Product details
Overview
ADM1813-10ART-RL7 from Analog Devices is a 3-pin SOT-23 open-drain microprocessor reset circuit with internal pull-up resistor, 4.35 V typical reset threshold, 150 ms reset timeout, and push-button reset capability. It monitors 5 V power supplies in embedded controllers and industrial microprocessor systems requiring reliable power-on initialization.
For engineers reviewing the ADM1813-10ART-RL7 datasheet, ADM1813-10ART-RL7 pinout, ADM1813-10ART-RL7 application, or ADM1813-10ART-RL7 equivalent, key selection criteria include reset threshold tolerance (±0.14 V), operating temperature range (−40°C to +105°C), supply current (≤10 µA at 3.6 V), and compatibility with manual reset switches in space-constrained designs.
Technical Context
The ADM1813-10ART-RL7 implements a precision voltage comparator with hysteresis and a fixed 150 ms power-up delay timer. Its internal 5.5 kΩ pull-up resistor enables direct connection to standard CMOS reset inputs without external components.
It supports both automatic reset on VCC undervoltage and manual reset via external push-button tied between RST and GND - triggering a guaranteed 150 ms low pulse after button release. The device operates across the full industrial temperature range with no external timing capacitors required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.35 V typical (min 4.25 V, max 4.49 V); ensures reliable detection of 5 V supply collapse before system instability. |
| Reset Timeout | 150 ms typical (100–250 ms range); provides sufficient time for power rail stabilization before releasing processor reset. |
| Supply Current | 10 µA max at 3.6 V; enables ultra-low-power operation in battery-backed or energy-sensitive applications. |
| Output Type | Open-drain with internal 5.5 kΩ pull-up; simplifies interface to diverse logic families and eliminates need for external pull-up resistor. |
| Push-Button Response | 1 µs detect latency + 150 ms asserted reset; guarantees clean, debounced manual reset independent of switch bounce. |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood environments without derating. |
| Package | SOT-23 (RT-3); 3-pin surface-mount footprint compatible with high-density PCB layouts and automated assembly. |
Pinout & Package
ADM1813-10ART-RL7 is housed in a 3-lead SOT-23 (RT-3) package with JEDEC TO-236-AB compliance. Pin 1 is RST (active-low open-drain output), Pin 2 is VCC (monitored supply input), and Pin 3 is GND (0 V reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Drives low when VCC falls below threshold or push-button is pressed; floats high otherwise via internal pull-up. |
| VCC | Supply voltage input | Monitored rail; powers internal circuitry and sets comparator reference; accepts 1.2 V to 5.5 V. |
| GND | Ground reference | 0 V return path for all internal functions and reset output sink current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pull-up resistor | 5.5 kΩ typical (3.1–7.5 kΩ range); eliminates external component while ensuring robust logic-high level at reset input. |
| Manual reset support | Dedicated push-button interface with sub-microsecond detection and guaranteed 150 ms reset assertion; no firmware or external debounce needed. |
| Precision voltage monitoring | ±2.2% threshold accuracy over temperature; maintains tight trip point control across −40°C to +105°C without calibration. |
| Low quiescent current | ≤10 µA at 3.6 V; reduces standby power in always-on systems and extends battery life in portable devices. |
| Industrial temperature grade | Qualified from −40°C to +105°C; meets reliability requirements for factory automation, motor drives, and telecom infrastructure. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor with manual reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM1811-10ARTZ-RL7 | Same 4.35 V threshold, SOT-23 package, but lacks push-button reset functionality; open-drain output only. | Not suitable where field-serviceable manual reset is required; limited to automatic reset-only use cases. | Select when board layout already includes external push-button circuitry or reset is purely supply-driven. |
| MAX809SEUR+T | 4.63 V threshold (not 4.35 V); 140 ms reset timeout; no integrated push-button support; requires external pull-up. | Cannot replace ADM1813-10ART-RL7 without modifying reset timing and adding external components. | Choose only if 4.63 V trip point aligns with system margin requirements and manual reset is handled elsewhere. |
Compared with ADM1811-10ARTZ-RL7 and MAX809SEUR+T, the ADM1813-10ART-RL7 uniquely combines precise 4.35 V monitoring, integrated pull-up, and native push-button reset in a single SOT-23 package-reducing BOM count and PCB area while enabling field-serviceability.

FAQ
What is the exact reset threshold voltage of the ADM1813-10ART-RL7?
The ADM1813-10ART-RL7 has a nominal reset threshold of 4.35 V, with a guaranteed range of 4.25 V (minimum) to 4.49 V (maximum) across −40°C to +105°C. This value is specified in Table 1 of the Rev. F datasheet and applies directly to the ADM1813-10ART-RL7 variant, confirming its suitability for monitoring nominal 5 V supplies with appropriate headroom.
Does the ADM1813-10ART-RL7 require an external pull-up resistor?
No, the ADM1813-10ART-RL7 includes an internal pull-up resistor with a typical value of 5.5 kΩ (range 3.1 kΩ to 7.5 kΩ). This eliminates the need for an external component and allows direct connection to standard CMOS reset inputs, reducing bill-of-materials count and PCB footprint compared to open-drain reset ICs without integrated pull-ups.
Can the ADM1813-10ART-RL7 be used with a push-button for manual reset?
Yes, the ADM1813-10ART-RL7 explicitly supports manual reset via an external push-button switch connected between the RST pin and GND. When pressed, the button pulls RST low; upon release, the device asserts a clean 150 ms reset pulse regardless of contact bounce, as confirmed in the "ADM1813 AND ADM1818" section of the datasheet.
What package type does the ADM1813-10ART-RL7 use?
The ADM1813-10ART-RL7 uses the 3-lead SOT-23 (RT-3) package, as indicated by the "ART" suffix in the part number and verified in the Ordering Guide on page 9 of the Rev. F datasheet. Its JEDEC TO-236-AB compliant footprint measures 2.90 mm × 1.30 mm × 1.02 mm and supports reflow soldering per industry standards.
What is the supply current consumption of the ADM1813-10ART-RL7?
The ADM1813-10ART-RL7 draws ≤10 µA of supply current at VCC = 3.6 V and TA = −40°C to +105°C, as specified in Table 1 of the datasheet. At 5.5 V, maximum current rises to 16 µA. This ultra-low quiescent current makes it suitable for always-on systems and battery-buffered applications where standby power must be minimized.
