Analog Devices Inc./Maxim Integrated MAX6710JUT-T

Overview

MAX6710JUT-T from Maxim Integrated is a precision quad-voltage microprocessor supervisory IC that monitors four supply rails-including adjustable thresholds on IN1, IN3, and IN4, and a fixed 3.3V threshold on IN2-with ±5% tolerance. It asserts an active-low open-drain RESET output when any monitored voltage falls below its threshold and maintains reset for ≥140ms after all voltages recover. Designed for embedded power integrity in space-constrained systems like servers and networking equipment.

For engineers reviewing the MAX6710JUT-T datasheet, MAX6710JUT-T pinout, MAX6710JUT-T application, or MAX6710JUT-T equivalent, this device delivers verified low-power supervision (35μA), factory-trimmed 3.3V/2.5V monitoring, sub-1V valid operation, and immunity to short transients-key selection criteria for reliable system boot and brownout protection.

Technical Context

The MAX6710JUT-T implements four independent voltage comparators with a shared 0.62V internal reference and precision resistor-divider networks for fixed thresholds. Its architecture includes built-in 0.3% threshold hysteresis and a dedicated 140ms timeout timer that holds RESET low after recovery-distinct from the MAX6700's 5μs propagation delay.

IN2 serves as both power supply and monitored input (3.3V, −5%), while IN1, IN3, and IN4 are adjustable inputs supporting down-to-0.62V thresholds via external dividers. The open-drain RESET output features a 10μA internal pullup to IN2 and remains valid as long as IN1 or IN2 ≥1.0V, enabling robust operation during partial rail collapse.

FAQ

What is the reset timeout period for MAX6710JUT-T?

The MAX6710JUT-T provides a guaranteed minimum reset timeout period of 140ms after all monitored voltages rise above their respective thresholds. This ensures sufficient hold time for processor initialization, memory training, and peripheral configuration before release. The typical timeout is 200ms, and maximum is 280ms across temperature and voltage conditions-fully specified in the Electrical Characteristics table of the MAX6710JUT-T datasheet.

Which supply rails does MAX6710JUT-T monitor, and what are their thresholds?

The MAX6710JUT-T monitors four rails: IN1 and IN4 are adjustable inputs (threshold set by external resistor divider referenced to 0.62V), IN2 is fixed at 3.3V with −5% tolerance (3.15V typical threshold), and IN3 is fixed at 2.5V with −5% tolerance (2.38V typical threshold). These values are confirmed in the Selector Guide and Electrical Characteristics tables for MAX6710JUT-T.

Does MAX6710JUT-T require external pull-up resistors on the RESET pin?

No, the MAX6710JUT-T includes a 10μA internal pullup to IN2 on its open-drain RESET pin, eliminating the need for an external pullup in standard 3.3V logic interfaces. An external pullup may be added only when interfacing with logic supplies outside the IN2 voltage range (e.g., 1.8V or 5V), and internal circuitry prevents reverse current flow from the external source to IN2.

What is the operating voltage range for MAX6710JUT-T's monitored inputs?

The MAX6710JUT-T operates with IN1, IN3, and IN4 inputs functional from 0.62V up to 5.5V, and IN2 (which also powers the device) functional from 1.0V to 5.5V. RESET remains valid as long as either IN1 or IN2 is ≥1.0V-enabling reliable supervision during partial power-up sequences where some rails may be absent or collapsed.

How does MAX6710JUT-T handle short voltage transients on monitored inputs?

The MAX6710JUT-T is specifically designed to reject short transients: it ignores IN_ voltage dips lasting less than ~100µs when the overdrive is ≤50mV, as shown in the "Maximum IN_ Transient Duration vs. Reset Threshold Overdrive" graph. This immunity prevents false resets caused by switching noise, ESD coupling, or load-step artifacts in industrial and telecom power systems.
