Analog Devices Inc. ADM6710DARJZ-REEL7

Overview

ADM6710DARJZ-REEL7 from Analog Devices is a low-voltage, high-accuracy quad-supply supervisory IC that monitors IN1 = 5 V (±5%), IN2 = 3.3 V, IN3 = 1.8 V, and IN4 as adjustable (0.62 V reference), with 200 ms reset timeout, open-drain active-low RESET output, and operation from −40°C to +125°C in a 6-lead SOT-23 package - used for reliable power-on reset and brownout detection in embedded microprocessor systems.

For engineers reviewing the ADM6710DARJZ-REEL7 datasheet, ADM6710DARJZ-REEL7 pinout, ADM6710DARJZ-REEL7 application, or ADM6710DARJZ-REEL7 equivalent, key selection criteria include factory-set threshold accuracy (±5% on 5 V input), guaranteed RESET validity down to IN1 or IN2 = 1 V, 35 µA supply current, glitch-immune monitoring, and SOT-23 footprint compatibility across the ADM6710 family.

Technical Context

The ADM6710DARJZ-REEL7 implements four independent voltage comparators tied to a shared 200 ms timeout timer and open-drain RESET driver. Its internal 0.62 V reference enables precise resistor-divider-based adjustment for IN4, while IN1–IN3 are factory-trimmed for 5 V (±5%), 3.3 V, and 1.8 V nominal supplies respectively.

Power is derived from IN2 (3.3 V), eliminating need for separate VCC; RESET remains valid as long as IN1 ≥ 1 V or IN2 ≥ 1 V. Input hysteresis is 0.3% of threshold voltage, and the device rejects transients ≤ 100 µs at typical overdrive levels - critical for noisy industrial power rails.

FAQ

What voltage rails does the ADM6710DARJZ-REEL7 monitor?

The ADM6710DARJZ-REEL7 monitors four voltage rails: IN1 is factory-set to 5 V (±5%), IN2 to 3.3 V, IN3 to 1.8 V, and IN4 is adjustable using the internal 0.62 V reference. This configuration is explicitly defined in the Ordering Guide for ADM6710DARJZ-REEL7 and confirmed in Table 4 and Figure 2 of the Rev. B datasheet.

Does ADM6710DARJZ-REEL7 require an external pull-up resistor on the RESET pin?

No - ADM6710DARJZ-REEL7 includes a 10 µA internal pull-up to IN2, making an external pull-up unnecessary in most 3.3 V logic interfaces. The datasheet states RESET is "open-drain with a weak internal pull-up to the monitored IN2 supply" and notes that "many applications … do not require an external pull-up resistor."

What is the operating temperature range of ADM6710DARJZ-REEL7?

The ADM6710DARJZ-REEL7 is fully specified from −40°C to +125°C, as stated in the General Description, Absolute Maximum Ratings (Table 2), and Ordering Guide. This extended range is validated across all electrical parameters in the Specifications table (Page 3) and supported by performance curves (e.g., Figure 9 for timeout vs. temperature).

How does the reset timeout behave after all monitored voltages recover?

After all monitored inputs rise above their respective thresholds, the ADM6710DARJZ-REEL7 holds RESET low for a guaranteed 140 ms to 280 ms period, with 200 ms typical. This timeout is generated by an internal timer and is independent of input slew rate - ensuring consistent deassertion timing regardless of how quickly supplies recover.

Can unused inputs be left floating on ADM6710DARJZ-REEL7?

No - unused inputs must not float or be grounded. Per the General Description and Theory of Operation sections, unused INx pins must be connected to a supply voltage greater than their specified threshold (e.g., tie IN4 to 3.3 V if unused), or, for adjustable inputs, use a 1 MΩ series resistor to IN2 to limit bias current and prevent false triggering.
