Product details
Overview
ADM1813-5ART-RL from Analog Devices is a 3-pin SOT-23 open-drain microprocessor reset circuit with internal 5.5 kΩ pull-up resistor, 4.62 V typical reset threshold, 150 ms reset timeout, and push-button reset capability. It monitors 5 V power supplies in embedded controllers and ensures safe system initialization after power-up.
For engineers reviewing the ADM1813-5ART-RL datasheet, ADM1813-5ART-RL pinout, ADM1813-5ART-RL application, or ADM1813-5ART-RL equivalent, this page delivers verified specifications, functional context, package details, real-world use cases, and validated alternative options for industrial and automotive reset supervision.
Technical Context
The ADM1813-5ART-RL implements a precision voltage comparator with hysteresis and a fixed 150 ms power-up delay timer to prevent premature microprocessor release during supply ramp-up. Its open-drain output with integrated 5.5 kΩ pull-up enables flexible logic-level interfacing without external components.
It supports manual reset via push-button connected between RST and GND, triggering a guaranteed 150 ms low pulse upon button release - a feature confirmed exclusive to ADM1813/ADM1818 variants per datasheet Section "ADM1813 AND ADM1818".
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.62 V typical (min 4.50 V, max 4.75 V); precisely monitors 5 V rails with ±2.7% tolerance. |
| Reset Timeout | 150 ms typical (100–250 ms range); provides stable delay for power supply stabilization before system boot. |
| Supply Range | 1.2 V to 5.5 V; operates across wide input while monitoring only VCC ≥ 4.5 V for reset assertion. |
| Quiescent Current | 9–16 µA at 5.5 V; ultra-low power consumption ideal for battery-backed or energy-sensitive systems. |
| Output Type | Open-drain with internal 5.5 kΩ pull-up; eliminates need for external resistor and simplifies PCB layout. |
| Push-Button Response | 1 µs detect time + 150 ms active-low pulse; enables reliable manual reset with no additional timing circuitry. |
| Operating Temp | −40°C to +105°C; qualified for industrial and under-hood automotive environments. |
Pinout & Package
ADM1813-5ART-RL is housed in a 3-lead SOT-23 (RT-3) package, RoHS-compliant, with 1.3 mm × 2.9 mm footprint and 1.1 mm height. Pin 1 = RST (active-low open-drain output), Pin 2 = VCC (monitored supply input), Pin 3 = GND (0 V reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST (Pin 1) | Active-low reset output | Open-drain output pulled up internally to VCC via 5.5 kΩ; sinks 8 mA when asserted; requires external pull-up only if interfacing to >5.5 V logic. |
| VCC (Pin 2) | Supply voltage input | Monitored rail input; device draws current from this pin; valid for 1.2–5.5 V operation but asserts reset only when VCC falls below 4.50 V. |
| GND (Pin 3) | Ground reference | 0 V return path for all internal circuitry and reset comparator; must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pull-up resistor | 5.5 kΩ internal pull-up eliminates external component and reduces BOM count in reset signal routing. |
| Manual push-button support | Dedicated timing path detects button press/release and guarantees 150 ms reset pulse - no external RC network required. |
| 150 ms power-up delay | Factory-trimmed timeout ensures consistent system initialization window across temperature and process variation. |
| Low supply current | ≤16 µA at 5.5 V enables use in always-on subsystems without compromising battery life or thermal budget. |
| Wide temperature range | −40°C to +105°C operation supports deployment in harsh environments including engine control units and industrial PLCs. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
Use Scenario: Power cycling due to load dump or battery disconnect in programmable logic controllers. IC Role / Device Role / Timing Role: Monitors 5 V auxiliary supply and holds MCU in reset until voltage stabilizes post-transient. Use Value: Prevents corrupted firmware execution by enforcing 150 ms minimum stabilization period before release. | Use Scenario: Cold-cranking event causing 5 V rail dip below specification during engine start. IC Role / Device Role / Timing Role: Detects VCC drop below 4.50 V and asserts active-low reset to safeguard CAN node initialization. Use Value: Ensures deterministic reset behavior across −40°C to +105°C, eliminating brownout-induced communication faults. |
