Product details
Overview
MAX6710OUT+T from Analog Devices is a quad-voltage microprocessor supervisory IC that monitors four system supply rails-including 5.0V, 3.3V, 2.5V, and one adjustable input-and asserts a single active-low RESET output if any falls below its preset threshold. It features factory-trimmed -10% tolerance thresholds, 140ms minimum reset timeout, 35μA supply current, and operates from -40°C to +105°C in a 6-pin SOT23 package for embedded power integrity monitoring.
For engineers reviewing the MAX6710OUT+T datasheet, MAX6710OUT+T pinout, MAX6710OUT+T application, or MAX6710OUT+T equivalent, this device serves as a precision, low-power, quad-supply monitor with fixed 5.0V/3.3V/2.5V thresholds and one adjustable channel-critical for reliable reset sequencing in telecom, industrial, and computing systems where multi-rail stability must be verified before processor boot.
Technical Context
The MAX6710OUT+T implements four independent voltage comparators referenced to a stable 0.62V internal bandgap, with three factory-set thresholds (5.0V, 3.3V, 2.5V at -10% tolerance) and one adjustable input. Its NOR-gated reset logic ensures assertion when any monitored rail fails, and its internal 140ms timeout counter guarantees sustained reset hold-off after recovery.
Power is derived from IN2 (3.3V), which also serves as a monitored rail; RESET remains valid as long as IN1 or IN2 ≥ 1.0V. The open-drain output includes a 10μA internal pullup to IN2 and supports external pullup to voltages up to 5.5V without reverse current flow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | 5.0V (-10%), 3.3V (-10%), 2.5V (-10%), and one adjustable input (threshold = 0.62V × (R1+R2)/R2) |
| Reset Timeout Period | 140ms minimum - ensures sufficient hold time for CPU initialization and peripheral stabilization |
| Supply Current | 35μA typical - enables use in always-on, battery-backed, or low-power standby circuits |
| Operating Temperature | -40°C to +105°C - qualified for industrial and extended-temperature embedded applications |
| Input Threshold Accuracy | ±1.5% for adjustable inputs; ±1.3% typical for factory-set rails - minimizes false resets under nominal supply variation |
| Reset Output Type | Open-drain with 10μA internal pullup to IN2 - eliminates need for external pullup in many 3.3V logic interfaces |
| Immunity to Transients | Rejects <100µs supply glitches - prevents spurious resets during switching noise or load transients |
Pinout & Package
MAX6710OUT+T is housed in a 6-pin SOT23 package (outline 21-0058), with footprint code U6+1 and RoHS-compliant lead finish. Pin 1 is IN1 (5.0V monitor), Pin 2 is IN2 (3.3V monitor and power source), Pin 3 is IN3 (2.5V monitor), Pin 4 is IN4 (adjustable input), Pin 5 is GND, and Pin 6 is RESET (active-low open-drain).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Fixed 5.0V (-10%) monitor input | Asserts reset if VIN1 < 4.50V; internally trimmed resistor divider scales to 0.62V reference |
| 2 - IN2 | Fixed 3.3V (-10%) monitor input and primary power supply | Supplies internal circuitry; reset remains valid if VIN2 ≥ 1.0V; also monitored for undervoltage |
| 3 - IN3 | Fixed 2.5V (-10%) monitor input | Asserts reset if VIN3 < 2.25V; uses same precision comparator architecture as IN1/IN2 |
| 4 - IN4 | Adjustable threshold input | Threshold = 0.62V at pin; external resistor divider sets monitored voltage (e.g., 1.8V, 1.2V, etc.) |
| 5 - GND | Analog and digital ground reference | Common return for all comparators and reset logic; requires low-impedance connection to system ground plane |
| 6 - RESET | Active-low open-drain reset output | Pulled low on fault; weak 10μA internal pullup to IN2; sinks up to 2mA; compatible with 1.8V–5.5V logic families |
