Product details
Overview
ADM6710EARJZ-REEL7 from Analog Devices is a low-voltage, high-accuracy quad-supply supervisory IC that monitors four independent power rails-IN1 (adjustable), IN2 (3.3 V), IN3 (2.5 V), and IN4 (1.8 V)-with factory-trimmed thresholds and 10% tolerance. It delivers a single active-low open-drain RESET output with 200 ms typical timeout, operates from −40°C to +125°C, and draws only 35 μA supply current. It is used in microprocessor-based systems requiring reliable power-on reset and brownout detection across multiple voltage domains.
For engineers reviewing the ADM6710EARJZ-REEL7 datasheet, ADM6710EARJZ-REEL7 pinout, ADM6710EARJZ-REEL7 application, or ADM6710EARJZ-REEL7 equivalent, key selection criteria include its 3.3 V/2.5 V/1.8 V fixed monitoring channels plus one adjustable input (0.62 V reference), guaranteed RESET validity down to IN1 or IN2 = 1 V, and SOT-23-6 packaging for space-constrained embedded designs.
Technical Context
The ADM6710EARJZ-REEL7 implements four independent voltage comparators with internal 0.62 V reference and resistor-divider-compatible inputs. IN2 serves as both monitored rail and power supply (no separate VCC), enabling true 4-rail supervision without auxiliary biasing. Its UVLO architecture includes 0.3% threshold hysteresis and glitch immunity up to 100 µs at 50 mV overdrive.
RESET assertion occurs when any input falls below its specified threshold; deassertion requires all inputs to exceed thresholds and a fixed 140–280 ms timeout. The open-drain output features a 10 µA internal pull-up to IN2 and remains functional down to IN1 or IN2 = 1 V-critical for low-voltage system sequencing and fail-safe operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | IN1: adjustable (via resistor divider, ref = 0.62 V); IN2 = 3.3 V; IN3 = 2.5 V; IN4 = 1.8 V - supports mixed-voltage SoC/FPGA power domains |
| Threshold Accuracy | ±10% for fixed rails; ±1.5% for adjustable input - enables precise brownout detection without external trimming |
| Reset Timeout | 140–280 ms (typ. 200 ms) - ensures stable CPU initialization after power stabilization |
| Supply Current | 35 μA (typ.) - minimizes standby power impact in battery-backed or always-on systems |
| Operating Temp | −40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| RESET Output | Open-drain, active-low, 10 μA internal pull-up to IN2 - eliminates need for external pull-up in many 3.3 V logic interfaces |
| Input Validity | RESET remains valid while IN1 ≥ 1 V or IN2 ≥ 1 V - supports graceful shutdown during deep brownout |
Pinout & Package
ADM6710EARJZ-REEL7 is housed in a RoHS-compliant 6-lead SOT-23 package (JEDEC MO-178-AB, RJ-6), measuring 2.90 mm × 1.60 mm × 1.15 mm, suitable for automated high-density PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable monitor input | Accepts resistor-divided voltage; internally compared to 0.62 V reference - enables custom threshold setting for non-standard rails |
| 2 - IN2 | Monitored 3.3 V supply & power source | Supplies device core and hosts internal pull-up for RESET; must be ≥1 V for RESET validity |
| 3 - IN3 | Monitored 2.5 V supply | Factory-trimmed comparator input; no external components required for 2.5 V rail supervision |
| 4 - IN4 | Monitored 1.8 V supply | Factory-trimmed comparator input; supports low-voltage I/O or core domain monitoring |
| 5 - GND | Analog ground reference | Common return for all comparators and RESET driver; must be low-impedance for noise immunity |
| 6 - RESET | Active-low open-drain output | Asserts low on any undervoltage event; requires external pull-up only if interfacing to >3.3 V logic |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent voltage monitoring | Simultaneously supervises 3.3 V, 2.5 V, 1.8 V, and one user-defined rail - eliminates need for multiple discrete supervisors |
| 0.62 V precision internal reference | Enables accurate adjustable thresholds via simple resistor dividers - avoids external reference ICs and calibration |
| 10 µA internal RESET pull-up | Reduces BOM count and board area by removing external pull-up in 3.3 V systems - simplifies interface to microcontroller reset pins |
| 1 V minimum input validity | Guarantees RESET state integrity even during severe brownout - prevents spurious resets during power collapse |
| 0.3% threshold hysteresis | Rejects noise-induced false triggers without sacrificing accuracy - improves reliability in electrically noisy industrial environments |

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); 1.2 V, 3.3 V, 5 V thresholds only; no adjustable input; 100 ms timeout | Lacks IN1 adjustability and 1.8 V/2.5 V support - unsuitable for mixed-voltage FPGA or SoC platforms | Select only for simpler 3-rail systems where adjustable threshold and 1.8 V monitoring are unnecessary |

FAQ
What voltage rails does the ADM6710EARJZ-REEL7 monitor?
