Product details
Overview
ADM6710NARJZ-REEL7 from Analog Devices is a low-voltage, high-accuracy quad-supply supervisory IC that monitors up to four system power rails - specifically configured for IN1 = adjustable (0.62 V reference), IN2 = 3.0 V, IN3 = 2.5 V, and IN4 = adjustable - with ±5% threshold tolerance, 200 ms typical reset timeout, and operation across −40°C to +125°C. It delivers reliable reset assertion during undervoltage events in microprocessor-based industrial control systems.
For engineers reviewing the ADM6710NARJZ-REEL7 datasheet, ADM6710NARJZ-REEL7 pinout, ADM6710NARJZ-REEL7 application, or ADM6710NARJZ-REEL7 equivalent, this device supports precise multi-rail monitoring in space-constrained embedded systems where supply sequencing, glitch immunity, and extended temperature stability are critical selection criteria.
Technical Context
The ADM6710NARJZ-REEL7 uses factory-trimmed comparators with internal 0.62 V reference to set adjustable thresholds via external resistor dividers, while fixed thresholds for IN2 and IN3 are preconfigured to 3.0 V and 2.5 V respectively. Its UVLO detection circuitry incorporates 0.3% hysteresis to suppress noise-induced false resets.
Power is derived from IN2 (3.0 V), eliminating need for separate bias supply; RESET output is open-drain with 10 µA internal pull-up to IN2 and remains valid down to IN1 or IN2 ≥ 1 V. The device asserts active-low RESET when any monitored input falls below its threshold and holds it for 140–280 ms after all inputs recover.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Inputs | Four: IN1 (adjustable), IN2 (3.0 V fixed), IN3 (2.5 V fixed), IN4 (adjustable) - enables flexible multi-rail supervision without external references. |
| Threshold Accuracy | ±5% for fixed thresholds (IN2/IN3); 1.5% for adjustable inputs (0.611–0.629 V) - ensures tight margin control for low-voltage logic domains. |
| Reset Timeout | 140–280 ms (typ. 200 ms) - provides sufficient hold time for CPU initialization and memory stabilization after power recovery. |
| Supply Range | IN2 = 1.2–5.5 V (−40°C to +125°C) - supports direct monitoring of 3.0 V rail while maintaining functionality down to 1.2 V under extreme cold. |
| Quiescent Current | 35 µA typical - minimizes standby power impact in battery-backed or energy-sensitive applications. |
| Operating Temp | −40°C to +125°C - qualified for under-hood automotive, industrial PLC, and telecom infrastructure environments. |
| Output Type | Open-drain RESET with 10 µA internal pull-up to IN2 - simplifies interface to diverse logic families without external pull-up in many cases. |
Pinout & Package
ADM6710NARJZ-REEL7 is housed in a RoHS-compliant 6-lead SOT-23 (RJ-6) package, measuring 2.90 mm × 1.60 mm × 1.15 mm, optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable voltage monitor input | Accepts externally divided voltage; threshold set by ratio to 0.62 V internal reference - used here for first adjustable rail. |
| 2 - IN2 | 3.0 V fixed-threshold monitor & power supply | Primary power source for IC and monitored 3.0 V rail; RESET validity sustained down to IN2 = 1.2 V at −40°C. |
| 3 - IN3 | 2.5 V fixed-threshold monitor input | Dedicated comparator for 2.5 V domain (e.g., I/O supply or analog subsystem) with ±5% accuracy over full temperature range. |
| 4 - IN4 | Adjustable voltage monitor input | Second adjustable input; identical architecture to IN1 - enables dual low-voltage core monitoring (e.g., 1.2 V CPU + 1.8 V GPU). |
| 5 - GND | Analog and digital ground reference | Single ground connection for all comparators and RESET driver; requires low-impedance layout to maintain noise immunity. |
