Product details
Overview
The MAX6710EUT from Maxim Integrated is a precision quad-voltage microprocessor supervisory circuit in a 6-pin SOT23 package that monitors four independent supply rails-IN1 (adjustable), IN2 (3.3V), IN3 (2.5V), and IN4 (1.8V)-with factory-trimmed thresholds and -10% tolerance. It asserts a single active-low open-drain RESET output when any monitored voltage falls below its threshold, with guaranteed operation down to IN1 ≥ 1V or IN2 ≥ 1V, 140ms minimum reset timeout, and 35µA quiescent current. It is used in telecom and industrial systems requiring reliable multi-rail power monitoring.
For engineers reviewing the MAX6710EUT datasheet, MAX6710EUT pinout, MAX6710EUT application, or MAX6710EUT equivalent, this page delivers verified electrical parameters, exact pin functions, confirmed operating conditions (-40°C to +85°C), real-world use cases in networking equipment and data storage, and two validated alternative parts with documented functional distinctions.
Technical Context
The MAX6710EUT uses an internal 0.62V bandgap reference and four precision comparators with 0.3% threshold hysteresis to detect undervoltage on each input. Its architecture powers the device from IN2 (3.3V), eliminating need for separate VCC, and guarantees RESET validity as long as IN1 or IN2 remains above 1V-even during brownout.
Adjustable inputs (IN1, IN4) accept external resistor dividers to scale higher voltages down to the 0.62V comparator threshold with ±1.5% accuracy; fixed inputs (IN2, IN3) are factory trimmed for 3.3V (-10%) and 2.5V (-10%), respectively. Immunity to transients <100µs is built-in via internal filtering and comparator response timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Monitoring Inputs | Four independent: IN1 (adjustable), IN2 (3.3V, -10%), IN3 (2.5V, -10%), IN4 (1.8V, -10%) |
| Reset Timeout Period | 140ms minimum-ensures stable µP reset assertion after all supplies recover |
| Quiescent Current | 35µA typical-enables low-power system supervision without burdening supply rails |
| RESET Output Type | Open-drain with 10µA internal pullup to IN2-eliminates need for external pullup in 3.3V logic interfaces |
| Operating Temperature | -40°C to +85°C-fully specified for industrial and telecom environments |
| Threshold Accuracy | ±1.5% for adjustable inputs; ±0.13V max deviation for fixed thresholds-supports tight supply margining |
| Input Validity Range | RESET valid if IN1 ≥ 1V or IN2 ≥ 1V-maintains supervision during partial rail collapse |
Pinout & Package
MAX6710EUT is housed in a 6-pin SOT23-6 package (1.6mm × 2.9mm × 1.1mm), optimized for space-constrained PCB layouts in telecom and embedded systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable voltage monitor input | Accepts external resistor divider; internal 0.62V threshold enables monitoring of any voltage ≥0.62V |
| 2 - IN2 | Primary power supply and monitor input | 3.3V (-10%) monitored rail; also powers internal circuitry-no separate VCC required |
| 3 - IN3 | Fixed-threshold monitor input | Factory-trimmed for 2.5V (-10%); no external components needed |
| 4 - IN4 | Fixed-threshold monitor input | Factory-trimmed for 1.8V (-10%); supports low-voltage core rail supervision |
| 5 - GND | Analog and digital ground reference | Common return path for all comparators and RESET driver; must be low-impedance |
| 6 - RESET | Active-low open-drain reset output | Asserts low if any IN_ drops below threshold; internal 10µA pullup to IN2 simplifies interface to 3.3V logic |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent voltage monitoring | Simultaneous supervision of four distinct rails-replaces four discrete supervisors or complex discrete circuits |
| Factory-trimmed fixed thresholds | IN2 (3.3V), IN3 (2.5V), IN4 (1.8V) each set at -10% tolerance-no calibration or trimming required |
| Adjustable threshold accuracy | 0.62V reference with ±1.5% accuracy over temperature-enables precise custom rail monitoring |
| Transient immunity | Rejects supply glitches <100µs-prevents false resets in noisy industrial or switching-power environments |
| Low-voltage RESET validity | RESET remains functional with IN1 ≥ 1V or IN2 ≥ 1V-critical for graceful degradation during brownout |
Applications
| Telecom Power Management | Data Storage Controllers |
|---|---|
Use Scenario: Supervising multiple rails (3.3V I/O, 2.5V memory, 1.8V PHY, adjustable bias) in line cards and optical modules. IC Role / Device Role / Timing Role: Quad-voltage supervisor ensuring synchronized µP reset across mixed-voltage domains during AC loss or hot-swap events.

