Product details
Overview
ADM6710IARJZ-REEL7 from Analog Devices is a high-accuracy quad-voltage microprocessor supervisory circuit in a 6-lead SOT-23 package, monitoring four supply rails with factory-set and adjustable thresholds (including 3.3 V on IN2, 2.5 V on IN3, and adjustable 0.62 V references on IN1 and IN4). It delivers 200 ms typical reset timeout, open-drain active-low RESET output with 10 µA internal pull-up to IN2, and operates across −40°C to +125°C for industrial-grade system reliability.
For engineers reviewing the ADM6710IARJZ-REEL7 datasheet, ADM6710IARJZ-REEL7 pinout, ADM6710IARJZ-REEL7 application, or ADM6710IARJZ-REEL7 equivalent, key selection criteria include its triple-adjustable-input configuration (IN1/IN3/IN4), guaranteed RESET validity down to IN1 or IN2 = 1 V, low 35 µA quiescent current, and immunity to power supply glitches in telecom and server power sequencing.
Technical Context
The ADM6710IARJZ-REEL7 implements four independent voltage comparators with internal 0.62 V reference and resistor-divider-compatible inputs. Its architecture supports mixed-supply monitoring: IN2 (3.3 V) powers the device and serves as monitored rail; IN3 is factory-trimmed to 2.5 V ±5%; IN1 and IN4 are adjustable via external dividers referencing the 0.62 V threshold (±1.5% accuracy).
Reset assertion occurs when any input falls below its threshold; deassertion requires all inputs to exceed thresholds plus a fixed 200 ms timeout. The open-drain RESET output remains valid while IN1 or IN2 ≥ 1 V, enabling robust operation during brown-out conditions without requiring auxiliary biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Monitoring Inputs | Four: IN1 (adjustable), IN2 (3.3 V monitored & power source), IN3 (2.5 V factory-set), IN4 (adjustable) |
| Threshold Accuracy | ±1.5% for adjustable inputs (0.62 V reference); ±5% for IN3 (2.5 V nominal) |
| Reset Timeout | 200 ms typical - ensures stable processor boot after full rail recovery |
| Quiescent Current | 35 µA - enables always-on supervision in low-power embedded systems |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial control, and telecom base station use |
| RESET Output Type | Open-drain with 10 µA internal pull-up to IN2 - eliminates need for external pull-up in many 3.3 V logic interfaces |
| Input Glitch Immunity | Valid against transients <100 µs at ≤50 mV overdrive - prevents false resets in noisy power environments |
Pinout & Package
ADM6710IARJZ-REEL7 is housed in a RoHS-compliant 6-lead SOT-23 (RJ-6) package, 2.9 mm × 1.6 mm × 1.15 mm, JEDEC MO-178-AB compliant, with gull-wing leads and pin 1 marked.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable monitor input | Accepts external resistor divider to set threshold down to 0.62 V; must be tied > threshold if unused |
| 2 - IN2 | Primary power supply & monitored rail | 3.3 V nominal input; powers internal circuitry and asserts RESET if <3.15 V (−5%) |
| 3 - IN3 | Factory-set monitor input | 2.5 V ±5% threshold; monitors secondary rail without external components |
| 4 - IN4 | Adjustable monitor input | Second adjustable input (0.62 V reference); supports third independent rail monitoring |
| 5 - GND | Analog ground reference | Common return for all comparators and RESET driver; requires low-impedance connection |
| 6 - RESET | Active-low open-drain output | Drives low when any input fails; pulls high via 10 µA internal current to IN2; compatible with 1.8–5.5 V logic |
Key Features
| Feature | Design Value |
|---|---|
| Quad-rail supervision | Simultaneously monitors IN1 (adj), IN2 (3.3 V), IN3 (2.5 V), IN4 (adj) - reduces BOM count vs. discrete supervisors |
| Adjustable threshold precision | 0.62 V internal reference with ±1.5% accuracy enables reliable sub-1 V rail monitoring (e.g., core voltages) |
| Glitch-immune detection | Rejects transients <100 µs duration - eliminates spurious resets during switching noise or load dumps |
| Extended temperature operation | Full functionality from −40°C to +125°C - supports deployment in uncooled industrial enclosures and automotive ECUs |
| Low-power active supervision | 35 µA ICC enables continuous monitoring in battery-backed or energy-harvesting systems without compromising runtime |
Applications

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 (not quad); fixed 3.0 V/3.3 V/5.0 V thresholds only; no adjustable inputs | Lacks support for sub-2.5 V rails like FPGA cores or DDR memory; requires external resistors for nonstandard voltages | Select when only three standard rails require supervision and cost-per-channel is prioritized over flexibility |
| TPS3808G33DBVR | Single-supply supervisor (3.3 V only); no multi-rail capability; includes manual reset input | Cannot replace quad monitoring function without stacking multiple devices; adds PCB area and routing complexity | Choose for simple 3.3 V-only systems where manual reset is mandatory and quad supervision is unnecessary |
Compared with MAX6816EUT+T and TPS3808G33DBVR, the ADM6710IARJZ-REEL7 uniquely combines quad-rail coverage, two adjustable thresholds, and industrial temperature range in one SOT-23 package-enabling single-chip supervision of mixed-voltage SoC platforms without layout compromise.

FAQ
What voltage rails does the ADM6710IARJZ-REEL7 monitor?
The ADM6710IARJZ-REEL7 monitors four voltage rails: IN1 and IN4 are adjustable inputs referenced to an internal 0.62 V threshold (supporting custom rail voltages via resistor dividers), IN2 is factory-configured for 3.3 V monitoring and also supplies internal circuitry, and IN3 is factory-trimmed to 2.5 V ±5%. This configuration is explicitly defined in the Ordering Guide for ADM6710IARJZ-REEL7.
How does the RESET output behave during brown-out conditions?
The ADM6710IARJZ-REEL7 RESET output remains valid and functional as long as IN1 or IN2 exceeds 1 V - meaning it continues asserting reset even during deep brown-outs where other supervisors may lose regulation. Its open-drain structure with 10 µA internal pull-up to IN2 ensures compatibility with 1.8–5.5 V logic families without external components.
Can unused inputs be left floating on the ADM6710IARJZ-REEL7?
No. Unused inputs on the ADM6710IARJZ-REEL7 must not float or be grounded. Per the datasheet, they must be connected to a supply voltage greater than their specified threshold (e.g., tie unused IN1 to 3.3 V). For adjustable inputs, a 1 MΩ series resistor to IN2 is recommended to limit bias current while maintaining valid logic state.
What is the reset timeout period for the ADM6710IARJZ-REEL7?
The ADM6710IARJZ-REEL7 provides a typical reset timeout period of 200 ms after all monitored voltages rise above their respective thresholds. The datasheet specifies this as 140 ms (min) to 280 ms (max) across temperature, ensuring sufficient hold time for microprocessors and FPGAs to complete internal initialization before release.
Does the ADM6710IARJZ-REEL7 support manual reset functionality?
The ADM6710IARJZ-REEL7 does not integrate a dedicated manual reset pin. However, manual reset can be implemented externally by shorting an adjustable input (e.g., IN4) to ground through a switch - triggering reset assertion per the "Addition of Manual Reset" circuit in Figure 15 of the datasheet. This method requires ≥140 ms switch-open time for proper deassertion.
