Product details
Overview
MAX6710EUT-T from Maxim Integrated is a quad-voltage microprocessor supervisory IC in SOT23-6 package that monitors one adjustable (IN1), one fixed 3.3V (-10%), one fixed 2.5V (-10%), and one fixed 1.8V (-10%) supply rail, asserting an active-low open-drain RESET output when any falls below its threshold. It delivers 140ms minimum reset timeout, 0.62V internal reference accuracy for adjustable inputs, and operates from -40°C to +85°C. Used in desktop computers and industrial equipment for reliable power-on reset sequencing.
For engineers reviewing the MAX6710EUT-T datasheet, MAX6710EUT-T pinout, MAX6710EUT-T application, or MAX6710EUT-T equivalent, key selection criteria include factory-trimmed 3.3V/2.5V/1.8V thresholds with ±10% tolerance, 140ms reset timeout, 35μA quiescent current, IN2-powered operation, and guaranteed operation down to IN1/IN2 = 1V - critical for low-voltage, multi-rail embedded systems.
Technical Context
The MAX6710EUT-T implements four independent voltage comparators with a shared 0.62V bandgap reference and precision resistor-divider networks for fixed thresholds (3.3V, 2.5V, 1.8V at -10% tolerance) and direct comparator input for the adjustable IN1 channel. Each comparator includes 0.3% VTH hysteresis to reject noise-induced false resets.
Its reset logic uses a NOR-gated output with a dedicated 140ms timeout timer activated after all monitored voltages recover; the open-drain RESET output features a 10μA internal pullup to IN2, eliminating need for external pullup in many 3.3V logic interfaces while supporting overdrive to other logic rails up to 5.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | IN1: adjustable (0.62V ref); IN2: 3.3V (-10%); IN3: 2.5V (-10%); IN4: 1.8V (-10%) - enables precise multi-rail monitoring without external resistors for fixed rails |
| Reset Timeout | 140ms (min) - ensures stable processor initialization after brownout recovery in computing and industrial systems |
| Supply Current | 35μA (typ) - supports always-on supervision in battery-backed or low-power embedded applications |
| Input Voltage Range (IN1/IN3/IN4) | 0.611V to 0.629V threshold (adjustable inputs) - allows accurate scaling to monitor supplies ≥0.62V via external divider |

| Reset Validity Condition | RESET remains valid if IN1 ≥ 1V or IN2 ≥ 1V - maintains reset assertion during partial supply recovery |
Pinout & Package
MAX6710EUT-T is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), surface-mount, RoHS-compliant, tape-and-reel format. Pin 1 is IN1; Pin 2 is IN2 (power and monitored supply); Pin 3 is IN3; Pin 4 is IN4; Pin 5 is GND; Pin 6 is active-low open-drain RESET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable voltage monitor input | Connects directly to comparator input with 0.62V internal threshold; requires external resistor divider to monitor >0.62V supplies |
| 2 - IN2 | Power supply and monitored voltage input | Supplies device and monitors 3.3V (-10%); RESET valid as long as IN2 ≥ 1V |
| 3 - IN3 | Fixed-threshold monitor input | Factory-trimmed for 2.5V (-10%); no external components required |
| 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 monitored inputs and internal circuitry; must be low-impedance |
| 6 - RESET | Active-low open-drain reset output | Asserts low on any undervoltage event; remains low for 140ms min after recovery; 10μA internal pullup to IN2 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710DUT-T | Same pinout and package; monitors 5V (-5%), 3.3V (-5%), 1.8V (-5%), and adjustable IN1 - tighter ±5% tolerance on fixed rails | Better suited for 5V legacy bus interfaces and higher-precision 1.8V core rails where ±5% threshold accuracy is mandated | Select MAX6710DUT-T when system requires 5V monitoring and tighter threshold tolerance; MAX6710EUT-T preferred for 3.3V/2.5V/1.8V-only systems with ±10% margin |
| TPS3808G33DBVR | Triple-supply monitor (3.3V, 2.5V, 1.8V) with 200ms timeout; no adjustable input; different pinout (SOT23-6 but non-compatible) | Lacks fourth adjustable input; requires external resistor for any non-standard rail; lower quiescent current (1.5μA) but no IN1 flexibility | Choose TPS3808G33DBVR only if exactly three fixed rails are monitored and board layout allows rework; MAX6710EUT-T provides superior design flexibility with fourth adjustable channel |
Compared with MAX6710DUT-T, MAX6710EUT-T trades ±5% threshold accuracy for broader 2.5V/1.8V coverage at ±10%, while retaining identical 3.3V monitoring and adjustable IN1 - making it optimal for cost-sensitive, 3.3V-centric systems. Against TPS3808G33DBVR, MAX6710EUT-T adds critical fourth-rail flexibility and maintains compatibility with Maxim's established footprint and timing behavior.

FAQ
What is the exact reset timeout duration for MAX6710EUT-T?
The MAX6710EUT-T guarantees a minimum reset timeout period of 140ms after all monitored supply voltages rise above their respective thresholds. Typical timeout is 200ms, with a maximum of 280ms over temperature. This fixed delay ensures sufficient time for microprocessors, memory controllers, and PLLs to fully stabilize before release - a key requirement in x86 and ARM-based computing platforms where the MAX6710EUT-T is commonly deployed.
Does MAX6710EUT-T require an external pullup resistor on the RESET pin?
No, the MAX6710EUT-T includes a 10μA internal pullup to IN2, which is 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., 1.8V or 5V), in which case a resistor to that rail can safely overdrive the internal pullup without reverse current flow - a feature explicitly supported in the MAX6710EUT-T's design to simplify multi-voltage system integration.
Which supply rails does MAX6710EUT-T monitor, and how are they configured?
The MAX6710EUT-T monitors four rails: IN1 is adjustable (0.62V internal reference, scaled via external resistor divider); IN2 is factory-trimmed for 3.3V at -10% tolerance; IN3 for 2.5V at -10%; and IN4 for 1.8V at -10%. This configuration is fixed per the "E" suffix in the Selector Guide and cannot be altered. No external resistors are needed for the three fixed thresholds, reducing BOM count and layout complexity compared to fully adjustable solutions.
Can MAX6710EUT-T operate if only one monitored supply is present above 1V?
Yes - the MAX6710EUT-T guarantees RESET output validity as long as either IN1 ≥ 1V or IN2 ≥ 1V, even if IN3 or IN4 fall below their thresholds. This design allows continued reset assertion during partial brownout scenarios common in industrial power systems, ensuring the microprocessor remains held in reset until at least one primary supply recovers sufficiently to support basic logic operation - a critical reliability feature confirmed in the MAX6710EUT-T's absolute maximum ratings and electrical characteristics.
What is the operating temperature range and package type for MAX6710EUT-T?
The MAX6710EUT-T is rated for operation from -40°C to +85°C and is supplied in a RoHS-compliant 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm). It ships in tape-and-reel format with a 2500-piece minimum order quantity. The "-T" suffix denotes lead-free packaging, and the top mark "AAZE" uniquely identifies the MAX6710EUT-T variant per Maxim's Selector Guide - enabling unambiguous identification on PCBs and in inventory systems.