| Embedded Network Gateway | Medical Diagnostic Instrument |
Use Scenario: Hot-swap of PoE-powered gateway requiring clean restart after power interruption. IC Role / Device Role / Timing Role: Provides push-button initiated reset independent of main supply state, using RST-to-GND switch. Use Value: Enables field service personnel to force full system reboot without cycling main power or accessing firmware. | Use Scenario: Dual-supply system where 5 V analog front-end must initialize before digital processor. IC Role / Device Role / Timing Role: Generates synchronized reset pulse to both domains using open-drain wired-OR topology. Use Value: Internal pull-up allows direct connection to multiple downstream reset inputs without level-shifting or contention risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor with push-button reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.63 V threshold, 140 ms timeout, no internal pull-up (requires external resistor), no push-button support. | Lacks manual reset functionality; suitable only for basic power-on reset without field service capability. | Select when cost sensitivity outweighs push-button requirement and board space permits external 47 kΩ pull-up. |
| TPS3808G15DBVR | 4.63 V threshold, adjustable timeout (1–10 s), push-button capable via external capacitor, no internal pull-up. | Requires external RC network for manual reset; offers longer timeout flexibility but increases component count. | Choose when system demands configurable reset duration or integration with existing TPS3808-based designs. |
Compared with MAX809SEUR+T and TPS3808G15DBVR, the ADM1813-5ART-RL uniquely combines factory-set 150 ms timing, integrated pull-up, and dedicated push-button logic in a 3-pin SOT-23 - reducing design complexity and validation effort for 5 V reset supervision.

FAQ
What is the exact reset threshold voltage for ADM1813-5ART-RL?
The ADM1813-5ART-RL has a nominal reset threshold of 4.62 V, with guaranteed minimum and maximum values of 4.50 V and 4.75 V respectively across −40°C to +105°C. This is specified in Table 1 of the Rev. F datasheet under "VCC TRIP POINT" for the -5 variant, confirming its suitability for precise 5 V supply monitoring.
Does ADM1813-5ART-RL require an external pull-up resistor?
No, ADM1813-5ART-RL does not require an external pull-up resistor. It integrates a 5.5 kΩ internal pull-up on the RST pin, as explicitly stated in Table 1 ("INTERNAL PULL-UP RESISTOR") and confirmed in the "ADM1813 AND ADM1818" section of the datasheet. This eliminates BOM items and layout overhead for standard 3.3 V or 5 V logic interfacing.
Can ADM1813-5ART-RL be used for manual reset via push-button?
Yes, ADM1813-5ART-RL supports manual reset via push-button - a feature exclusive to the ADM1813 and ADM1818 families. As described in Figure 11 and Section "ADM1813 AND ADM1818", connecting a switch between RST and GND generates a guaranteed 150 ms active-low reset pulse upon release, with 1 µs detection latency.
What package type is used by ADM1813-5ART-RL?
ADM1813-5ART-RL uses the 3-lead SOT-23 (RT-3) package, as indicated by the "RT-3 (SOT-23)" entry in the Ordering Guide for model ADM1813-5ART-RL. Its dimensions are 2.90 mm × 1.30 mm × 1.02 mm, compliant with JEDEC TO-236-AB standards and compatible with standard SOT-23 pick-and-place equipment.
Is ADM1813-5ART-RL qualified for automotive applications?
Yes, ADM1813-5ART-RL is qualified for automotive applications: it is rated for −40°C to +105°C operating temperature (Table 2, Absolute Maximum Ratings), features guaranteed reset timing across that range (Figure 6), and is listed in the datasheet Applications section as suitable for "Automotive systems". No AEC-Q200 stress testing is claimed, but its spec-grade performance meets common Tier-2 automotive subsystem requirements.
