Analog Devices Inc. ADM6710LARJZ-REEL7

Overview

ADM6710LARJZ-REEL7 from Analog Devices is a low-voltage, high-accuracy quad-supply supervisory IC that monitors four independent power rails - IN1 (adjustable), IN2 = 3.3 V, IN3 = 1.8 V, and IN4 (adjustable) - with factory-trimmed thresholds and ±5% tolerance. It delivers active-low open-drain RESET with 200 ms typical timeout, operates from −40°C to +125°C, and draws only 35 µA, making it suitable for space-constrained, high-reliability embedded microprocessor systems.

For engineers reviewing the ADM6710LARJZ-REEL7 datasheet, ADM6710LARJZ-REEL7 pinout, ADM6710LARJZ-REEL7 application, or ADM6710LARJZ-REEL7 equivalent, key selection considerations include its 6-lead SOT-23 package, guaranteed RESET validity down to IN1 or IN2 = 1 V, adjustable 0.62 V reference with 1.5% accuracy, and immunity to supply glitches in telecom and server power monitoring.

Technical Context

The ADM6710LARJZ-REEL7 implements four independent voltage comparators tied to a shared 0.62 V internal reference, with IN2 serving as both power source and monitored rail (3.3 V). Its reset logic asserts when any input falls below its threshold and holds RESET low for ≥140 ms after all inputs recover - with typical timeout of 200 ms and max 280 ms across temperature.

It features built-in 0.3% threshold hysteresis, 60 ppm/°C temperature coefficient, and glitch-immune input architecture validated for transients <1 µs at ≤100 mV overdrive. Unused inputs must be biased above their thresholds - not floated or grounded - using external resistors per Analog Devices' guidance.

FAQ

What voltage rails does the ADM6710LARJZ-REEL7 monitor?

The ADM6710LARJZ-REEL7 monitors four voltage rails: IN1 (adjustable via external resistor divider), IN2 = 3.3 V (factory-trimmed, ±5%), IN3 = 1.8 V (factory-trimmed, ±5%), and IN4 (adjustable). IN2 also powers the device internally, and RESET validity is maintained as long as IN1 or IN2 remains ≥1 V.

Does ADM6710LARJZ-REEL7 require an external pull-up resistor on the RESET pin?

No - ADM6710LARJZ-REEL7 includes a 10 µA internal pull-up to IN2, sufficient for most logic interfaces. An external pull-up is only needed when interfacing with a different logic supply (e.g., 5 V MCU while IN2 = 3.3 V), and even then, the internal circuitry prevents reverse current flow into IN2.

How is the adjustable threshold set on ADM6710LARJZ-REEL7 inputs IN1 and IN4?

Each adjustable input (IN1, IN4) references an internal 0.62 V ±1.5% precision bandgap. To monitor a higher voltage, use a resistor divider where V_TH = 0.62 × (1 + R1/R2). For example, to monitor 5 V, select R1/R2 ≈ 7.06. Unused adjustable inputs must be biased above their threshold - not left floating - using a 1 MΩ resistor to IN2.

What is the operating temperature range of ADM6710LARJZ-REEL7?

ADM6710LARJZ-REEL7 is fully specified from −40°C to +125°C, with performance validated across this range - including RESET timeout (140–280 ms), threshold accuracy, and input current. This makes it suitable for under-hood automotive, industrial control, and telecom base station applications.

Can ADM6710LARJZ-REEL7 replace older ADM6710 variants with different branding codes?

Yes - ADM6710LARJZ-REEL7 shares identical pinout, electrical behavior, and package (RJ-6 SOT-23) with other ADM6710xARJZ-REEL7 variants. The "L" denotes IN1/IN4 adjustable, IN2 = 3.3 V, IN3 = 1.8 V, and ±5% tolerance. Substituting other variants (e.g., "A", "D") changes threshold combinations or tolerances but retains mechanical and functional compatibility.
