Product details
Overview
The MAX6710MUT+ from Maxim Integrated is a quad-voltage microprocessor supervisory IC that monitors four independent supply rails-IN1 (adjustable), IN2 = 3.0V, IN3 = 2.5V, and IN4 (adjustable)-and asserts a single active-low RESET output if any falls below its threshold. It features factory-trimmed -10% tolerance on the 3.0V and 2.5V channels, 0.62V internal reference for adjustable inputs, 140ms minimum reset timeout, and operates from -40°C to +85°C in telecom power management systems.
For engineers reviewing the MAX6710MUT+ datasheet, MAX6710MUT+ pinout, MAX6710MUT+ application, or MAX6710MUT+ equivalent, this page delivers verified electrical parameters, confirmed SOT23-6 pin mapping, exact monitored voltage configuration (3.0V/2.5V/adjustable/adjustable), reset timing behavior, and validated alternative parts for multi-rail system supervision.
Technical Context
The MAX6710MUT+ implements four independent precision comparators with a shared 0.62V bandgap reference and internal resistor-divider networks for fixed thresholds (3.0V, 2.5V) and direct comparator input access for adjustable channels. Each comparator includes 0.3% threshold hysteresis to reject noise without degrading accuracy.
It uses an open-drain RESET output with a 10µA internal pullup to IN2, remains valid down to IN1 or IN2 ≥ 1V, and guarantees correct reset assertion/deassertion across the full -40°C to +85°C range. The device draws only 35µA quiescent current and is immune to transients < 100µs at typical overdrive levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | IN1: adjustable (0.62V ref); IN2: 3.0V (-10%); IN3: 2.5V (-10%); IN4: adjustable - enables precise multi-supply validation in compact systems |
| Reset Timeout | 140ms (min) after all supplies recover - ensures reliable µP reset hold time for complex boot sequences |
| Supply Current | 35µA typical - minimizes impact on low-power standby modes in battery-backed or energy-sensitive designs |
| Threshold Accuracy | ±1.5% for adjustable inputs; ±1.2% for fixed 3.0V/2.5V thresholds - supports tight margining in modern low-voltage ASIC/FPGA rails |
| Operating Temp | -40°C to +85°C - qualified for industrial and telecom infrastructure environments without derating |
| Input Hysteresis | 0.3% of VTH - suppresses false resets from ripple or noise without requiring external RC filtering |
| RESET Output | Open-drain with 10µA internal pullup to IN2 - eliminates need for external pullup in same-rail logic interfacing |
Pinout & Package
Package: 6-pin SOT23-6, surface-mount, RoHS-compliant (lead-free), footprint per drawing 21-0058.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Adjustable voltage monitor input | Accepts external resistor divider; internal 0.62V comparator threshold enables monitoring of any rail ≥ 0.62V |
| 2 (IN2) | Fixed 3.0V monitor input & device power supply | Simultaneously powers the IC and monitors 3.0V rail at -10% threshold (2.70V); RESET valid down to IN2 = 1V |
| 3 (IN3) | Fixed 2.5V monitor input | Factory-trimmed to assert reset when 2.5V rail drops below 2.25V (-10%); no external components required |
| 4 (IN4) | Adjustable voltage monitor input | Same architecture as IN1; supports independent second adjustable rail (e.g., 1.2V, 1.8V) via external divider |
| 5 (GND) | Analog/digital ground reference | Common return for all comparators and RESET driver; must be low-impedance for accurate threshold sensing |
| 6 (RESET) | Active-low open-drain reset output | Asserts low on any undervoltage; holds low for ≥140ms after recovery; internal 10µA pullup simplifies interface |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent voltage monitoring | Simultaneous supervision of four rails (3.0V, 2.5V, two adjustable) in one 6-pin package - reduces BOM count vs. discrete supervisors |
| Factory-trimmed fixed thresholds | Guaranteed -10% tolerance on 3.0V (2.70V) and 2.5V (2.25V) channels - eliminates calibration effort in production |
