Product details
Overview
ADM6710AARJZ-REEL7 from Analog Devices is a low-voltage, high-accuracy quad-supply supervisory IC that monitors four independent power rails: IN1 = 5 V (−10%), IN2 = 3.3 V, IN3 = 2.5 V, and IN4 = adjustable (0.62 V internal reference). It features 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. It is used in server power sequencing and microprocessor system reset management.
For engineers reviewing the ADM6710AARJZ-REEL7 datasheet, ADM6710AARJZ-REEL7 pinout, ADM6710AARJZ-REEL7 application, or ADM6710AARJZ-REEL7 equivalent, key selection criteria include factory-set threshold accuracy (±1.5% for adjustable input), guaranteed RESET validity down to IN1 or IN2 = 1 V, glitch immunity, and SOT-23-6 package compatibility with space-constrained embedded control designs.
Technical Context
The ADM6710AARJZ-REEL7 implements four independent voltage comparators with factory-trimmed thresholds for IN1 (5 V), IN2 (3.3 V), IN3 (2.5 V), and an adjustable IN4 referenced to a 0.62 V internal bandgap. Each comparator includes 0.3% threshold hysteresis to reject noise and transient glitches.
Its RESET output is open-drain, internally pulled up to IN2 (not VCC), remains valid as long as IN1 ≥ 1 V or IN2 ≥ 1 V, and asserts low when any monitored supply falls below its threshold. After all supplies recover, RESET stays low for 140–280 ms before deasserting - a fixed timeout generated by an on-chip RC timing circuit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Supplies | Four inputs: IN1 = 5 V (−10%), IN2 = 3.3 V, IN3 = 2.5 V, IN4 = adjustable via resistor divider (0.62 V ref) |
| Reset Timeout | 140–280 ms - ensures reliable processor reset hold time after power stabilization |
| 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 |
| Supply Validity Range | RESET remains functional while IN1 ≥ 1 V or IN2 ≥ 1 V - supports brown-out detection during deep undervoltage |
| Operating Temp | −40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Quiescent Current | 35 µA typical - enables use in always-on monitoring without significant battery drain |
| Threshold Accuracy | ±1.5% for adjustable input (IN4); ±2.5% max for factory-set thresholds - ensures precise power rail qualification |
Pinout & Package
ADM6710AARJZ-REEL7 is housed in a RoHS-compliant 6-lead SOT-23 (RJ-6) package, measuring 2.90 mm × 1.60 mm × 1.15 mm, with gull-wing leads and JEDEC MO-178-AB compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Monitored voltage input | Factory-set 5 V (−10%) threshold; must be connected to ≥5 V rail or disabled per spec |
| 2 - IN2 | Power supply & monitored input | Primary power source (3.3 V nominal) and monitored rail; internal pull-up target for RESET |
| 3 - IN3 | Monitored voltage input | Factory-set 2.5 V threshold; requires connection to 2.5 V supply or proper biasing if unused |
| 4 - IN4 | Adjustable monitored input | 0.62 V internal reference; supports custom thresholds (e.g., 1.2 V, 1.8 V) via external resistor divider |
| 5 - GND | Ground reference | Analog and digital ground return; must be low-impedance and tied to system common ground |
| 6 - RESET | Active-low open-drain output | Asserts low on fault; requires external pull-up only if interfacing to logic >3.3 V or needing faster rise time |
Key Features
| Feature | Design Value |
|---|---|
| Quad-supply monitoring | Simultaneously supervises 5 V, 3.3 V, 2.5 V, and one user-defined rail - reduces BOM count vs. discrete supervisors |
| Glitch-immune detection | Rejects transients <100 µs at ≥20 mV overdrive - prevents spurious resets in noisy power environments |
| Wide supply validity | RESET remains asserted/deasserted correctly even as IN1 or IN2 drops to 1 V - enables robust brown-out response |
| Low-power operation | 35 µA ICC - suitable for battery-backed systems and always-on monitoring without compromising runtime |
| High-temp reliability | Specified from −40°C to +125°C with 60 ppm/°C threshold drift - meets extended industrial and automotive requirements |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6816EUT+T | Triple-monitor (not quad); 1.6 V min supply; no adjustable input; 200 ms timeout | Lacks IN4 adjustability and 5 V monitoring - insufficient for 4-rail systems requiring flexible threshold assignment | Select only if design uses ≤3 rails and does not require 0.62 V-based monitoring |
| TPS3808G33DBVR | Single-channel 3.3 V supervisor; 200 ms timeout; 35 µA IQ; SOT-23-6 | No multi-rail capability - requires three separate ICs to match ADM6710AARJZ-REEL7's quad function | Choose only for cost-sensitive single-rail applications where board area is not constrained |
Compared with MAX6816EUT+T and TPS3808G33DBVR, the ADM6710AARJZ-REEL7 uniquely integrates four independently configured voltage monitors in one SOT-23-6 package, enabling compact, deterministic power sequencing without external dividers for three rails and full flexibility for the fourth - a capability unmatched by either alternative.

FAQ
What is the exact threshold voltage for each monitored input on the ADM6710AARJZ-REEL7?
The ADM6710AARJZ-REEL7 has factory-set thresholds: IN1 = 4.50 V to 4.75 V (5 V −10%), IN2 = 3.00 V to 3.15 V (3.3 V −5%), IN3 = 2.25 V to 2.38 V (2.5 V −10%), and IN4 = 0.611 V to 0.629 V (adjustable reference). These values are specified in Table 1 of the Rev. B datasheet and confirmed for the A-grade variant.
Can the ADM6710AARJZ-REEL7 monitor a 1.2 V supply, and how is it configured?
Yes - the ADM6710AARJZ-REEL7 can monitor a 1.2 V supply using IN4, which references an internal 0.62 V threshold. A resistor divider (e.g., R1 = 930 kΩ, R2 = 1 MΩ) scales the 1.2 V rail down to 0.62 V at IN4. The device's ±1.5% reference accuracy ensures the monitored threshold remains within ±18 mV of 1.2 V.
Does the ADM6710AARJZ-REEL7 require an external pull-up resistor on the RESET pin?
No - the ADM6710AARJZ-REEL7 includes a 10 µA internal pull-up to IN2, sufficient for most 3.3 V logic interfaces. An external pull-up is only needed when driving logic with higher voltage (e.g., 5 V) or when faster RESET rise time is required. The internal circuitry blocks reverse current flow into IN2.
What happens to the RESET output if IN2 drops below 1 V while IN1 remains above threshold?
If IN2 falls below 1 V, the ADM6710AARJZ-REEL7's RESET output becomes invalid - it may float or behave unpredictably - even if IN1 remains above its 4.5 V threshold. The datasheet explicitly states RESET validity requires IN1 ≥ 1 V *or* IN2 ≥ 1 V; both falling below 1 V disables guaranteed operation.
Is the ADM6710AARJZ-REEL7 pin-compatible with other variants in the ADM6710 family?
Yes - all ADM6710 variants, including ADM6710AARJZ-REEL7, use the same 6-lead SOT-23 (RJ-6) package and identical pinout (IN1, IN2, IN3, IN4, GND, RESET). However, internal threshold configurations differ; swapping variants without updating the BOM may cause incorrect supervision behavior.
