Product details
Overview
ADM1813-10ARTZ-RL7 from Analog Devices is a 3-pin open-drain microprocessor reset circuit with internal 5.5 kΩ pull-up resistor, 4.35 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 ADM1813-10ARTZ-RL7 datasheet, ADM1813-10ARTZ-RL7 pinout, ADM1813-10ARTZ-RL7 application, or ADM1813-10ARTZ-RL7 equivalent, this device serves as a low-power, space-constrained voltage supervisor requiring precise power-on reset timing, manual reset integration, and compatibility with standard 3.3 V–5 V logic interfaces.
Technical Context
The ADM1813-10ARTZ-RL7 implements a precision bandgap reference and comparator-based voltage detection circuit with built-in 150 ms power-up delay to ensure stable VCC before releasing reset. Its open-drain output with integrated 5.5 kΩ pull-up eliminates external components while supporting wired-OR configurations.
It features push-button reset functionality: a momentary ground connection to RST triggers a guaranteed 150 ms active-low reset pulse after release, with 1 µs minimum button press detection. The device operates across −40°C to +105°C and draws only 4–10 µA at 3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.25 V (min) to 4.49 V (max), typical 4.35 V - ensures reliable detection of 5 V supply brownout below 4.35 V. |
| Reset Timeout | 100–250 ms, typical 150 ms - provides sufficient time for power supply stabilization before system initialization. |
| Supply Current | 4 µA (typ) at 3.6 V - enables ultra-low-power operation in battery-backed or energy-sensitive applications. |
| Output Type | Open-drain with internal 3.1–7.5 kΩ pull-up - simplifies interface to microcontroller reset inputs without external resistors. |
| Push-Button Support | 1 µs minimum detect time, 150 ms reset hold after release - enables robust manual reset with minimal PCB footprint. |
| Operating Temp | −40°C to +105°C - qualified for industrial and automotive under-hood environments. |
| Package | SOT-23 (RT-3) - 3-pin surface-mount package compatible with high-density PCB layouts and automated assembly. |
Pinout & Package
ADM1813-10ARTZ-RL7 uses a 3-lead SOT-23 (RT-3) package with standard top-view pinout: Pin 1 = RST (active-low open-drain reset output), Pin 2 = VCC (monitored supply input), Pin 3 = GND (0 V reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low open-drain reset output | Drives low during reset condition; floats high when released, pulled up internally to VCC via ~5.5 kΩ resistor. |
| VCC | Monitored supply voltage input | Input voltage range 1.2–5.5 V; reset asserts when VCC falls below threshold and holds for 150 ms after recovery. |
| GND | Ground reference | 0 V return path for internal reference and comparator; must be connected directly to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pull-up resistor | 5.5 kΩ typical - eliminates need for external pull-up, reducing BOM count and layout area. |
| Guaranteed reset timeout | 150 ms typical after VCC rise - ensures safe microprocessor startup even with slow-ramping supplies. |
| Push-button reset interface | Detects ≥1 µs ground pulse on RST and generates clean 150 ms reset - supports compact front-panel reset buttons. |
| Low quiescent current | 4 µA at 3.6 V - extends battery life in portable or always-on monitoring applications. |
| Wide temperature range | −40°C to +105°C operation - suitable for industrial control, automotive ECUs, and outdoor 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 | 4.63 V fixed threshold, no internal pull-up, requires external resistor; 140 ms reset timeout. | Lacks push-button reset function; not suitable for designs requiring manual reset without added circuitry. | Select when only basic 5 V reset is needed and board space allows external pull-up. |
| TPS3808G15DBVR | Adjustable threshold (via resistor divider), 2% accuracy, 200 ms timeout, higher 12 µA supply current. | Supports custom trip points but consumes >2× more current and requires two external resistors. | Choose for precision threshold tuning where 4.35 V fixed point is insufficient. |
Compared with MAX809TRD2T and TPS3808G15DBVR, the ADM1813-10ARTZ-RL7 delivers integrated push-button support and internal pull-up in a smaller footprint, making it optimal for cost-sensitive, space-constrained 5 V systems needing both automatic and manual reset capability.

FAQ
What is the exact reset threshold voltage for ADM1813-10ARTZ-RL7?
The ADM1813-10ARTZ-RL7 has a guaranteed reset threshold range of 4.25 V (minimum) to 4.49 V (maximum), with a typical value of 4.35 V. This specification applies across the full operating temperature range of −40°C to +105°C and ensures reliable detection of 5 V supply undervoltage conditions before system initialization.
Does ADM1813-10ARTZ-RL7 require an external pull-up resistor?
No, ADM1813-10ARTZ-RL7 includes an internal pull-up resistor with a nominal value of 5.5 kΩ (range 3.1–7.5 kΩ). This eliminates the need for an external component on the RST line, simplifying design and reducing PCB area - a key advantage over alternatives like the MAX809 series.
Can ADM1813-10ARTZ-RL7 be used with a manual push-button reset?
Yes, ADM1813-10ARTZ-RL7 explicitly supports push-button reset: connecting a momentary switch between RST and GND triggers a clean 150 ms active-low reset pulse after release, with detection sensitivity down to 1 µs. This feature is confirmed in the datasheet's "ADM1813 AND ADM1818" section and functional diagrams.
What package type does ADM1813-10ARTZ-RL7 use?
ADM1813-10ARTZ-RL7 uses the 3-lead SOT-23 (RT-3) package, as indicated by the "RTZ" suffix and verified in the Ordering Guide. It measures 2.90 mm × 1.30 mm × 1.02 mm and is RoHS-compliant (Z suffix), suitable for high-volume automated assembly and dense PCB layouts.
How does ADM1813-10ARTZ-RL7 handle power-up timing?
ADM1813-10ARTZ-RL7 asserts reset while VCC is below threshold and holds reset active for a guaranteed 100–250 ms (typical 150 ms) after VCC rises above the trip point. This built-in delay ensures stable power supply conditions before releasing the microprocessor reset line, preventing premature boot and firmware corruption.