| Adjustable input architecture | 0.62V internal reference with ±0.2µA max input bias - supports accurate scaling to 0.62V–5.5V rails using standard 1% resistors |
| Glitch-immune design | Immunity to transients < 100µs at typical overdrive - prevents spurious resets during switching noise or load dumps |
| Low-power operation | 35µA ICC at 5.5V - enables always-on supervision in battery-critical applications without measurable drain |
Applications
| Telecom Power Sequencing | Industrial PLC I/O Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710NUT+ | Same SOT23-6 package and pinout; monitors IN2=3.0V (-5%), IN3=2.5V (-5%) - tighter tolerance than MAX6710MUT+ | Better suited for systems requiring higher threshold accuracy on 3.0V/2.5V rails, e.g., high-reliability test equipment | Select when ±5% tolerance on fixed rails is mandatory; otherwise MAX6710MUT+ offers cost-optimized -10% performance |
| TPS3808G33DBVR | Triple supervisor (not quad); fixed 3.3V/3.0V/2.5V thresholds; 200ms reset timeout; 1.4µA quiescent current | Lacks fourth adjustable input; optimized for ultra-low-power battery systems but cannot replace quad monitoring function | Choose only if system has exactly three rails and sub-µA standby current is critical; not a functional substitute for MAX6710MUT+ |
Compared with MAX6710NUT+, the MAX6710MUT+ trades ±5% threshold tolerance for lower cost and broader margin acceptance; compared with TPS3808G33DBVR, it provides essential fourth-channel flexibility at higher quiescent current but enables true quad-rail supervision unattainable with triple devices.

FAQ
What voltage rails does the MAX6710MUT+ monitor and what are their thresholds?
The MAX6710MUT+ monitors four rails: IN1 (adjustable via external resistor divider, referenced to 0.62V), IN2 = 3.0V at -10% threshold (2.70V), IN3 = 2.5V at -10% threshold (2.25V), and IN4 (adjustable, same 0.62V reference). All thresholds are factory-trimmed and specified over -40°C to +85°C. The MAX6710MUT+ datasheet confirms these values in the Selector Guide and Electrical Characteristics tables.
Does the MAX6710MUT+ require external pull-up resistors on the RESET pin?
No, the MAX6710MUT+ includes a 10µA internal pullup to IN2, eliminating the need for an external pullup when interfacing with logic operating at the same voltage as IN2. An external pullup may be added only if interfacing with a different logic supply (e.g., 5V logic while IN2 = 3.0V), and internal circuitry prevents reverse current flow. This behavior is explicitly documented in the Applications Information section of the MAX6710MUT+ datasheet.
What is the reset timeout duration for the MAX6710MUT+ and how is it guaranteed?
The MAX6710MUT+ provides a minimum reset timeout of 140ms after all monitored voltages rise above their thresholds. This value is production-tested and guaranteed over temperature (-40°C to +85°C), with typical values of 200ms and a maximum of 280ms. The timeout is implemented internally and does not require external capacitors or timing components - a key advantage confirmed in the MAX6710MUT+ Electrical Characteristics table.
Can unused inputs on the MAX6710MUT+ be left floating?
No, unused inputs on the MAX6710MUT+ must not be left floating. For unused adjustable inputs (IN1 or IN4), connect a 1MΩ series resistor to IN2 (the 3.0V supply pin). For unused fixed inputs, tie them to a voltage exceeding their threshold (e.g., connect unused IN3 to 3.0V). Floating inputs risk erratic reset behavior due to noise coupling - this requirement is stated in the Applications Information section of the MAX6710MUT+ datasheet.
Is the MAX6710MUT+ compatible with lead-free PCB assembly processes?
Yes, the MAX6710MUT+ is RoHS-compliant and rated for lead-free reflow soldering. Its package (SOT23-6, drawing 21-0058, variation U6+1*) supports peak reflow temperatures up to +260°C, and the device is qualified per JEDEC J-STD-020 moisture sensitivity level 1. The "+" suffix in MAX6710MUT+ explicitly denotes lead-free packaging, as defined in Maxim's part numbering conventions and confirmed on the official product page.
