Product details
Overview
MAX6710IUT-T from Maxim Integrated is a precision quad-voltage microprocessor supervisory IC that monitors four supply rails-including adjustable thresholds on IN1, IN3, and IN4, and a fixed 3.3V threshold on IN2-with -10% tolerance. It asserts an active-low open-drain RESET output when any monitored voltage falls below its threshold and holds reset for ≥140ms after all supplies recover. Used in servers and industrial embedded systems to ensure reliable power-on sequencing and brownout protection.
For engineers reviewing the MAX6710IUT-T datasheet, MAX6710IUT-T pinout, MAX6710IUT-T application, or MAX6710IUT-T equivalent, key selection criteria include its 3.3V/2.5V/adjustable triple-threshold configuration, 140ms reset timeout, 35μA quiescent current, SOT23-6 package, and guaranteed operation from -40°C to +85°C.
Technical Context
The MAX6710IUT-T implements four independent voltage comparators with a shared 0.62V internal reference and factory-trimmed resistor dividers for fixed thresholds (IN2 = 3.3V, IN3 = 2.5V), while IN1 and IN4 accept externally scaled inputs via resistor dividers. Its NOR-gated reset logic ensures single-point fault detection across all monitored rails.
Reset assertion is synchronized to input voltage decay with 30μs typical delay, and deassertion includes a guaranteed 140ms minimum timeout period-critical for ensuring stable CPU initialization. The device remains functional with IN1 or IN2 ≥1.0V, enabling robust operation during partial power-up sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | IN1: adjustable (0.62V ref), IN2: fixed 3.3V (-10%), IN3: fixed 2.5V (-10%), IN4: adjustable - enables flexible multi-rail monitoring |
| Reset Timeout Period | 140ms min - ensures sufficient hold time for CPU and FPGA configuration after power stabilization |
| Supply Current | 35μA typ - supports ultra-low-power battery-backed or always-on monitoring applications |
| Input Threshold Accuracy | ±1.5% for adjustable inputs, ±1.3% for fixed 3.3V/2.5V - guarantees precise undervoltage detection without calibration |
| Operating Temperature | -40°C to +85°C - qualified for industrial and commercial embedded environments |
| RESET Output Type | Open-drain with 10μA internal pullup to IN2 - eliminates need for external pullup in 3.3V systems |
| Propagation Immunity | Immune to transients <100μs at 50mV overdrive - rejects noise spikes without false resets |
Pinout & Package
MAX6710IUT-T is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), optimized for space-constrained PCB layouts in computing and telecom equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable voltage monitor input | Accepts external resistor divider; threshold set by VTH = 0.62V × (R1+R2)/R2 - supports monitoring of any rail ≥0.62V |
| 2 - IN2 | Fixed 3.3V supply monitor & power source | Monitors 3.3V rail with -10% threshold (2.97V); also powers internal circuitry - no separate VCC required |
| 3 - IN3 | Fixed 2.5V supply monitor | Factory-trimmed for 2.5V (-10% = 2.25V) - eliminates external components for standard core voltage supervision |
| 4 - IN4 | Adjustable voltage monitor input | Same architecture as IN1; enables dual adjustable rails (e.g., 1.2V + 1.8V) using external dividers |
| 5 - GND | Analog and digital ground reference | Single ground connection for all comparators and reset logic - requires low-impedance layout for noise immunity |
| 6 - RESET | Active-low open-drain reset output | Pulled low on fault; weak 10μA internal pullup to IN2 - interfaces directly with 3.3V µP reset inputs without external components |
Key Features
| Feature | Design Value |
|---|---|
| Quad-supply monitoring in SOT23-6 | Replaces four discrete supervisors or larger multi-channel ICs - reduces board area by >60% vs. discrete solutions |
| Factory-fixed + adjustable thresholds | IN2 (3.3V) and IN3 (2.5V) require zero external parts; IN1/IN4 support custom rails down to 0.62V with <1% resistor error margin |
| 140ms minimum reset timeout | Guarantees CPU reset hold time exceeds boot ROM access latency and PLL lock times in x86 and ARM platforms |
| 1.0V input validity limit | RESET remains asserted and valid even if IN1 or IN2 drops to 1.0V - supports graceful degradation during partial power loss |
| 0.3% threshold hysteresis | Prevents chatter during slow supply recovery without sacrificing accuracy - eliminates need for external hysteresis networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710HUT-T | Same package and pinout; IN2=3.3V (-5%), IN3=2.5V (-5%), IN1/IN4 adjustable - tighter 5% tolerance on fixed rails | Better suited for systems requiring higher reset threshold precision on 3.3V/2.5V rails, e.g., high-speed memory interfaces | Select MAX6710HUT-T when ±0.15V tighter threshold tolerance is required on IN2/IN3 versus MAX6710IUT-T's ±0.33V/±0.25V |
| TPS3808G33DBVR | Triple-supply monitor (3.3V/adj/adj); no IN3 2.5V fixed option; 200ms timeout; 1.8V–6.5V VDD range | Lacks native 2.5V rail monitoring - requires external divider for 2.5V, increasing BOM count and error budget | Choose TPS3808G33DBVR only if 3.3V + two adjustable rails suffice and TI's 200ms timeout aligns better with system boot timing |
Compared with MAX6710HUT-T, the MAX6710IUT-T trades tighter fixed-rail tolerance for broader compatibility with legacy 2.5V/3.3V systems where -10% margins are standard; versus TPS3808G33DBVR, it delivers integrated 2.5V supervision without external components but lacks a wider VDD operating range.

FAQ
What is the exact reset timeout duration of the MAX6710IUT-T?
The MAX6710IUT-T guarantees a minimum reset timeout period of 140ms after all monitored voltages rise above their thresholds. Typical duration is 200ms, with a maximum of 280ms across temperature and voltage ranges. This timing ensures reliable CPU and FPGA initialization in servers and industrial controllers where boot firmware requires extended reset hold times before executing code.
Which supply rails does the MAX6710IUT-T monitor by default, and how are they configured?
The MAX6710IUT-T monitors four rails: IN2 is factory-set to 3.3V with -10% tolerance (2.97V threshold), IN3 is fixed at 2.5V with -10% tolerance (2.25V), and IN1/IN4 are adjustable inputs referenced to 0.62V - each requiring an external resistor divider to scale higher voltages. This configuration matches common compute platform rails without external components for IN2/IN3.
Does the MAX6710IUT-T require an external pullup resistor on the RESET pin?
No, the MAX6710IUT-T includes a 10μA internal pullup to IN2, making an external pullup unnecessary in 3.3V systems. If interfacing with logic running at a different voltage (e.g., 1.8V or 5V), an external pullup to that rail is required - the internal pullup is automatically overridden, and reverse current flow is blocked by internal circuitry.
Can unused inputs on the MAX6710IUT-T be left floating?
No - unused inputs must not float. For unused adjustable inputs (IN1 or IN4), connect a 1MΩ resistor from the pin to IN2. For unused fixed inputs, tie to a supply voltage exceeding the threshold (e.g., connect unused IN3 to 3.3V). Floating inputs cause unpredictable comparator behavior and potential false resets, compromising system reliability.
What is the minimum operating voltage required for the MAX6710IUT-T to maintain valid RESET output state?
The MAX6710IUT-T maintains valid RESET output as long as either IN1 or IN2 remains ≥1.0V. This allows continued reset assertion during partial power loss scenarios - for example, if IN2 (3.3V rail) sags to 1.2V while IN1 remains at 1.8V, RESET stays low and functional, supporting fail-safe shutdown protocols in industrial systems.
