Product details
Overview
ADM1813-5ART-REEL7 from Analog Devices is a microprocessor reset circuit with open-drain output and manual push-button reset capability, designed for monitoring 5 V power supplies. It features a 4.62 V (typ) reset threshold, 150 ms (typ) reset timeout, 5.5 kΩ internal pull-up resistor, and operates across –40°C to +105°C. It ensures safe system initialization in embedded controllers and automotive ECUs.
For engineers reviewing the ADM1813-5ART-REEL7 datasheet, ADM1813-5ART-REEL7 pinout, ADM1813-5ART-REEL7 application, or ADM1813-5ART-REEL7 equivalent, key selection considerations include its open-drain RST output, push-button reset timing (1 µs detect → 150 ms active), 3-pin SOT-23 package, low 9–16 µA supply current, and compatibility with 5 V supply monitoring in space-constrained industrial systems.
Technical Context
The ADM1813-5ART-REEL7 implements a precision voltage comparator with built-in 150 ms delay timer and internal pull-up resistor (5.5 kΩ typ). Its open-drain output allows wired-OR configuration and direct interface with microprocessor reset inputs requiring active-low assertion.
It supports manual reset via external push-button connected between RST and GND, with sub-microsecond detection (1 µs minimum press) and guaranteed 100–250 ms reset pulse width after release. The device uses bandgap-referenced threshold detection with ±1.5% typical accuracy over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.62 V (typ); precise trip point for reliable 5 V supply monitoring with ±1.5% tolerance over temperature. |
| Reset Timeout | 150 ms (typ); ensures stable power-up before releasing reset, preventing premature CPU execution. |
| Supply Current | 9–16 µA at 5.5 V; ultra-low quiescent draw suitable for always-on monitoring in battery-backed systems. |
| Output Type | Open-drain RST; enables flexible logic-level translation and multi-device reset bus sharing. |
| Internal Pull-up | 5.5 kΩ (typ); eliminates need for external resistor when interfacing with standard CMOS reset inputs. |
| Operating Temp | –40°C to +105°C; qualified for under-hood automotive and industrial control environments. |
| Package | SOT-23 (RT-3); 3-pin, surface-mount footprint (2.9 × 1.3 mm) enabling high-density PCB layouts. |
Pinout & Package
ADM1813-5ART-REEL7 is housed in a 3-lead SOT-23 (RT-3) package per JEDEC TO-236AB, with 1.9–2.1 mm body width, 1.2–1.4 mm height, and 0.95 mm pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RST) | Open-drain reset output | Active-low signal asserted when VCC falls below 4.62 V or push-button is pressed; requires external pull-up if not using internal 5.5 kΩ resistor. |
| 2 (VCC) | Monitored supply input | Primary power rail being supervised; device draws current only from this pin and regulates internal bias from it. |
| 3 (GND) | Ground reference | Common return path for all internal circuitry and reset output sink current; must be low-impedance connection. |
Key Features
| Feature | Design Value |
|---|---|
| Push-button reset support | Enables field-serviceable hardware reset without software intervention; detects ≥1 µs button press and guarantees 150 ms reset hold time. |
| Integrated pull-up resistor | 5.5 kΩ typical value eliminates external component count and simplifies interface to standard microprocessor reset pins. |
| Wide temperature operation | –40°C to +105°C rating ensures functional reliability in automotive engine control units and industrial PLCs. |
| Low-power supervision | 9 µA min supply current at 5.5 V enables continuous monitoring in energy-sensitive applications without compromising battery life. |
| Precision voltage threshold | 4.62 V ±1.5% over full temperature range provides deterministic reset behavior without calibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor with push-button reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.63 V threshold, 140 ms reset timeout, no push-button support, 3-pin SOT-23 | Lacks manual reset functionality; requires external switch circuitry for field reset | Select when push-button reset is unnecessary and tighter threshold tolerance (±1.0%) is prioritized. |
| TPS3808G01DBVR | 4.63 V threshold, adjustable reset delay (1–10 s), push-button compatible via external capacitor, 5-pin SOT-23 | Requires external RC network for push-button timing; larger footprint and higher cost | Choose when programmable delay or enhanced ESD protection (4 kV HBM) is required for harsh environments. |
Compared with MAX809SEUR+T and TPS3808G01DBVR, the ADM1813-5ART-REEL7 uniquely integrates push-button detection and internal pull-up in a minimal 3-pin SOT-23, reducing component count and layout complexity for cost-sensitive 5 V reset applications where fixed 150 ms timing is acceptable.

FAQ
What is the reset threshold voltage of the ADM1813-5ART-REEL7?
The ADM1813-5ART-REEL7 has a nominal reset threshold of 4.62 V (typical), with a specified range of 4.50 V to 4.75 V over temperature and process variation. This threshold is factory-trimmed and referenced to an internal bandgap, ensuring consistent 5 V supply monitoring without external calibration. The ADM1813-5ART-REEL7 maintains this accuracy across its full operating temperature range of –40°C to +105°C.
Does the ADM1813-5ART-REEL7 support manual reset via push-button?
Yes, the ADM1813-5ART-REEL7 explicitly supports manual reset through an external push-button connected between the RST pin and GND. It detects button presses as short as 1 µs and asserts a 150 ms (typical) reset pulse upon release. This feature is confirmed in the Functional Block Diagram, Pin Function Descriptions, and ADM1813/ADM1818 dedicated section of the datasheet. The ADM1813-5ART-REEL7 implements this without requiring additional components.
What package type does the ADM1813-5ART-REEL7 use?
The ADM1813-5ART-REEL7 uses the RT-3 (SOT-23) package: a 3-lead, surface-mount small-outline transistor package compliant with JEDEC TO-236AB. Its dimensions are 2.90 mm × 1.30 mm × 1.12 mm (L × W × H), with 0.95 mm pin pitch. This package is explicitly listed in the Ordering Guide and Outline Dimensions section for the ADM1813-5ART-REEL7 model.
What is the supply current consumption of the ADM1813-5ART-REEL7?
The ADM1813-5ART-REEL7 draws 9 µA (minimum) to 16 µA (maximum) supply current at VCC = 5.5 V and ambient temperature from 0°C to +105°C. At 3.6 V, consumption drops to 4–10 µA. These values are measured under no-load conditions with VCC above the reset threshold and are specified in the SUPPLY Current row of the Electrical Specifications table. Low current enables continuous monitoring in power-sensitive designs.
Is the ADM1813-5ART-REEL7 output push-pull or open-drain?
The ADM1813-5ART-REEL7 features an open-drain RST output, as confirmed in the FEATURES section ("Open-Drain Output Choices (ADM1811, ADM1813, ADM1816, and ADM1818)") and the Functional Block Diagram. This allows wired-OR reset bus configurations and level-shifting flexibility. Unlike push-pull variants (e.g., ADM1810/ADM1812), the ADM1813-5ART-REEL7 requires either its internal 5.5 kΩ pull-up or an external resistor to establish a defined high state.
