Product details
Overview
ADM1813-5ARTZ-RL from Analog Devices is a 3-pin open-drain microprocessor reset circuit with internal pull-up resistor, 4.62 V typical reset threshold, 150 ms reset timeout, and push-button reset capability for 5 V supply monitoring in embedded systems.
For engineers reviewing the ADM1813-5ARTZ-RL datasheet, ADM1813-5ARTZ-RL pinout, ADM1813-5ARTZ-RL application, or ADM1813-5ARTZ-RL equivalent, this device delivers precise power-on reset timing, manual reset integration, and low-quiescent-current supervision suitable for space-constrained industrial and automotive microcontroller applications.
Technical Context
The ADM1813-5ARTZ-RL implements a precision voltage comparator with hysteresis and a fixed 150 ms power-up delay timer to ensure stable system initialization after VCC exceeds 4.62 V (typ). Its open-drain RST output includes an integrated 5.5 kΩ pull-up resistor, eliminating external components.
It supports manual reset via push-button connection between RST and GND, triggering a guaranteed 150 ms reset pulse after button release - validated for >1 µs button press duration. The device operates across −40°C to +105°C and draws only 9–16 µA at VCC = 5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.62 V typical (min 4.50 V, max 4.75 V); ensures reliable detection of 5 V supply stabilization before releasing reset. |
| Reset Timeout | 150 ms typical (100–250 ms range); provides sufficient time for power rail settling and clock stabilization pre-initialization. |
| Supply Current | 9–16 µA at VCC = 5.5 V; enables ultra-low-power operation in battery-backed or energy-sensitive systems. |
| Output Type | Open-drain with 5.5 kΩ internal pull-up (3.1–7.5 kΩ range); simplifies interface to diverse logic families without external resistor. |
| Push-Button Response | 1 µs detect-to-reset latency; guarantees immediate recognition of manual reset input for field service or recovery. |
| Operating Temp | −40°C to +105°C; qualified for under-hood automotive, industrial PLC, and extended-temperature embedded control. |
| Package | SOT-23 (RT-3); 3-pin, 2.9 mm × 1.3 mm footprint compatible with high-density PCB layouts. |
Pinout & Package
ADM1813-5ARTZ-RL is housed in a RoHS-compliant 3-lead SOT-23 (RT-3) package with gull-wing leads, JEDEC TO-236-AB compliant outline, and 0.95 mm nominal height.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output; floats high when VCC ≥ threshold, pulls low during reset or manual button press. |
| 2 | VCC | Monitored supply input; powers internal circuitry and serves as reference for threshold detection. |
| 3 | GND | Ground reference for comparator, timer, and output stage; must be low-impedance return path. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pull-up resistor | 5.5 kΩ typical (3.1–7.5 kΩ); eliminates external component count and layout area for reset line termination. |
| Manual push-button support | Dedicated RST/GND interface with 1 µs detection and 150 ms guaranteed timeout; enables field-recoverable system reset. |
| Fixed 150 ms reset delay | Factory-trimmed timing; ensures consistent power-rail stabilization window across temperature and process variation. |
| Low supply current | 9 µA min at 5.5 V; reduces standby power draw in always-on or battery-operated microcontroller subsystems. |
| Wide temperature range | −40°C to +105°C operation; supports deployment in engine control units, motor drives, and outdoor industrial equipment. |
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 | 4.63 V threshold, 140 ms timeout, no internal pull-up (requires external resistor), SOT-23-3 | Lacks integrated push-button reset support; requires external RC network for manual reset implementation | Select when cost sensitivity outweighs board space savings and manual reset is not required |
| TPS3808G01DBVR | 4.63 V threshold, adjustable timeout (1–10 s), push-pull output, no internal pull-up, SOT-23-5 | 5-pin package increases footprint; push-pull output incompatible with wired-OR reset buses without level-shifting | Choose when programmable timeout or higher drive strength (>20 mA sink) is needed for legacy MCU inputs |
Compared with MAX809TRD2T-T and TPS3808G01DBVR, ADM1813-5ARTZ-RL uniquely combines fixed 150 ms timing, internal pull-up, and push-button reset in a 3-pin SOT-23 - reducing BOM count and PCB area while enabling field-serviceable reset in compact designs.

FAQ
What is the exact reset threshold voltage for ADM1813-5ARTZ-RL?
The ADM1813-5ARTZ-RL has a nominal reset threshold of 4.62 V (typical), with guaranteed minimum and maximum values of 4.50 V and 4.75 V respectively over −40°C to +105°C. This threshold is factory-trimmed and applies specifically to the -5 variant, which targets 5 V supply monitoring.
Does ADM1813-5ARTZ-RL require an external pull-up resistor on the RST pin?
No. ADM1813-5ARTZ-RL includes an internal pull-up resistor of 5.5 kΩ (3.1–7.5 kΩ range) on the open-drain RST output, eliminating the need for external components. This allows direct connection to most microcontroller reset inputs without additional passives.
Can ADM1813-5ARTZ-RL be used with a manual push-button reset?
Yes. ADM1813-5ARTZ-RL explicitly supports manual reset: connecting a push-button between RST and GND triggers a guaranteed 150 ms active-low reset pulse upon button release, provided the press duration exceeds 1 µs - as confirmed in the ADM1813/ADM1818 section of the datasheet.
What is the operating temperature range of ADM1813-5ARTZ-RL?
ADM1813-5ARTZ-RL is rated for continuous operation from −40°C to +105°C, matching the extended industrial temperature grade. This qualification is documented in the Absolute Maximum Ratings table and Ordering Guide, confirming suitability for under-hood automotive and factory-floor applications.
Which package type does ADM1813-5ARTZ-RL use?
ADM1813-5ARTZ-RL uses the 3-lead SOT-23 (RT-3) package, as indicated by the "RT" suffix in the part number and verified in the Ordering Guide. It features gull-wing leads, JEDEC TO-236-AB compliance, and a 2.9 mm × 1.3 mm body size.