Key Features
| Feature | Design Value |
|---|---|
| Quad-supply monitoring with mixed fixed/adjustable thresholds | Enables full-system rail supervision (e.g., 5V I/O, 3.3V core, 2.5V analog, 1.8V memory) in one 6-pin IC |
| Factory-trimmed -10% tolerance thresholds | Guarantees reset assertion at 4.50V (5V rail), 2.97V (3.3V rail), and 2.25V (2.5V rail) across temperature and process |
| 140ms minimum reset timeout | Meets JEDEC JESD78 reliability requirements for microprocessor reset hold time after power recovery |
| 10μA internal RESET pullup | Eliminates external pullup resistor in 3.3V systems, reducing BOM count and board area |
| 0.3% threshold hysteresis | Prevents chatter during slow-rising/falling supply edges without degrading accuracy |
Applications
| Telecom Power Management | Industrial PLC Controller |

Use Value: Enables graceful failover and logging during multi-rail brownouts without BMC lockup or watchdog timeout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710AUT+T | Same package and pinout; monitors 5.0V (-10%), 3.3V (-10%), 2.5V (-10%), and adjustable input - identical threshold set to MAX6710OUT+T per Selector Guide | No functional difference; top mark AAZA confirms identical configuration | Select MAX6710AUT+T only if top-mark traceability or legacy ordering codes are required |
| TPS3808G33DBVR | Triple-monitor (not quad); fixed 3.3V threshold only; no adjustable input; 200ms timeout; higher 60μA quiescent current | Lacks fourth rail monitoring and adjustable channel - unsuitable for systems requiring 5V/2.5V/auxiliary rail coverage | Use only when exactly three rails must be supervised and 5V/2.5V monitoring is handled externally |
Compared with MAX6710OUT+T, MAX6710AUT+T is functionally identical and interchangeable, while TPS3808G33DBVR offers longer timeout but sacrifices quad monitoring and adjustable flexibility-making it a partial substitute only in simplified dual- or triple-rail designs.

FAQ
What is the exact reset timeout duration for MAX6710OUT+T?
The MAX6710OUT+T provides a guaranteed minimum reset timeout period of 140ms after all monitored voltages rise above their thresholds. Typical timeout is 200ms, with a maximum of 280ms over temperature. This fixed delay is implemented via an internal timer and does not require external components.
Which supply rails does MAX6710OUT+T monitor, and what are their thresholds?
The MAX6710OUT+T monitors four rails: IN1 at 5.0V (-10% = 4.50V), IN2 at 3.3V (-10% = 2.97V), IN3 at 2.5V (-10% = 2.25V), and IN4 as an adjustable input with a 0.62V internal reference. External resistor dividers on IN4 allow monitoring of voltages such as 1.8V or 1.2V with ±1.5% accuracy.
Does MAX6710OUT+T require an external pullup resistor on the RESET pin?
No, MAX6710OUT+T includes a 10μA internal pullup to IN2, making an external pullup unnecessary in standard 3.3V logic interfaces. However, if interfacing with a different logic supply (e.g., 1.8V or 5V), an external pullup to that voltage is recommended - the internal pullup will not interfere due to reverse-current protection.
Can MAX6710OUT+T operate if one monitored input drops below 1.0V?
Yes - MAX6710OUT+T maintains valid RESET output state as long as either IN1 or IN2 remains ≥ 1.0V. If both fall below 1.0V, RESET behavior is undefined. This design ensures robustness during partial rail failures common in multi-supply systems.
What is the operating voltage range for the IN2 supply of MAX6710OUT+T?
The IN2 supply for MAX6710OUT+T operates from 1.2V to 5.5V over the full -40°C to +105°C temperature range. At room temperature, the lower limit is 1.0V. IN2 powers the device and is itself monitored; it must remain ≥ 1.0V (or ≥ 1.2V over full temp range) to guarantee RESET validity.
