Product details
Overview
MAX6710DUT-T from Maxim Integrated is a quad-voltage microprocessor supervisory IC in SOT23-6 package that monitors 5.0V (−5%), 3.3V (−5%), and 1.8V (−5%) supply rails plus one adjustable threshold down to 0.62V, asserting a single active-low open-drain RESET output when any falls below its threshold. It delivers 140ms minimum reset timeout, 35μA supply current, and operates from −40°C to +85°C for embedded power integrity in space-constrained systems.
For engineers reviewing the MAX6710DUT-T datasheet, MAX6710DUT-T pinout, MAX6710DUT-T application, or MAX6710DUT-T equivalent, this device serves as a precision, low-power, multi-rail voltage supervisor with factory-trimmed thresholds, immunity to short transients, and guaranteed operation across industrial temperature range - critical for reliable boot sequencing in servers, networking gear, and industrial controllers.
Technical Context
The MAX6710DUT-T integrates four independent voltage comparators with a shared 0.62V internal reference and precision resistor-divider networks for fixed thresholds. Each comparator features 0.3% VTH hysteresis to suppress noise-induced false resets without degrading accuracy.
Its architecture uses IN2 as both power source and monitored rail (3.3V), while IN1, IN3, and IN4 are dedicated to 5.0V (−5%), 1.8V (−5%), 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 ≥ 1V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | 5.0V (−5%), 3.3V (−5%), 1.8V (−5%), and one adjustable input (0.62V ref) |
| Reset Timeout Period | 140ms min - ensures stable CPU reset hold time after all supplies stabilize |
| Supply Current | 35μA typical - enables always-on supervision in battery-backed or low-power systems |
| Input Threshold Accuracy | ±1.5% for adjustable inputs; ±1.3% max deviation for factory-set thresholds (e.g., 4.63V typ for 5V −5%) |
| Operating Temperature | −40°C to +85°C - fully specified for industrial-grade reliability without derating |
| RESET Output Type | Open-drain with 10μA internal pullup to IN2 - eliminates need for external pullup in many 3.3V logic interfaces |
| Transient Immunity | Immune to IN_ transients ≤ 100µs at 100mV overdrive - prevents false resets during supply glitches |
Pinout & Package
Package: 6-pin SOT23-6, surface-mount, RoHS-compliant (lead-free with "+T" suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN1 | Fixed-threshold input | Monitors 5.0V supply at −5% threshold (4.50V min); powered from IN2 |
| 2 IN2 | Power supply & monitored input | 3.3V (−5%) rail - powers device and triggers reset if < 3.15V; RESET valid if ≥ 1.0V |
| 3 IN3 | Fixed-threshold input | Monitors 1.8V supply at −5% threshold (1.62V min) |
| 4 IN4 | Adjustable-threshold input | Accepts external resistor divider; internal 0.62V comparator reference enables monitoring down to 0.62V |
| 5 GND | Ground reference | Analog and digital ground common node; requires low-impedance connection for noise immunity |
| 6 RESET | Active-low reset output | Open-drain output pulled weakly (10μA) to IN2; sinks up to 2mA; asserts low on any undervoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Quad-voltage supervision | Simultaneously monitors four rails - reduces BOM count vs. discrete supervisors or multiple ICs |
| Factory-trimmed thresholds | Eliminates external resistors for 5.0V/3.3V/1.8V rails - improves accuracy and board area efficiency |
| Adjustable input with 0.62V reference | Supports custom rail monitoring (e.g., 1.2V, 0.9V) using two standard resistors - no trimming required |
| 140ms reset timeout | Guarantees sufficient hold time for CPU initialization and PLL lock before release - no external RC timing needed |
| IN_ transient immunity | Rejects sub-100µs supply dips - avoids spurious resets in electrically noisy environments like motor drives or switching PSUs |
Applications
| Telecom Line Cards | Industrial PLC Controllers |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710AUT-T | Same package and pinout; monitors 5.0V (−10%), 3.3V (−10%), 2.5V (−10%), and adjustable rail | Targets systems requiring tighter tolerance on 2.5V rail instead of 1.8V; not suitable where 1.8V −5% threshold is mandatory | Select when 2.5V rail supervision at −10% is prioritized over 1.8V −5% - verify compatibility with existing 1.8V design margin |
| TPS3808G33DBVR | Triple-supply monitor (3.3V, adjustable, adjustable); no 5V or 1.8V factory options; 200ms timeout; 1.5μA quiescent current | Lacks native 5V/1.8V fixed thresholds; requires external resistors for all rails; optimized for ultra-low-power battery systems | Choose only if system uses exclusively adjustable rails and demands sub-2μA supply current - MAX6710DUT-T provides superior accuracy and integration for fixed-rail designs |
Compared with MAX6710AUT-T, MAX6710DUT-T offers tighter −5% tolerance on 1.8V and 5V rails but sacrifices 2.5V monitoring; versus TPS3808G33DBVR, it delivers higher integration for fixed-rail systems at the cost of higher quiescent current - making it optimal for industrial/compute applications where accuracy and rail coverage outweigh ultra-low-power needs.

FAQ
What is the exact reset timeout duration for MAX6710DUT-T?
The MAX6710DUT-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 over temperature. This fixed delay is internally generated and requires no external components - ensuring consistent CPU reset hold time across operating conditions.
Which supply rails does MAX6710DUT-T monitor and at what thresholds?
The MAX6710DUT-T monitors four rails: IN1 at 5.0V (−5%, i.e., 4.50V min), IN2 at 3.3V (−5%, i.e., 3.15V min), IN3 at 1.8V (−5%, i.e., 1.62V min), and IN4 as an adjustable input referenced to 0.62V. The top mark "AAZD" confirms this specific configuration per Maxim's Selector Guide.
Can MAX6710DUT-T operate if only one monitored supply is present above 1V?
Yes - the MAX6710DUT-T maintains valid RESET output state as long as either IN1 or IN2 remains ≥ 1.0V. This allows continued reset assertion or deassertion even during partial supply failure, supporting fail-safe behavior in systems where full rail redundancy is not implemented.
Does MAX6710DUT-T require an external pullup resistor on the RESET pin?
No - the MAX6710DUT-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), and must be sized to overdrive the internal current without exceeding 20mA sink capability.
How is the adjustable threshold on IN4 configured for a 2.5V rail?
To monitor 2.5V on IN4, use a resistor divider where R1 = R2 × ((2.5V / 0.62V) − 1). For R2 = 100kΩ, R1 ≈ 303kΩ. Input bias current is ≤ 0.2μA, so resistor values ≤ 100kΩ for R2 introduce <1% error. The internal 0.62V reference ensures stable threshold setting independent of supply variation.
