Analog Devices Inc./Maxim Integrated MAX6710DUT+T

Overview

MAX6710DUT+T from Analog Devices is a quad-voltage microprocessor supervisory IC that monitors 5.0V, 3.3V, 1.8V (−5% tolerance), and one adjustable supply down to 0.62V, asserting a single active-low open-drain RESET output when any threshold is violated. It operates from −40°C to +105°C in a 6-pin SOT23 package with 140ms minimum reset timeout, 35μA supply current, and guaranteed validity of RESET as long as IN1 or IN2 ≥ 1V.

For engineers reviewing the MAX6710DUT+T datasheet, MAX6710DUT+T pinout, MAX6710DUT+T application, or MAX6710DUT+T equivalent, this device serves as a precision, low-power system integrity monitor for multi-rail embedded systems requiring deterministic reset timing, high-accuracy undervoltage detection, and immunity to short supply transients.

Technical Context

The MAX6710DUT+T implements four independent voltage comparators with factory-trimmed thresholds for 5.0V (−5%), 3.3V (−5%), and 1.8V (−5%), plus one adjustable input referenced to a 0.62V internal bandgap. Each comparator includes 0.3% VTH hysteresis to suppress noise-induced false resets.

Its RESET output remains asserted for a guaranteed minimum 140ms after all monitored supplies exceed their thresholds, with propagation delay tightly controlled across temperature (±60 ppm/°C TCVTH). Power is derived from IN2 (3.3V), which is both supply and monitored rail - RESET validity is maintained down to IN2 = 1.0V.

FAQ

What is the exact reset timeout duration for MAX6710DUT+T?

The MAX6710DUT+T guarantees a minimum reset timeout period of 140ms after all monitored supplies rise above their thresholds. Typical duration is 200ms, with a maximum of 280ms over temperature and process variation. This timing is internally generated and does not require external components, ensuring consistent reset hold time across all operating conditions for the MAX6710DUT+T.

Which supply rails does MAX6710DUT+T monitor, and what are their thresholds?

The MAX6710DUT+T monitors four rails: IN1 at 5.0V (−5%, 4.50V min), IN2 at 3.3V (−5%, 3.15V min), IN3 at 1.8V (−5%, 1.62V min), and IN4 as an adjustable input with 0.62V internal reference. The top mark AAZD confirms this specific configuration. All thresholds are factory-trimmed and specified over −40°C to +105°C for the MAX6710DUT+T.

Can MAX6710DUT+T operate if IN2 drops below 3.3V?

Yes - the MAX6710DUT+T maintains valid RESET assertion as long as IN2 remains ≥1.0V. Its internal circuitry ensures correct output state down to this level, enabling robust operation during brown-out conditions. Below 1.0V, RESET behavior is undefined; however, the device remains functional once IN2 recovers above 1.0V, making the MAX6710DUT+T suitable for systems with marginal 3.3V regulation.

Does MAX6710DUT+T require external components for basic operation?

No - the MAX6710DUT+T requires no external resistors or capacitors for its fixed-threshold monitoring of 5.0V, 3.3V, and 1.8V rails. Only the adjustable IN4 input needs an external resistor divider to set custom thresholds. The open-drain RESET output includes a 10μA internal pullup to IN2, eliminating the need for an external pullup in standard 3.3V logic interfaces for the MAX6710DUT+T.

How is the adjustable threshold on IN4 implemented in MAX6710DUT+T?

The MAX6710DUT+T uses an internal 0.62V precision bandgap reference at IN4. To monitor a higher voltage (e.g., 1.2V), connect an external resistor divider such that V_IN4 = 0.62V when the target rail reaches its threshold. The formula is R1 = R2 × ((V_TH/0.62V) − 1), with R2 ≤ 100kΩ to limit error from ±0.2μA input bias current - a key design feature of the MAX6710DUT+T.