| 6 - RESET | Active-low open-drain reset output | Drives microprocessor /CPLD reset pin; internal 10 µA pull-up avoids external component in 3.0 V systems; sinks ≥2 mA at 0.4 V. |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent voltage monitoring | Simultaneously supervises 3.0 V, 2.5 V, and two user-defined rails - eliminates need for multiple discrete supervisors in multi-supply SoC designs. |
| Factory-trimmed fixed thresholds | IN2 and IN3 thresholds laser-trimmed to ±5% at 3.0 V and 2.5 V - removes calibration overhead and improves BOM consistency. |
| 0.62 V precision internal reference | 1.5% accuracy over −40°C to +125°C - enables stable sub-1 V core voltage monitoring using simple resistor dividers. |
| Glitch-immune UVLO detection | Rejects transients <100 µs (per Figure 7) - prevents spurious resets during switching noise or load-dump events in industrial power supplies. |
| Extended temperature operation | Full parametric performance guaranteed from −40°C to +125°C - suitable for deployment in uncooled enclosures or engine-control modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326US31D3+T | Triple-monitor (3.08 V, 3.08 V, 3.08 V), no adjustable inputs; 140 ms timeout; SOT-23-6 | Limited to identical triple-rail monitoring; lacks dual adjustable capability required for heterogeneous supply systems. | Select when only three identical 3.0 V rails need supervision and cost sensitivity outweighs flexibility needs. |
| TPS3808G33DBVR | Single 3.3 V supervisor; 200 ms timeout; 35 µA IQ; SOT-23-6 | Monitors only one rail; requires three devices plus external logic to replicate ADM6710NARJZ-REEL7's quad functionality. | Choose only for single-rail applications where footprint and BOM count are secondary to procurement simplicity. |
Compared with MAX6326US31D3+T and TPS3808G33DBVR, the ADM6710NARJZ-REEL7 uniquely integrates two adjustable thresholds with two fixed ones in one SOT-23-6 package, enabling true heterogeneous multi-rail supervision without external components or layout complexity.

FAQ
What voltage rails does the ADM6710NARJZ-REEL7 monitor?
The ADM6710NARJZ-REEL7 monitors four inputs: IN1 and IN4 are adjustable (based on 0.62 V internal reference), IN2 is factory-set to 3.0 V, and IN3 is factory-set to 2.5 V. All thresholds are specified with ±5% tolerance over −40°C to +125°C, and the device derives power from IN2, making it self-sufficient in 3.0 V systems.
Does the ADM6710NARJZ-REEL7 require an external pull-up resistor on the RESET pin?
No - the ADM6710NARJZ-REEL7 includes a 10 µA internal pull-up to IN2, sufficient for most 3.0 V logic interfaces. An external pull-up is only needed if driving a higher-voltage domain (e.g., 5 V), and even then, internal circuitry prevents reverse current flow into IN2, preserving supply integrity.
How does the ADM6710NARJZ-REEL7 handle short power supply glitches?
The ADM6710NARJZ-REEL7 rejects transients shorter than ~100 µs (per Figure 7 in the datasheet), thanks to internal filtering and 0.3% threshold hysteresis. This immunity prevents false resets during switching regulator noise or brief line disturbances without requiring external capacitors on monitored inputs.
Can unused inputs on the ADM6710NARJZ-REEL7 be left floating?
No - unused inputs must not float or be grounded. For adjustable inputs (IN1 or IN4), connect through a 1 MΩ series resistor to IN2; for fixed inputs, tie to a supply > threshold (e.g., 3.3 V for IN3). Floating inputs risk erratic reset behavior due to leakage-induced false trips.
What is the minimum valid voltage on IN2 for the ADM6710NARJZ-REEL7 to operate?
The ADM6710NARJZ-REEL7 guarantees correct RESET state down to IN2 = 1.2 V at −40°C and 1.0 V at 0°C to +125°C. Below these levels, the internal circuitry may not sustain comparator bias or pull-up strength, so system design must ensure IN2 remains ≥1.2 V across the full rated temperature range.
