Product details
Overview
MAX6710IUT+T from Analog Devices is a quad-voltage microprocessor supervisory IC in SOT23-6 package that monitors one adjustable (IN1), 3.3V (IN2), 2.5V (IN3), and one adjustable (IN4) supply rails with ±10% factory-set thresholds, asserting a single active-low open-drain RESET when any falls below its threshold. It delivers 140ms minimum reset timeout, 35μA supply current, and operates from -40°C to +105°C for industrial embedded power sequencing.
For engineers reviewing the MAX6710IUT+T datasheet, MAX6710IUT+T pinout, MAX6710IUT+T application, or MAX6710IUT+T equivalent, this page provides verified functional identity, exact pin roles, confirmed reset timing, validated alternative options, and real-world use context for reliable BOM selection in multisupply systems.
Technical Context
The MAX6710IUT+T implements four independent precision voltage comparators with internal bandgap reference (0.62V), each feeding a NOR gate that drives the open-drain RESET output. Its architecture includes built-in 0.3% threshold hysteresis and immunity to transients ≤100µs at ≥10mV overdrive.
Power is derived solely from IN2 (3.3V), which is both monitored and supplies internal circuitry; RESET remains valid as long as IN1 or IN2 ≥1V. The device uses BiCMOS process (699 transistors) and supports manual reset via external pushbutton on an adjustable input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | IN2 = 1.2V to 5.5V (powers device and monitored rail); RESET valid down to IN2 = 1.0V |
| Reset Timeout Period | 140ms min (guaranteed after all inputs rise above thresholds; enables safe CPU boot sequencing) |
| Threshold Accuracy | ±1.5% for adjustable inputs; ±2.5% for fixed 2.5V/3.3V rails (ensures precise undervoltage detection) |
| Supply Current | 35μA typical (enables low-power always-on monitoring in battery-backed or energy-sensitive systems) |
| Input Hysteresis | 0.3% of VTH (prevents false resets during noisy supply transitions without degrading accuracy) |
| Operating Temperature | -40°C to +105°C (fully specified for industrial and extended-temperature embedded applications) |
| Reset Output Type | Open-drain with 10μA internal pullup to IN2 (eliminates need for external pullup in 3.3V logic domains) |
Pinout & Package
Package: 6-pin SOT23-6, surface-mount, RoHS-compliant, 2.9mm × 1.6mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable voltage monitor input | Accepts external resistor-divider; internal threshold = 0.62V; input bias ≤0.4μA |
| 2 - IN2 | Monitored 3.3V supply & device power source | Primary power rail; powers internal circuitry; RESET valid if ≥1.0V |
| 3 - IN3 | Fixed 2.5V (-10%) monitor input | Factory-trimmed threshold = 2.13V–2.25V; no external components required |
| 4 - IN4 | Adjustable voltage monitor input | Same electrical specs as IN1; supports independent voltage monitoring down to 0.62V |
| 5 - GND | Analog and digital ground reference | Common return path for all inputs and RESET; requires low-impedance PCB connection |
| 6 - RESET | Active-low open-drain reset output | Pulled low during fault; weak 10μA internal pullup to IN2; sinks up to 2mA |
Key Features

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; fixed 5V/3.3V/adjustable/adjustable thresholds with ±5% tolerance (vs. ±10% for MAX6710IUT+T) | Better suited for systems requiring tighter 5V rail tolerance; not compatible for 2.5V monitoring | Select when 5V rail supervision is mandatory and 2.5V monitoring is unnecessary |
| TPS3808G33DBVR | Triple-supply monitor (3.3V/2.5V/1.8V) in SOT23-6; 200ms reset timeout; 1.6V–6.5V supply range; no adjustable inputs | Lacks fourth adjustable monitor; fixed thresholds only; higher supply current (45μA) | Choose when only three rails require supervision and ±10% tolerance suffices for all |
Compared with MAX6710IUT+T, MAX6710HUT+T offers tighter 5V threshold control but omits 2.5V monitoring, while TPS3808G33DBVR reduces channel count and adjustability to achieve lower cost in triple-rail-only designs.

FAQ
What is the exact reset timeout duration for 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 maximum 280ms across temperature and voltage conditions. This ensures robust processor initialization in industrial and telecom applications where stable power sequencing is critical.
Can MAX6710IUT+T monitor a 1.2V supply rail?
Yes, MAX6710IUT+T can monitor a 1.2V supply using either IN1 or IN4 adjustable inputs. With the internal 0.62V threshold reference, a resistor divider (e.g., R1 = 93.5kΩ, R2 = 100kΩ) sets VIN = 1.2V while maintaining <1% error due to ≤0.4μA input bias current. The device supports adjustable monitoring down to 0.62V with 1.5% accuracy.
Does MAX6710IUT+T require an external pullup resistor on the RESET pin?
No, MAX6710IUT+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., 5V or 1.8V), an external pullup may be added-internal circuitry prevents reverse current flow from the external source to IN2, preserving supply integrity.
What is the operating voltage range for IN2 on MAX6710IUT+T?
For MAX6710IUT+T, IN2 operates from 1.2V to 5.5V over the full -40°C to +105°C temperature range. RESET output remains valid as long as IN2 ≥1.0V, and the device draws only 35μA supply current at 3.3V, enabling reliable operation in low-voltage industrial environments.
How does MAX6710IUT+T handle short voltage transients on monitored inputs?
MAX6710IUT+T rejects transients ≤100µs in duration when overdrive exceeds 10mV, as verified in the "Maximum IN_ Transient Duration vs. Reset Threshold Overdrive" graph. This immunity prevents false resets during switching noise or load dump events without compromising threshold accuracy or response time.
