Product details
Overview
ADM1818-5ART-REEL7 from Analog Devices is a 3-pin SOT-23 open-drain microprocessor reset circuit with internal pull-up resistor, 3.06 V typical reset threshold, 150 ms reset timeout, and −40°C to +105°C operating range-designed for reliable power-on reset in 3.3 V embedded systems.
For engineers reviewing the ADM1818-5ART-REEL7 datasheet, ADM1818-5ART-REEL7 pinout, ADM1818-5ART-REEL7 application, or ADM1818-5ART-REEL7 equivalent, key selection factors include trip point accuracy (±1.5% over temperature), push-button reset support, ultra-low quiescent current (≤10 µA at 3.6 V), and compatibility with microcontroller reset inputs requiring active-low open-drain assertion.
Technical Context
The ADM1818-5ART-REEL7 implements a precision voltage comparator with built-in hysteresis and a fixed 150 ms power-up delay timer. Its internal pull-up resistor (5.5 kΩ typical) eliminates external components when interfacing with standard CMOS reset inputs.
It supports manual reset via push-button connected between RST and GND, generating a guaranteed 150 ms reset pulse after button release. The device asserts reset when VCC falls below 3.06 V (typical) and holds reset active for ≥100 ms after VCC rises above threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.06 V typical (2.98–3.15 V min/max); monitors 3.3 V supply with 7.3% headroom for brownout detection |
| Reset Timeout | 150 ms typical (100–250 ms min/max); ensures stable power-up before system initialization |
| Supply Range | 1.2 V to 5.5 V; operates across wide input range while maintaining accurate threshold |
| Quiescent Current | ≤10 µA at 3.6 V; enables low-power battery-backed or always-on monitoring |
| Output Type | Open-drain with 5.5 kΩ internal pull-up; directly drives standard microcontroller reset pins without external resistor |
| Push-Button Response | 1 µs detect time, 150 ms reset hold after release; supports user-initiated safe system restart |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood environments |
Pinout & Package
ADM1818-5ART-REEL7 is housed in a 3-lead SOT-23 (RT-3) package, JEDEC-compliant, with 2.90 mm × 1.30 mm footprint and 1.12 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low open-drain reset output | Pulled low during reset condition; floats high (via internal 5.5 kΩ resistor) otherwise-compatible with CMOS/LVTTL reset inputs |
| VCC | Supply voltage input | Monitored rail; powers internal circuitry and sets comparator reference; accepts 1.2–5.5 V |
| GND | Ground reference | 0 V return path for all internal functions and reset output sink current |
Key Features
| Feature | Design Value |
|---|---|
| Internal pull-up resistor | 5.5 kΩ typical (3.1–7.5 kΩ range); removes need for external pull-up, saving PCB space and BOM cost |
| Guaranteed reset timeout | 150 ms typical with ±33% tolerance; ensures sufficient power stabilization before processor release |
| Push-button reset interface | Validated 1 µs detection and 150 ms post-release hold; enables field-serviceable system recovery |
| Low supply current | ≤10 µA at 3.6 V; extends battery life in portable or energy-harvesting applications |
| Wide temperature operation | −40°C to +105°C; maintains trip point accuracy and timing stability across industrial thermal profiles |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
Use Scenario: Power cycling due to load dump or battery disconnect in factory automation controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T-T | 3.08 V reset threshold (±2.5%), 140 ms timeout, SOT-23-3, no push-button support | Lacks manual reset capability; requires external pull-up for open-drain output | Select when push-button functionality is unnecessary and tighter threshold tolerance is not required |
| TPS3808G30DBVR | 3.0 V threshold (±0.5%), 200 ms timeout, SOT-23-6, active-low push-pull output | Higher accuracy but larger package and no integrated pull-up; push-pull eliminates external resistor but lacks push-button interface | Choose for precision-critical applications where board space allows 6-pin package and manual reset is handled elsewhere |
Compared with MAX809TRD2T-T and TPS3808G30DBVR, the ADM1818-5ART-REEL7 uniquely combines 3.06 V threshold accuracy, integrated pull-up, and validated push-button reset in a 3-pin SOT-23-reducing component count and enabling field-serviceable recovery in space-constrained designs.

FAQ
What is the exact reset threshold voltage of ADM1818-5ART-REEL7?
The ADM1818-5ART-REEL7 has a nominal reset threshold of 3.06 V, with guaranteed limits of 2.98 V (min) and 3.15 V (max) over −40°C to +105°C. This value is specified in Table 1 of the Rev. F datasheet and applies exclusively to the -5 variant, which targets 3.3 V supply monitoring.
Does ADM1818-5ART-REEL7 require an external pull-up resistor?
No, ADM1818-5ART-REEL7 includes an internal pull-up resistor (5.5 kΩ typical, 3.1–7.5 kΩ range) on the RST pin. This eliminates the need for an external component when driving standard CMOS reset inputs, simplifying layout and reducing BOM count.
Can ADM1818-5ART-REEL7 be used with a manual push-button reset?
Yes, ADM1818-5ART-REEL7 supports manual reset via a push-button switch connected between RST and GND. Pressing the button pulls RST low; upon release, the device guarantees a 150 ms reset pulse, as confirmed in the "ADM1813 AND ADM1818" section of the datasheet.
What package type does ADM1818-5ART-REEL7 use?
ADM1818-5ART-REEL7 uses the 3-lead SOT-23 (RT-3) package, per the Ordering Guide on page 9 of the Rev. F datasheet. It measures 2.90 mm × 1.30 mm with 1.12 mm height and complies with JEDEC TO-236-AB standards.
What is the maximum supply voltage ADM1818-5ART-REEL7 can monitor?
ADM1818-5ART-REEL7 operates with a supply voltage range of 1.2 V to 5.5 V, as stated in the Absolute Maximum Ratings table. While its 3.06 V threshold targets 3.3 V rails, it remains functional up to 5.5 V-enabling flexibility in multi-rail systems where VCC may exceed nominal monitoring voltage.
