Product details
Overview
MAX6710FUT+T from Analog Devices is a quad-voltage microprocessor supervisory IC that monitors four independent supply rails-IN1 (adjustable), IN2 (3.3V), IN3 (2.5V), and IN4 (1.8V, −5% tolerance)-and asserts a single active-low open-drain RESET output if any falls below its threshold. It delivers 0.62V adjustable threshold accuracy (±1.5%), 140ms minimum reset timeout, and operates across −40°C to +105°C in telecom and industrial computing systems.
For engineers reviewing the MAX6710FUT+T datasheet, MAX6710FUT+T pinout, MAX6710FUT+T application, or MAX6710FUT+T equivalent, this device supports precision multi-rail monitoring with factory-trimmed thresholds, low 35μA quiescent current, and robust transient immunity-key for high-reliability embedded power sequencing and system reset integrity validation.
Technical Context
The MAX6710FUT+T implements four independent voltage comparators referenced to a stable 0.62V internal bandgap, each with 0.3% threshold hysteresis for noise immunity. IN2 serves as both monitored input and primary power source (1.2V–5.5V), while IN1, IN3, and IN4 are configured per Selector Guide: IN1 = adjustable (0.62V base), IN3 = 2.5V (−5%), IN4 = 1.8V (−5%).
Reset assertion is combinatorial: any input falling below its threshold pulls RESET low; deassertion requires all inputs to exceed thresholds *and* wait out the guaranteed 140ms min timeout. The open-drain RESET includes a 10μA internal pullup to IN2, eliminating need for external pullup in many 3.3V logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | IN1: adjustable (0.62V base); IN2: 3.3V; IN3: 2.5V (−5%); IN4: 1.8V (−5%) - enables precise multi-rail validation without external resistors for fixed rails |
| Reset Timeout Period | 140ms (min) - ensures sufficient hold time for CPU initialization and peripheral stabilization before release |
| Supply Current | 35μA (typ) - minimizes standby power impact in battery-backed or energy-sensitive systems |
| Threshold Accuracy | ±1.5% for adjustable inputs; ±0.13V max deviation for fixed 1.8V/2.5V/3.3V options - guarantees deterministic reset timing across temperature |
| Operating Temperature | −40°C to +105°C - validated for extended-range deployment in industrial controllers and telecom line cards |
| Input Transient Immunity | Immune to ≤100µs transients down to 100mV overdrive - prevents false resets during supply coupling or switching noise |
| RESET Output Type | Open-drain with 10μA internal pullup to IN2 - simplifies interface to 1.8V–5.5V logic families without external components |
Pinout & Package
MAX6710FUT+T is housed in a 6-pin SOT23-6 package (outline 21-0058), footprint code U6+1, RoHS-compliant, tape-and-reel only (2500-piece minimum).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable voltage monitor input | Accepts external resistor divider to set threshold ≥0.62V; input bias ≤0.4μA ensures <1% error with R2 ≤100kΩ |
| 2 - IN2 | Primary power supply & monitored input | Supplies device core; monitors 3.3V rail; RESET remains valid as long as IN2 ≥1.0V |
| 3 - IN3 | Fixed-threshold monitor input | Factory-set to 2.5V (−5% tolerance); no external components required |
| 4 - IN4 | Fixed-threshold monitor input | Factory-set to 1.8V (−5% tolerance); immune to short transients per spec |
| 5 - GND | Analog and digital ground reference | Single ground pin shared by all comparators and RESET driver; requires low-impedance PCB connection |
| 6 - RESET | Active-low open-drain reset output | Pulled low on fault; releases after 140ms timeout; internal 10μA pullup to IN2 eliminates need for external resistor in 3.3V systems |
Key Features
| Feature | Design Value |
|---|---|
| Quad-supply monitoring with mixed fixed/adjustable thresholds | Supports heterogeneous power architectures (e.g., 3.3V I/O, 2.5V core, 1.8V memory, adjustable auxiliary rail) in one 6-pin IC |
| 140ms min reset timeout with temperature-stable delay | Guaranteed hold time across −40°C to +105°C; avoids premature CPU release during cold-start or thermal cycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710EUT+T | Same package and pinout; monitors Adj/3.3V/2.5V/1.8V but with −10% tolerance on 1.8V rail | Suitable where looser 1.8V threshold margin is acceptable (e.g., non-critical auxiliary rails) | Select MAX6710EUT+T only if −10% 1.8V tolerance meets system margin requirements; otherwise MAX6710FUT+T provides tighter control. |
| TPS3808G33DBVR | Triple-monitor (not quad); fixed 3.3V threshold only; 200ms timeout; higher 45μA ICC | Lacks IN3/IN4 fixed-rail monitoring-requires external circuitry to cover 2.5V/1.8V rails | Use TPS3808G33DBVR only when monitoring only 3.3V plus two adjustable rails; MAX6710FUT+T integrates full quad coverage in same footprint. |
Compared with MAX6710EUT+T, MAX6710FUT+T offers tighter −5% tolerance on the 1.8V rail for improved margin in noise-prone environments; versus TPS3808G33DBVR, it delivers native quad-rail support without external components-reducing design complexity and board area.

FAQ
What is the exact reset timeout duration for MAX6710FUT+T?
The MAX6710FUT+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 −40°C to +105°C. This fixed delay ensures reliable CPU and peripheral initialization before system release, and is inherent to the MAX6710 variant-not adjustable externally.
Which supply rails does MAX6710FUT+T monitor, and how are they configured?
MAX6710FUT+T monitors four rails: IN1 (adjustable via external resistor divider, base threshold 0.62V), IN2 (3.3V, also powers the device), IN3 (2.5V, −5% tolerance), and IN4 (1.8V, −5% tolerance). Configuration is factory-trimmed-no external resistors needed for IN2–IN4. Top mark AAZF confirms this specific variant per the Selector Guide.
Does MAX6710FUT+T require an external pullup resistor on the RESET pin?
No, MAX6710FUT+T includes a 10μA internal pullup to IN2, making an external pullup unnecessary when interfacing with 3.3V logic. If driving a different logic voltage (e.g., 1.8V or 5V), an external pullup may be added-the internal pullup will not interfere due to reverse-current protection circuitry.
What is the operating voltage range for IN2 on MAX6710FUT+T?
For MAX6710FUT+T, IN2 operates from 1.2V to 5.5V across −40°C to +105°C. The RESET output remains valid as long as IN2 stays ≥1.0V, and the device draws only 35μA typical supply current-enabling use in low-voltage, low-power applications such as battery-backed controllers.
How does MAX6710FUT+T handle short voltage transients on monitored inputs?
MAX6710FUT+T is immune to transients ≤100µs in duration when the overdrive is ≥100mV below threshold-verified in Typical Operating Characteristics (Figure MAX6700 toc04). This prevents false resets caused by switching noise or load-step coupling, eliminating need for additional RC filtering on IN1–IN4 in most designs.