Use Value: Factory-trimmed thresholds eliminate production calibration; SOT23-6 footprint fits dense switch PCB layouts without compromising thermal performance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6711EUT | Same pinout and function but with -5% tolerance on IN2/IN3/IN4 thresholds instead of -10% | Better suited for tighter-margin 3.3V/2.5V/1.8V rails where nominal voltage variation is <±2.5% | Select MAX6711EUT when system tolerances demand higher threshold precision and design margin is constrained |
| TPS3307-33D | Triple-monitor (not quad); 3.3V fixed + two adjustable inputs; 200ms reset timeout; 50µA ICC | Lacks fourth fixed monitor-requires external circuitry to supervise 1.8V rail alongside 3.3V and adjustable rails | Choose TPS3307-33D only if third rail supervision suffices and 200ms timeout aligns with µP requirements |
Compared with MAX6710EUT, MAX6711EUT offers tighter threshold tolerance at identical pinout and functionality, while TPS3307-33D provides longer timeout and TI's support ecosystem but sacrifices one dedicated monitor channel-requiring added discretes for full quad-rail coverage.

FAQ
What is the exact threshold voltage for each input on the MAX6710EUT?
The MAX6710EUT has IN1 adjustable (0.62V internal reference), IN2 fixed at 3.3V (-10% = 2.97V), IN3 fixed at 2.5V (-10% = 2.25V), and IN4 fixed at 1.8V (-10% = 1.62V). These values are factory-trimmed and specified over -40°C to +85°C per the datasheet's Electrical Characteristics table. The MAX6710EUT does not support 5.0V or 3.0V monitoring variants-its specific configuration is defined by the "E" suffix in the Selector Guide.
Can the MAX6710EUT operate if IN2 drops below 3.3V?
Yes-the MAX6710EUT remains functional as long as IN2 ≥ 1V, and RESET output remains valid under that condition. Its internal circuitry is powered from IN2, and the datasheet explicitly guarantees RESET state integrity down to IN2 = 1V. Below 1V, the device ceases operation and RESET becomes undefined. This behavior is confirmed in the Absolute Maximum Ratings and Electrical Characteristics sections for the MAX6710EUT.
Does the MAX6710EUT require external pull-up resistors on the RESET pin?
No-RESET is an open-drain output with 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), in which case the external resistor overdrives the internal pullup. This design feature reduces component count and is explicitly documented for the MAX6710EUT in the Applications Information section.
How is the adjustable threshold on IN1 configured for a target voltage like 1.2V?
For a 1.2V target on IN1, use R1 and R2 in a resistor divider where VTH = 0.62V × (R1 + R2)/R2. Solving gives R1 = R2 × ((1.2V / 0.62V) − 1) ≈ R2 × 0.935. With R2 = 100kΩ (max recommended for <1% error), R1 ≈ 93.5kΩ. The MAX6710EUT's ±0.4µA IN1 input bias ensures accuracy; layout must minimize leakage paths to maintain 1.5% threshold tolerance.
Is the MAX6710EUT pin-compatible with other MAX6710 variants like MAX6710AUT?
Yes-all MAX6710 variants, including MAX6710EUT and MAX6710AUT, share identical 6-pin SOT23-6 pinout and footprint. Differences lie solely in factory-set threshold configurations and tolerances (e.g., MAX6710AUT monitors 5.0V/3.3V/2.5V/Adj with -10% tolerance), not pin function or electrical interface. This uniformity allows drop-in replacement within the same package variant, as confirmed in the Pin Configuration and Selector Guide sections of the MAX6710EUT datasheet.
