315-25ARTZ-RL7, the MAX6756UKZD0+ uniquely delivers factory-trimmed ±5% window detection with 20µs response and manual reset - critical for high-reliability 2.5V rail supervision where fast, precise, and controllable fault signaling is mandatory.

FAQ
What is the exact undervoltage and overvoltage threshold range for MAX6756UKZD0+?
The MAX6756UKZD0+ has a factory-trimmed 2.5V nominal supply with ±5% window tolerance. Its undervoltage threshold (UVTH) ranges from 2.25V to 2.375V (falling VCC), and overvoltage threshold (OVTH) ranges from 2.625V to 2.75V (rising VCC), specified over -40°C to +125°C. These values are confirmed in the Electrical Characteristics table under "Z, 2.5V" row with SET = GND.
Does MAX6756UKZD0+ support manual reset functionality?
Yes, the MAX6756UKZD0+ includes an active-low manual reset (MR) input on Pin 3. Driving MR low asserts the open-drain RESET output regardless of VCC level. The output remains asserted for 300ns after MR rises, and MR is internally pulled up to VCC via a 26kΩ resistor - fully documented in the Pin Description and Electrical Characteristics sections.
What package type and footprint does MAX6756UKZD0+ use?
The MAX6756UKZD0+ is housed in a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm), with pinout matching standard SOT23-5 land patterns. It is lead(Pb)-free and RoHS-compliant, indicated by the "+" suffix. No exposed pad is present - confirmed in Package Information and Pin Configurations sections.
Can MAX6756UKZD0+ monitor voltages below 1.0V?
No, the MAX6756UKZD0+ requires VCC ≥ 1.0V to operate, and its outputs remain valid only down to VCC = 1.0V. The device is designed to monitor 2.5V supplies (nominal), with minimum functional VCC of 1.4V for accurate threshold detection - per Absolute Maximum Ratings and Note 2 in the datasheet.
Is MAX6756UKZD0+ qualified for automotive applications?
The MAX6756UKZD0+ is not explicitly AEC-Q100 qualified, as automotive-grade variants carry the "/V" suffix (e.g., MAX6756UKZD0/V). This part lacks the /V designation and is rated for -40°C to +125°C operation - suitable for industrial and commercial automotive-adjacent systems but not certified for front-line automotive safety-critical use.
