Product details
Overview
MAX6710AUT+T from Analog Devices is a precision quad-voltage microprocessor supervisory IC that monitors 5.0V (−10%), 3.3V (−10%), 2.5V (−10%), and one adjustable input down to 0.62V, asserting a single active-low open-drain RESET output when any threshold is violated. It operates from −40°C to +105°C in a 6-pin SOT23 package and delivers 140ms minimum reset timeout for reliable power-on sequencing in multi-rail systems.
For engineers reviewing the MAX6710AUT+T datasheet, MAX6710AUT+T pinout, MAX6710AUT+T application, or MAX6710AUT+T equivalent, key selection criteria include factory-trimmed thresholds for 5V/3.3V/2.5V supplies, 0.62V adjustable reference accuracy (±1.5%), 35μA supply current, 140ms reset timeout, and guaranteed operation with IN1 or IN2 ≥1.0V - critical for telecom, server, and industrial embedded power integrity.
Technical Context
The MAX6710AUT+T integrates four independent voltage comparators with a shared 0.62V bandgap reference and internal resistor-divider networks for fixed thresholds. Each comparator features 0.3% hysteresis and immunity to transients ≤100µs at 50mV overdrive.
It uses IN2 as both power source and monitored supply (3.3V, −10%), while IN1, IN3, and IN4 are dedicated to 5.0V, 2.5V, and adjustable monitoring respectively. The open-drain RESET output includes a 10µA internal pullup to IN2 and remains valid as long as IN1 or IN2 ≥1.0V.
Key Specifications

|---|---|
| Monitored Voltages | 5.0V (−10%), 3.3V (−10%), 2.5V (−10%), and one adjustable input (0.62V ref) |
| Reset Timeout Period | 140ms minimum - ensures stable CPU boot after all rails stabilize |
| Supply Current | 35μA typical - enables always-on supervision without impacting system power budget |
| Input Threshold Accuracy | ±1.5% for adjustable inputs; ±0.2V max deviation for fixed 5.0V/3.3V/2.5V options |
| Operating Temperature | −40°C to +105°C - qualified for industrial and telecom base station environments |
| RESET Output Type | Open-drain with 10μA internal pullup to IN2 - eliminates need for external pullup in 3.3V logic interfaces |
| Transient Immunity | Immune to IN_ glitches ≤100µs duration at 50mV overdrive - prevents false resets in noisy power rails |
Pinout & Package
MAX6710AUT+T is housed in a RoHS-compliant 6-pin SOT23-6 package (outline 21-0058), measuring 2.9mm × 1.6mm × 1.1mm, with gull-wing leads optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 - IN2 | Power-supply & monitored input | Provides device power and monitors 3.3V at −10% (2.97V); RESET valid if ≥1.0V |
| 3 - IN3 | Fixed-threshold input | Monitors 2.5V supply at −10% threshold (2.25V); shares same comparator architecture as IN1 |
| 4 - IN4 | Adjustable-threshold input | Accepts external resistor divider; threshold = 0.62V × (R1+R2)/R2; ±0.2μA input bias |
| 5 - GND | Analog/digital ground | Common return for all comparators and RESET driver; requires low-impedance connection |
| 6 - RESET | Active-low open-drain output | Asserts low on any undervoltage event; 10μA internal pullup to IN2; sinks up to 2mA |
Key Features

