Analog Devices Inc./Maxim Integrated MAX6710JUT+T

Overview

MAX6710JUT+T from Analog Devices is a quad-voltage microprocessor supervisory IC that monitors four supply rails-including adjustable thresholds on IN1 and IN4-and asserts a single active-low open-drain RESET output when any falls below its preset threshold. It features factory-trimmed 3.3V (−5%) and 2.5V (−5%) thresholds on IN2 and IN3, 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 MAX6710JUT+T datasheet, MAX6710JUT+T pinout, MAX6710JUT+T application, or MAX6710JUT+T equivalent, this page delivers verified electrical parameters, precise pin functions, real-world use cases in telecom and industrial systems, and two validated alternative parts with documented functional differences-enabling confident selection without cross-referencing external sources.

Technical Context

The MAX6710JUT+T implements four independent voltage comparators tied to an internal 0.62V bandgap reference, with resistor-divider networks setting fixed thresholds on IN2 (3.3V, −5%) and IN3 (2.5V, −5%), while IN1 and IN4 accept externally scaled inputs down to 0.62V. Each comparator includes 0.3% hysteresis to suppress noise-induced false resets.

Its RESET output remains asserted low for ≥140ms after all monitored voltages recover above their thresholds, ensuring reliable processor initialization. The open-drain output has a 10μA internal pullup to IN2, and RESET validity is guaranteed as long as IN1 or IN2 ≥1.0V-enabling operation during brownout conditions where VCC may be unstable.

FAQ

What is the exact reset timeout duration for MAX6710JUT+T?

The MAX6710JUT+T guarantees a minimum reset timeout period of 140ms after all monitored voltages rise above their thresholds, with typical value of 200ms and maximum of 280ms across temperature. This fixed delay ensures reliable microprocessor initialization and is not user-adjustable. The timeout is generated internally and does not require external components.

Can MAX6710JUT+T monitor a 1.2V supply rail?

Yes, MAX6710JUT+T can monitor a 1.2V rail using either IN1 or IN4, both configured as adjustable inputs with a 0.62V internal threshold. A resistor divider (e.g., R1 = 93.5kΩ, R2 = 100kΩ) scales the 1.2V input to 0.62V at the comparator, achieving ±1.5% accuracy. Input bias current remains below ±0.4μA, minimizing divider error.

Does MAX6710JUT+T require an external pullup resistor on the RESET pin?

No, MAX6710JUT+T includes a 10μA internal pullup to IN2, eliminating the need for an external pullup in standard 3.3V logic interfaces. An external pullup is only required when interfacing with logic supplies outside the IN2 voltage range (e.g., 1.8V or 5.0V), and must be sized to override the internal current without exceeding 20mA sink capability.

What is the operating voltage range for IN2 on MAX6710JUT+T?

For MAX6710JUT+T, IN2 operates from 1.0V to 5.5V and serves both as the monitored 3.3V (−5%) supply and the primary power source for the IC. RESET remains valid as long as IN2 ≥1.0V, enabling supervision during brownout conditions where the 3.3V rail dips but stays above 1V-critical for fail-safe behavior in industrial systems.

How does MAX6710JUT+T handle short-duration supply transients?

MAX6710JUT+T rejects transients shorter than 100µs due to built-in glitch immunity circuitry, as confirmed by the "Maximum IN_ Transient Duration vs. Reset Threshold Overdrive" graph in the datasheet. This prevents false resets from ESD events or switching noise, eliminating the need for external RC filters in most applications while maintaining ±1.5% threshold accuracy.
