Product details
Overview
MAX6710MUT-T from Maxim Integrated is a quad-voltage microprocessor supervisory IC in SOT23-6 package that monitors four supply rails-IN1 (adjustable), IN2 = 3.0V, IN3 = 2.5V, and IN4 (adjustable)-with factory-trimmed -10% thresholds and asserts an active-low open-drain RESET output when any falls below its threshold. It delivers 140ms minimum reset timeout, 35μA quiescent current, and operates from -40°C to +85°C. Used in servers and industrial embedded systems for reliable power-on reset sequencing.
For engineers reviewing the MAX6710MUT-T datasheet, MAX6710MUT-T pinout, MAX6710MUT-T application, or MAX6710MUT-T equivalent, key selection criteria include its fixed 3.0V/2.5V monitoring pair with -10% tolerance, adjustable low-voltage inputs down to 0.62V, 140ms reset timeout, SOT23-6 footprint compatibility, and immunity to short supply transients.
Technical Context
The MAX6710MUT-T integrates four precision voltage comparators with a shared 0.62V internal reference and resistor-divider networks for factory-set thresholds on IN2 and IN3, while IN1 and IN4 accept external resistor dividers for adjustable monitoring. Each comparator includes 0.3% VTH hysteresis to suppress noise-induced false resets.
Its RESET output remains asserted for ≥140ms after all monitored voltages recover above threshold, ensuring stable processor initialization. Power is derived from IN2 (3.0V), which also serves as the internal pullup source for the open-drain RESET output (10μA typical), eliminating need for external pullup in many 3.0V logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | IN1 (adjustable), IN2 = 3.0V (-10%), IN3 = 2.5V (-10%), IN4 (adjustable) - supports mixed-rail systems without external resistors for fixed rails |
| Reset Timeout | 140ms min - guarantees sufficient hold time for CPU boot sequence in servers and industrial controllers |
| Supply Current | 35μA typ - enables use in always-on subsystems with minimal battery drain or standby power impact |
| Input Threshold Accuracy | ±1.5% for adjustable inputs, ±1.3% for factory-set 3.0V/2.5V - ensures precise undervoltage detection across temperature |
| Operating Temp Range | -40°C to +85°C - qualified for industrial and telecom equipment operating in uncontrolled environments |
| RESET Output Type | Open-drain with 10μA internal pullup to IN2 - simplifies interface to 1.8V–5.5V logic without external components |
| Transient Immunity | Immune to IN_ transients < 100µs at ≤100mV overdrive - prevents spurious resets during power rail noise or load switching |
Pinout & Package
Package: 6-pin SOT23-6, surface-mount, RoHS-compliant, tape-and-reel delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable voltage input | Accepts external resistor divider; internal threshold = 0.62V; supports monitoring down to 0.62V with 1.5% accuracy |
| 2 - IN2 | Fixed 3.0V monitored supply & power source | Supplies device operation and provides internal pullup for RESET; valid down to 1.0V for RESET assertion |
| 3 - IN3 | Fixed 2.5V monitored supply | Factory-trimmed -10% threshold (2.25V); no external components required for 2.5V rail supervision |
| 4 - IN4 | Adjustable voltage input | Same electrical behavior as IN1; allows dual low-voltage rail monitoring (e.g., 1.2V core + 1.8V I/O) |
| 5 - GND | Analog/digital ground reference | Common return for all comparators and RESET driver; requires low-impedance connection to system ground plane |
| 6 - RESET | Active-low open-drain reset output | Asserts low if any INx drops below threshold; stays low ≥140ms after recovery; pulls up weakly to IN2 |
Key Features
| Feature | Design Value |
|---|---|
| Quad-supply monitoring with mixed fixed/adjustable inputs | Reduces BOM count by replacing four discrete supervisors; IN2/IN3 require zero external components |
| 140ms guaranteed reset timeout | Ensures full CPU initialization before release, eliminating need for external RC timing networks |
| 0.62V precision internal reference | Enables accurate low-voltage monitoring (e.g., 1.0V, 1.2V, 1.8V) using only two external resistors per input |
| 10μA internal RESET pullup to IN2 | Eliminates external pullup resistor in 3.0V systems; saves PCB area and reduces component cost |
| 0.3% threshold hysteresis | Rejects high-frequency noise on supply lines without degrading DC accuracy or requiring external filtering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710LUT-T | Same pinout and package; monitors IN2 = 3.0V and IN3 = 2.5V but with -5% (not -10%) threshold tolerance | Better suited for systems requiring tighter margin on 3.0V/2.5V rails; less headroom for supply droop | Select MAX6710LUT-T when design tolerances demand ±2.5% threshold accuracy instead of ±5% |
| TPS3808G33DBVR | Triple-supply monitor (not quad); fixed 3.3V/3.0V/2.5V thresholds; 200ms timeout; higher 65μA ICC | Lacks fourth adjustable input; requires external circuitry to add fourth rail supervision | Choose TPS3808G33DBVR only if exactly three rails need monitoring and SOT23-6 footprint is mandatory |
Compared with MAX6710MUT-T, MAX6710LUT-T offers tighter threshold tolerance but reduced droop margin, while TPS3808G33DBVR sacrifices quad monitoring capability and adds supply current overhead-making MAX6710MUT-T optimal for cost-sensitive, four-rail industrial designs needing -10% robustness.

FAQ
What is the exact voltage threshold configuration for MAX6710MUT-T?
The MAX6710MUT-T monitors IN2 at 3.0V with -10% tolerance (2.70V min), IN3 at 2.5V with -10% tolerance (2.25V min), and IN1/IN4 as adjustable inputs with internal 0.62V reference. This configuration is confirmed in the Selector Guide (top mark AAZM) and Electrical Characteristics table under "Threshold Voltage" for 3.0V (-10%) and 2.5V (-10%) entries.
Does MAX6710MUT-T require external pullup resistors for the RESET output?
No-MAX6710MUT-T includes a 10μA internal pullup to IN2, making external pullup unnecessary when interfacing with 3.0V logic. If driving higher-voltage logic (e.g., 5V), an external pullup may be added without risk of reverse current, as internal circuitry blocks backflow from the external node to IN2.
Can unused inputs on MAX6710MUT-T be left floating?
No-unused inputs must not float. For unused adjustable inputs (IN1 or IN4), connect a 1MΩ series resistor to IN2. For unused fixed inputs, tie to a supply > threshold voltage. Floating inputs risk false resets due to leakage or noise coupling, as specified in the Applications Information section.
What is the minimum valid voltage on IN2 to maintain RESET functionality in MAX6710MUT-T?
RESET remains valid (i.e., correctly asserted/deasserted) as long as IN2 ≥ 1.0V, per Absolute Maximum Ratings and Electrical Characteristics notes. Below 1.0V, RESET state is undefined-even if other inputs are within range-because IN2 powers internal circuitry and supplies the RESET pullup.
How does MAX6710MUT-T handle short-duration supply transients?
MAX6710MUT-T rejects transients < 100µs duration when overdrive is ≤100mV, as shown in Figure MAX6700 toc04. This immunity stems from internal filtering and comparator hysteresis, preventing false resets during switching noise or load dumps common in industrial power systems.
