Analog Devices Inc./Maxim Integrated MAX6710CUT-T

Overview

MAX6710CUT-T from Maxim Integrated is a quad-voltage microprocessor supervisory IC that monitors 5.0V (−10%), 3.3V (−10%), 1.8V (−10%), and one adjustable input down to 0.62V, asserting a single active-low open-drain RESET output when any threshold is violated. It operates from IN2 (1.2V–5.5V), consumes only 35μA, and delivers 140ms minimum reset timeout - ideal for power sequencing in desktop computers and industrial equipment.

For engineers reviewing the MAX6710CUT-T datasheet, MAX6710CUT-T pinout, MAX6710CUT-T application, or MAX6710CUT-T equivalent, key selection criteria include factory-trimmed −10% thresholds on three fixed rails, adjustable fourth input with 1.5% accuracy, guaranteed operation from −40°C to +85°C, and SOT23-6 package compatibility with space-constrained embedded designs.

Technical Context

The MAX6710CUT-T integrates four independent voltage comparators with a shared 0.62V bandgap reference and internal resistor-divider networks for fixed thresholds. Each comparator features 0.3% VTH hysteresis to suppress noise-induced false resets.

Its RESET output remains asserted for ≥140ms after all monitored voltages recover, ensuring reliable μP initialization. The open-drain output includes a 10μA internal pullup to IN2, eliminating need for external pullup in many 3.3V logic interfaces while supporting overdrive to 0–5.5V logic supplies.

Key Specifications

Pinout & Package

FAQ

What is the exact reset threshold voltage for each monitored input on the MAX6710CUT-T?

The MAX6710CUT-T has factory-trimmed thresholds: IN1 = 4.50V (5.0V × −10%), IN2 = 2.97V (3.3V × −10%), IN3 = 1.62V (1.8V × −10%), and IN4 = 0.62V (adjustable via external resistor divider). These values are guaranteed over −40°C to +85°C per the datasheet's Electrical Characteristics table, with ±1.3% max deviation for fixed thresholds and ±1.5% for adjustable inputs.

Does the MAX6710CUT-T require an external pullup resistor on the RESET pin?

No - the MAX6710CUT-T includes 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), and must be sized to overdrive the internal current without exceeding 20mA sink rating.

Can the MAX6710CUT-T monitor a 2.5V supply?

No - the MAX6710CUT-T variant is configured for 5.0V/3.3V/1.8V fixed thresholds and one adjustable input. To monitor 2.5V, use MAX6710AUT-T (5V/3.3V/2.5V/Adj) or MAX6710BUT-T (same with −5% tolerance). The C suffix explicitly denotes 1.8V on IN3 per the Selector Guide top mark AAZC.

What is the minimum valid voltage on IN2 for the MAX6710CUT-T to assert a valid RESET signal?

The MAX6710CUT-T guarantees correct RESET state down to IN2 = 1.2V at −40°C to +85°C (per Absolute Maximum Ratings and Electrical Characteristics). Below 1.2V, RESET may become indeterminate; operation is fully specified only above this level, and the output remains valid as long as IN2 ≥ 1.2V or IN1 ≥ 1.0V.

How does the MAX6710CUT-T handle short voltage transients on monitored inputs?

The MAX6710CUT-T rejects transients ≤100µs duration when overdrive is ≥50mV below threshold (per Typical Operating Characteristics graph "MAXIMUM IN_ TRANSIENT DURATION vs. RESET THRESHOLD OVERDRIVE"). This built-in immunity prevents false resets during switching noise or load-dump events without requiring external RC filtering.