The ADM6710EARJZ-REEL7 monitors four distinct voltage rails: IN1 is adjustable (using a resistor divider referenced to its internal 0.62 V threshold), IN2 is factory-set to 3.3 V, IN3 to 2.5 V, and IN4 to 1.8 V. All thresholds are specified with ±10% tolerance, and the device asserts RESET if any monitored rail drops below its respective threshold. This configuration is explicitly defined in the Ordering Guide for the ADM6710EARJZ-REEL7 variant.
Does the ADM6710EARJZ-REEL7 require an external power supply pin?
No-the ADM6710EARJZ-REEL7 derives operating power directly from the IN2 input (3.3 V rail), eliminating the need for a dedicated VCC pin. This architecture simplifies power routing and ensures the supervisor remains active as long as IN2 is present above 1 V. Unlike the ADM6710Q variant, which uses a separate VCC pin, the ADM6710EARJZ-REEL7 integrates power and monitoring on IN2, as confirmed in the Pin Function Descriptions and General Description sections of the datasheet.
What is the RESET timeout duration for the ADM6710EARJZ-REEL7?
The ADM6710EARJZ-REEL7 provides a guaranteed RESET timeout period between 140 ms and 280 ms, with a typical value of 200 ms. This timeout begins after all monitored inputs rise above their respective thresholds and ensures the microprocessor receives a clean, extended reset pulse for reliable initialization. The specification is validated across −40°C to +125°C and appears in Table 1 under "RESET TIMEOUT PERIOD (tRP)" for all ADM6710 variants including ADM6710EARJZ-REEL7.
Can unused inputs on the ADM6710EARJZ-REEL7 be left floating?
No-unused inputs on the ADM6710EARJZ-REEL7 must never be left floating or grounded. Per the Input Configuration section, they must be tied to a supply voltage exceeding their specified threshold (e.g., connect unused IN3 to ≥2.7 V). For adjustable inputs like IN1, a 1 MΩ series resistor to IN2 is recommended to limit bias current. Floating inputs risk false RESET assertions due to noise coupling, and grounding violates absolute maximum ratings, potentially damaging the internal comparators.
Is the ADM6710EARJZ-REEL7 compatible with 1.0 V logic-level systems?
The ADM6710EARJZ-REEL7 RESET output remains valid down to IN1 or IN2 = 1.0 V, but it does not operate *from* a 1.0 V supply. Its minimum functional IN2 voltage is 1.0 V per Absolute Maximum Ratings, yet proper supervision requires IN2 ≥ 3.3 V (its nominal threshold). The 1.0 V validity window applies only during brownout recovery-not steady-state operation. Therefore, the ADM6710EARJZ-REEL7 is not intended for 1.0 V system-level logic compatibility; it is designed for 1.8 V/2.5 V/3.3 V multi-rail supervision with robust low-voltage fault handling.
