Analog Devices Inc./Maxim Integrated MAX6710GUT-T

Overview

MAX6710GUT-T from Maxim Integrated is a precision quad-voltage microprocessor supervisory IC that monitors 5.0V, 3.3V, and two adjustable thresholds (down to 0.62V) with ±5% tolerance on fixed thresholds and 1.5% accuracy on adjustable ones; it asserts an active-low open-drain RESET output for ≥140ms after all supplies recover, and operates from -40°C to +85°C in SOT23-6 packaging for embedded power sequencing in servers and industrial controllers.

For engineers reviewing the MAX6710GUT-T datasheet, MAX6710GUT-T pinout, MAX6710GUT-T application, or MAX6710GUT-T equivalent, key selection criteria include factory-trimmed 5.0V/3.3V monitoring, dual adjustable inputs, 140ms reset timeout, 35μA supply current, and guaranteed operation down to IN1/IN2 = 1V - critical for low-voltage, noise-immune system reset integrity.

Technical Context

The MAX6710GUT-T integrates four independent voltage comparators with a shared 0.62V internal reference and factory-trimmed resistor-divider networks for its 5.0V and 3.3V inputs, while two inputs (IN3 and IN4) accept externally scaled thresholds via resistor dividers. Each comparator features 0.3% threshold hysteresis to reject transient noise without degrading accuracy.

Its RESET output is open-drain with a 10μA internal pullup to IN2, remains asserted for a minimum 140ms timeout after all monitored voltages exceed their thresholds, and stays valid as long as IN1 or IN2 ≥ 1V - enabling reliable reset assertion during brown-out recovery in multi-rail systems.

FAQ

What is the exact reset timeout duration specified for MAX6710GUT-T?

The MAX6710GUT-T guarantees a minimum reset timeout period of 140ms after all monitored voltages rise above their respective thresholds. Typical duration is 200ms, with a maximum of 280ms over temperature. This fixed delay ensures sufficient hold time for microprocessors and FPGAs to complete internal initialization before release, and is inherent to the MAX6710 family - not programmable or adjustable in MAX6710GUT-T.

Which voltage rails does MAX6710GUT-T monitor by default, and how are they configured?

The MAX6710GUT-T monitors 5.0V (-10% threshold = 4.25V) on IN1, 3.3V (-10% threshold = 2.85V) on IN2, and two adjustable thresholds on IN3 and IN4 - each referenced to a precise 0.62V internal comparator input. No external components are needed for the fixed rails; IN3 and IN4 require external resistor dividers to scale higher voltages down to 0.62V, per the formula R1 = R2 × (V_{IN_TH}/0.62V − 1).

Can MAX6710GUT-T operate if one monitored supply drops below 1.0V?

Yes - the MAX6710GUT-T maintains valid RESET output state as long as either IN1 or IN2 remains ≥1.0V. If both fall below 1.0V, RESET becomes undefined. This feature allows reliable reset assertion during partial brown-out events, such as when only the 5V rail collapses while the 3.3V rail sustains at 1.2V, ensuring continued system control integrity in MAX6710GUT-T-based designs.

What is the purpose of the 10μA internal pullup on the RESET pin of MAX6710GUT-T?

The 10μA internal pullup on the MAX6710GUT-T's RESET pin connects to IN2, eliminating the need for an external pullup resistor in most 3.3V logic interfaces. It ensures clean high-state assertion when RESET is deasserted, supports interfacing with diverse logic families (1.8V–5.5V), and prevents floating states during power-up. External pullups may be added to override this internal source when interfacing with higher-voltage logic domains.

Does MAX6710GUT-T support manual reset functionality?

Yes - MAX6710GUT-T supports manual reset via its adjustable inputs (IN3 or IN4). Connecting a pushbutton between an adjustable input and ground initiates a RESET pulse; the switch must remain open for ≥140ms to deassert RESET. No external debounce components are required, and a small capacitor can be added for noise immunity on long button traces - a documented capability confirmed in the MAX6710 functional diagram and Applications Information section.
