Product details
Overview
ADM1813-5ART-RL7 from Analog Devices is a 3-lead 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-on.
For engineers reviewing the ADM1813-5ART-RL7 datasheet, ADM1813-5ART-RL7 pinout, ADM1813-5ART-RL7 application, or ADM1813-5ART-RL7 equivalent, key selection criteria include reset threshold tolerance (±0.13 V), open-drain output sink current (8 mA), operating temperature range (−40°C to +105°C), and compatibility with manual reset switches.
Technical Context
The ADM1813-5ART-RL7 implements a precision voltage comparator with hysteresis and a fixed 150 ms power-up delay timer. Its internal reference achieves ±1.5% trip point accuracy over temperature, and the open-drain RST output supports bidirectional reset signaling via external pull-up or direct connection to microcontroller reset inputs.
Designed for 5 V supply monitoring, it features a dedicated push-button interface: pressing the button pulls RST low, and upon release, the device asserts reset for ≥150 ms. The internal 5.5 kΩ pull-up eliminates need for external components in standard configurations.
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 brownout. |
| Reset Timeout | 150 ms typical (100–250 ms range); provides sufficient time for power supply stabilization before system release. |
| Supply Voltage Range | 1.2 V to 5.5 V; supports operation across wide input conditions while monitoring 5 V rails. |
| Output Sink Current | 8 mA at VOUT = 0.4 V; drives standard CMOS/TTL reset inputs without external buffering. |
| Quiescent Current | 9–16 µA at VCC = 5.5 V; enables ultra-low-power operation in battery-backed systems. |
| Operating Temperature | −40°C to +105°C; qualified for industrial and automotive under-hood environments. |
| Internal Pull-Up | 5.5 kΩ typical (3.1–7.5 kΩ); eliminates external resistor requirement for open-drain reset assertion. |
Pinout & Package
ADM1813-5ART-RL7 is housed in a 3-lead SOT-23 (RT-3) package, measuring 2.90 mm × 1.30 mm × 1.02 mm, with gull-wing leads and JEDEC TO-236-AB compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low open-drain reset output | Drives low during reset; floats high otherwise; internal 5.5 kΩ pull-up enables direct MCU interface without external components. |
| VCC | Supply voltage input | Monitored 5 V rail; also powers internal comparator and timer; operates down to 1.2 V for brownout detection. |
| GND | Ground reference | 0 V return path for all internal circuitry; must be connected to system ground plane for accurate threshold sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Push-button reset support | 1 µs minimum button press triggers 150 ms guaranteed reset pulse-enables field service recovery without power cycle. |
| Integrated pull-up resistor | 5.5 kΩ typical value eliminates external component count and PCB footprint for standard reset bus configurations. |
| Fixed 150 ms reset timeout | Guaranteed delay ensures stable VCC before releasing reset-prevents premature CPU execution during power ramp. |
| Wide temperature operation | −40°C to +105°C rating supports deployment in harsh industrial enclosures and automotive ECUs. |
| Low quiescent current | ≤16 µA max at 5.5 V enables use in always-on subsystems with minimal standby power impact. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
Use Scenario: Power sequencing in programmable logic controller backplanes where 5 V logic rails must stabilize before FPGA configuration begins. IC Role / Device Role / Timing Role: Monitors main 5 V supply and asserts active-low reset to FPGA and microcontroller until voltage exceeds 4.62 V and remains stable for 150 ms. Use Value: Prevents configuration corruption by ensuring FPGA startup occurs only after clean power delivery-eliminates need for discrete RC timing networks. | Use Scenario: Reset coordination in body control units managing door locks, lighting, and window motors powered from vehicle 5 V regulator. IC Role / Device Role / Timing Role: Provides deterministic reset pulse synchronized to 5 V rail rise time, with manual override via dashboard reset switch.

Use Scenario: Battery-powered portable ultrasound device requiring fail-safe boot sequence after cold start or low-battery recovery. IC Role / Device Role / Timing Role: Detects 5 V DC-DC output from Li-ion charger and holds ARM Cortex-M4 in reset until full regulation is achieved. Use Value: Ultra-low 16 µA supply current extends battery life between charges; 105°C rating accommodates sealed enclosure thermal buildup. | Use Scenario: Multi-rail power management in fanless edge routers where 5 V auxiliary rail powers PHYs and management microcontrollers. IC Role / Device Role / Timing Role: Generates synchronized reset to multiple ICs using open-drain wired-OR topology with shared pull-up. Use Value: Internal 5.5 kΩ pull-up simplifies board layout-no external resistor needed for common reset bus implementation. |
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 | 4.63 V threshold, 140 ms timeout, SC70-3 package, no push-button support | Lacks manual reset capability; requires external pull-up for open-drain output | Select when push-button function is unnecessary and SC70 footprint is preferred. |
| TPS3808G15DBVR | 4.63 V threshold, adjustable timeout (1–10 s), SOT-23-6 package, higher quiescent current (12 µA min) | Requires external capacitor for timing; larger package increases board area | Choose when extended reset duration or programmability justifies added BOM cost and layout space. |
Compared with MAX809TRD2T-T and TPS3808G15DBVR, the ADM1813-5ART-RL7 uniquely integrates push-button reset and internal pull-up in SOT-23, reducing component count and enabling field-serviceable designs without sacrificing industrial temperature range or precision threshold accuracy.

FAQ
What is the exact reset threshold voltage for ADM1813-5ART-RL7?
The ADM1813-5ART-RL7 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 specification is confirmed in Table 1 of the Rev. F datasheet and applies specifically to the -5 variant, which is the designation encoded in the ADM1813-5ART-RL7 part number.
Does ADM1813-5ART-RL7 require an external pull-up resistor on the RST pin?
No, ADM1813-5ART-RL7 does not require an external pull-up resistor. It integrates a 5.5 kΩ typical internal pull-up resistor on the open-drain RST output, as explicitly stated in Table 1 under "INTERNAL PULL-UP RESISTOR" and confirmed in the ADM1813/ADM1818 functional description on Page 7.
Can ADM1813-5ART-RL7 be used with a manual push-button reset switch?
Yes, ADM1813-5ART-RL7 supports manual push-button reset: connecting a switch between RST and GND pulls the output low, and upon release, the device asserts reset for 150 ms typical. This behavior is documented in the "ADM1813 AND ADM1818" section (Page 7) and Figure 12 timing diagram.
What package type is used by ADM1813-5ART-RL7?
ADM1813-5ART-RL7 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 (Page 9). Its dimensions are 2.90 mm × 1.30 mm × 1.02 mm, compliant with JEDEC TO-236-AB standards.
What is the operating temperature range for ADM1813-5ART-RL7?
ADM1813-5ART-RL7 is rated for operation from −40°C to +105°C, as specified in the Ordering Guide (Page 9) and Absolute Maximum Ratings table (Page 4). This full industrial temperature range is guaranteed for all electrical parameters in the datasheet's specifications section.
