Product details
Overview
ADM6710FARJZ-REEL7 from Analog Devices is a high-accuracy quad-voltage microprocessor supervisory circuit in a 6-lead SOT-23 package, monitoring adjustable (IN1), 3.3 V (IN2), 2.5 V (IN3), and 1.8 V (IN4) supplies with ±5% threshold tolerance, 200 ms reset timeout, and operation from −40°C to +125°C - used for reliable power-on reset and brownout detection in embedded computing systems.
For engineers reviewing the ADM6710FARJZ-REEL7 datasheet, ADM6710FARJZ-REEL7 pinout, ADM6710FARJZ-REEL7 application, or ADM6710FARJZ-REEL7 equivalent, key selection criteria include its factory-configured 5% threshold accuracy on IN3 (2.5 V) and IN4 (1.8 V), open-drain RESET output with internal 10 µA pull-up to IN2, and guaranteed validity down to IN1 or IN2 = 1 V.
Technical Context
The ADM6710FARJZ-REEL7 implements four independent voltage comparators with internal 0.62 V reference, where IN1 is fully adjustable via external resistor divider while IN2, IN3, and IN4 are factory-set to 3.3 V, 2.5 V, and 1.8 V respectively. Its UVLO detection logic asserts active-low RESET when any monitored supply falls below its threshold, with built-in 0.3% hysteresis per input to suppress noise-induced false triggers.
RESET remains asserted for a fixed 200 ms (typical) timeout after all inputs recover above threshold; the open-drain output is pulled up internally to IN2 (not VCC), enabling direct interfacing with logic operating at different supply voltages without external pull-up - critical for mixed-rail systems requiring glitch-immune supervision.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6816EUT+T | Triple-monitor only (no IN1 adjustability); 200 ms timeout; ±2.5% threshold accuracy on fixed rails | Lacks adjustable IN1 input; suitable only for fixed-rail systems without custom voltage supervision | Select when exact 1.8/2.5/3.3 V monitoring suffices and design does not require IN1 flexibility |
| TPS3808G33DBVR | Single 3.3 V monitor with manual reset; no multi-rail capability; 200 ms timeout; ±0.5% accuracy | Cannot supervise 1.8 V or 2.5 V rails simultaneously; requires three separate ICs for full ADM6710FARJZ-REEL7 functionality | Choose only for simplified 3.3 V-only systems where cost-per-rail outweighs integration benefits |

FAQ
What voltage rails does the ADM6710FARJZ-REEL7 monitor?
The ADM6710FARJZ-REEL7 monitors four voltage rails: IN1 is adjustable (via external resistor divider, referenced to 0.62 V internal threshold), IN2 is factory-set to 3.3 V, IN3 to 2.5 V, and IN4 to 1.8 V - all with ±5% threshold tolerance. This configuration enables supervision of mixed-voltage SoC power domains in a single IC.
Does the ADM6710FARJZ-REEL7 require an external pull-up resistor on the RESET pin?
No, the ADM6710FARJZ-REEL7 features an internal 10 µA pull-up to IN2, eliminating the need for an external pull-up in most applications. An external pull-up may be added only if interfacing with logic operating above IN2 voltage (e.g., 5 V logic driven by 3.3 V IN2), but the internal circuitry prevents reverse current flow into IN2.
What is the minimum operating voltage for the ADM6710FARJZ-REEL7 to maintain valid RESET output?
The ADM6710FARJZ-REEL7 guarantees valid RESET output as long as either IN1 or IN2 remains ≥ 1 V. This 1 V lower limit extends supervision capability beyond typical 1.2 V cutoffs, allowing reliable reset assertion during deep brownout conditions common in automotive and industrial power systems.
How does the ADM6710FARJZ-REEL7 handle short power supply transients?
The ADM6710FARJZ-REEL7 incorporates built-in 0.3% hysteresis per input and is designed to reject transients ≤ 100 µs at typical overdrive levels, as verified in Figure 7 of the datasheet. Adding a 0.1 µF capacitor from IN2 to GND further enhances immunity to high-frequency noise and supply glitches.
Can unused inputs on the ADM6710FARJZ-REEL7 be left floating?
No - unused inputs on the ADM6710FARJZ-REEL7 must never float or be grounded. They must be tied to a supply voltage exceeding their specified threshold (e.g., connect unused IN1 to IN2 via a 1 MΩ resistor). Floating inputs cause unpredictable comparator behavior and potential false reset assertion.
