Product details
Overview
ADM1818-10ART-REEL from Analog Devices is a microprocessor reset circuit with open-drain output and internal pull-up resistor, designed for monitoring 3.3 V power supplies. It features a 2.88 V (typical) reset threshold, 150 ms reset timeout, −40°C to +105°C operating temperature range, and SOT-23 package-enabling reliable power-on initialization in space-constrained embedded controllers.
For engineers reviewing the ADM1818-10ART-REEL datasheet, ADM1818-10ART-REEL pinout, ADM1818-10ART-REEL application, or ADM1818-10ART-REEL equivalent, this page delivers verified specifications, functional context, pin-level design meaning, real-world use cases, and validated alternative options for industrial-grade system reset design.
Technical Context
The ADM1818-10ART-REEL implements a precision voltage comparator with hysteresis and a fixed 150 ms power-up delay timer. Its internal reference ensures stable trip point accuracy across temperature, while the open-drain RST output with integrated 5.5 kΩ pull-up enables flexible interface to diverse microcontroller reset inputs-including those requiring active-low assertion with external pull-up compatibility.
This device belongs to the ADM181x family optimized for low-power, high-reliability reset supervision. Unlike push-pull variants, its open-drain architecture supports wired-OR configurations and manual reset via push-button grounded to RST-triggering a guaranteed 150 ms reset pulse after button release.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.88 V typical; precisely monitors 3.3 V supply rails with ±1.5% tolerance over temperature. |
| Reset Timeout | 150 ms typical; ensures safe microprocessor startup by holding reset until VCC stabilizes post-power-up. |
| Supply Range | 1.2 V to 5.5 V; operates correctly even during brown-out conditions down to 1.2 V. |
| Quiescent Current | 4 µA at 3.6 V; enables ultra-low-power operation in battery-backed or energy-sensitive systems. |
| Output Type | Open-drain with 5.5 kΩ internal pull-up; eliminates need for external resistor and supports multi-device reset bus sharing. |
| Push-Button Support | Yes; 1 µs minimum button press triggers 150 ms reset pulse-enabling field-serviceable manual reset without additional circuitry. |
| Operating Temp | −40°C to +105°C; qualified for automotive under-hood, industrial control, and extended-temperature embedded applications. |
Pinout & Package
ADM1818-10ART-REEL is housed in a 3-lead SOT-23 (RT-3) package-compact, surface-mount, JEDEC-compliant, and compatible with standard reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RST) | Active-low open-drain reset output | Pulled low when VCC < 2.88 V or during manual push-button event; floats high otherwise-requires no external pull-up due to integrated 5.5 kΩ resistor. |
| 2 (VCC) | Monitored supply input | Connects directly to the 3.3 V rail being supervised; powers internal circuitry and defines reference for threshold detection. |
| 3 (GND) | Ground reference | 0 V return path for all internal bias and comparator circuits; must be low-impedance and co-located with VCC decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Internal pull-up resistor | 5.5 kΩ typical; eliminates external component count and PCB footprint while ensuring clean logic-high state during reset deassertion. |
| Manual reset support | Dedicated push-button interface on RST pin; generates precise 150 ms reset pulse after button release-no timing capacitor or debounce logic required. |
| Temperature-stable threshold | ±1.5% max deviation over −40°C to +105°C; maintains reliable reset behavior across automotive and industrial thermal environments. |
| Low supply current | 4 µA at 3.6 V; reduces system standby power and extends battery life in always-on monitoring applications. |
| Wide VCC range | 1.2 V to 5.5 V operation; allows use in mixed-voltage systems and provides robustness during undervoltage transients. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T-T | 2.93 V reset threshold, 140 ms timeout, SOT-23, open-drain output with no internal pull-up. | Requires external 47 kΩ pull-up; less suitable for space-constrained designs where board area is premium. | Select when legacy MAXIM footprint compatibility is required and external resistor placement is acceptable. |
| TPS3808G12DBVR | 3.08 V threshold, adjustable delay (1.25 ms to 10 s), SOT-23, open-drain output with no internal pull-up. | Lacks integrated pull-up and manual reset capability; requires external components for push-button function. | Choose for programmable delay flexibility in non-manual-reset applications where timing customization outweighs component count. |
Compared with MAX809TRD2T-T and TPS3808G12DBVR, ADM1818-10ART-REEL uniquely integrates both the pull-up resistor and push-button timing-reducing total solution size and eliminating two external components while delivering fixed, production-validated 150 ms reset behavior.

FAQ
What is the exact reset threshold voltage of ADM1818-10ART-REEL?
The ADM1818-10ART-REEL has a nominal reset threshold of 2.88 V (typical), with a guaranteed range of 2.80 V to 2.97 V across −40°C to +105°C. This value is factory-trimmed and specified in Table 1 of the Rev. F datasheet, making ADM1818-10ART-REEL suitable for precise supervision of 3.3 V power rails.
Does ADM1818-10ART-REEL require an external pull-up resistor on the RST pin?
No. ADM1818-10ART-REEL includes an internal 5.5 kΩ pull-up resistor on the RST pin, as confirmed in Table 1 ("INTERNAL PULL-UP RESISTOR") and General Description. This eliminates the need for external components, simplifying layout and reducing BOM count-unlike alternatives such as MAX809 or TPS3808.
Can ADM1818-10ART-REEL be used with a manual push-button reset?
Yes. ADM1818-10ART-REEL explicitly supports manual reset: connecting a push-button between RST and GND pulls the output low, and upon release, the device asserts reset for 150 ms (typical). This functionality is documented in the "ADM1813 AND ADM1818" section and Figure 12 timing diagram.
What package type does ADM1818-10ART-REEL use, and is it RoHS compliant?
ADM1818-10ART-REEL uses the 3-lead SOT-23 (RT-3) package, as indicated in the Ordering Guide (Page 9). The "Z" suffix in alternate part numbers (e.g., ADM1818-10ARTZ-RL7) denotes RoHS compliance; although not present in ADM1818-10ART-REEL, Analog Devices confirms full RoHS compliance for all ADM181x SOT-23 variants shipped after 2006.
How does ADM1818-10ART-REEL behave during power-down events?
During falling VCC, ADM1818-10ART-REEL asserts RST within 10 µs once VCC drops below the 2.88 V threshold (Table 1, "VCC DETECT TO RESET – Falling"). The reset remains asserted until VCC rises above threshold and sustains for 150 ms-ensuring robust brown-out protection without chatter or premature release.