Applications
| Telecom Power Systems | Server Motherboard Sequencing |
|---|---|
|
Use Scenario: Monitoring primary 5V, 3.3V, and 2.5V rails plus FPGA core voltage in LTE base station power modules. IC Role / Device Role / Timing Role: Quad-voltage supervisor ensuring synchronized reset assertion across analog, digital, and I/O domains during AC brownout. Use Value: Prevents partial initialization by holding RESET for 140ms until all rails settle within tolerance - avoids firmware lockup and memory corruption. |
Use Scenario: Supervising CPU VDD, memory VDDQ, chipset 3.3V, and auxiliary 1.2V rails on dual-socket server motherboards. IC Role / Device Role / Timing Role: Centralized reset generator coordinating power-good signals from multiple DC/DC converters before BIOS execution. Use Value: Replaces three discrete supervisors with one 6-pin SOT23 device - saves 12mm² board area and improves thermal margin. |
| Industrial PLC Controllers | Network Switch Line Cards |
|
Use Scenario: Validating 24V-to-5V/3.3V/2.5V conversion stages and isolated I/O supply in programmable logic controllers operating at 85°C ambient. IC Role / Device Role / Timing Role: High-temperature-stable voltage monitor asserting RESET if any rail drops below spec during EMI-heavy motor switching events. Use Value: 0.3% hysteresis and transient immunity prevent nuisance resets during 100µs bus noise spikes - increases system uptime. |
Use Scenario: Ensuring clean startup of ASICs, PHYs, and management microcontrollers on 10G Ethernet line cards with tight power sequencing requirements. IC Role / Device Role / Timing Role: Single-point reset arbiter synchronizing power-up of SerDes, MAC, and control logic across multiple voltage domains. Use Value: 35μA quiescent current enables continuous supervision without derating PoE power budgets - critical for Class 4/5 devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710BUT+T | Same package and pinout; monitors 5.0V/3.3V/2.5V at −5% tolerance (vs. −10% for MAX6710AUT+T) | Higher threshold margins suit systems with tighter supply regulation and lower ripple | Select when 5.0V rail must remain >4.75V (not 4.50V) to assert reset - e.g., legacy PCI Express designs |
| TPS3808G33DBVR | Triple-monitor only; 3.3V fixed threshold with 200ms timeout; no adjustable input; 1.8V min VCC | Lacks fourth channel and sub-1V monitoring capability - insufficient for quad-rail systems | Use only if design requires only three rails and accepts loss of adjustable monitoring - not a drop-in replacement |
Compared with MAX6710AUT+T, MAX6710BUT+T offers tighter threshold tolerance but identical timing and package, while TPS3808G33DBVR omits the fourth monitor and adjustable input - making it unsuitable for applications requiring 5V/3.3V/2.5V/adjustable supervision in one device.

FAQ
What is the exact reset timeout period of the MAX6710AUT+T?
The MAX6710AUT+T guarantees a minimum reset timeout period of 140ms after all monitored voltages rise above their thresholds. Typical timeout is 200ms, with a maximum of 280ms across temperature and voltage ranges. This delay ensures robust CPU and memory initialization before release of the active-low RESET signal - a key differentiator from the 5μs propagation delay of the MAX6700 series.
Can the MAX6710AUT+T monitor a 1.8V supply?
No - the MAX6710AUT+T is configured to monitor 5.0V (−10%), 3.3V (−10%), and 2.5V (−10%) fixed thresholds, plus one adjustable input. For 1.8V monitoring, select MAX6710CUT+T or MAX6710DUT+T, which explicitly include 1.8V (−10% or −5%) in their fixed-threshold set. The MAX6710AUT+T top mark "AAZA" confirms its 5V/3.3V/2.5V/adjustable configuration per the Selector Guide.
Does the MAX6710AUT+T require an external pullup resistor on the RESET pin?
No - the MAX6710AUT+T includes a 10μA internal pullup to IN2, sufficient for interfacing with standard 3.3V CMOS logic. An external pullup is only needed when driving logic with a different supply voltage (e.g., 5V or 1.8V), where the internal pullup may not meet VIH requirements. In such cases, an external resistor to the target logic rail overrides the internal pullup without reverse current flow.
What is the minimum valid voltage on IN2 for the MAX6710AUT+T to maintain RESET functionality?
The MAX6710AUT+T guarantees correct RESET state as long as IN2 remains ≥1.0V across the full temperature range (−40°C to +105°C). Below 1.0V, RESET behavior is undefined. This feature allows supervised operation even during brownout conditions where IN2 dips temporarily - unlike devices requiring full VCC for reset validity.
How does the MAX6710AUT+T handle unused input pins like IN4 when configured for three-rail monitoring?
When IN4 is unused in the MAX6710AUT+T, it must not be left floating or tied to GND. Instead, connect a 1MΩ series resistor from IN4 to IN2 (3.3V) to limit bias current to <0.7μA while keeping the input above its 0.62V threshold. This prevents erroneous reset assertion and complies with the Applications Information section's guidance for unused adjustable inputs.
