Product details
Overview
ADM810LARTZ-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 4.63 V reset threshold, and operation down to 1.0 V VCC. It provides 240 ms (typical) power-on reset timeout, consumes 17 μA at 3.6 V, and is qualified for −40°C to +125°C industrial/automotive environments. It monitors 5 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810LARTZ-REEL7 datasheet, ADM810LARTZ-REEL7 pinout, ADM810LARTZ-REEL7 application, or ADM810LARTZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), SOT-23-3 package compatibility, guaranteed operation below 1.2 V VCC, temperature-stable threshold (±0.07 V over −40°C to +125°C), and absence of external pull-up requirement.
Technical Context
The ADM810LARTZ-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reference circuit maintains ±0.07 V threshold accuracy across −40°C to +125°C, enabling reliable brownout detection even during fast transients on VCC.
Unlike open-drain variants, the ADM810LARTZ-REEL7 features a push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min) and sinking 1.2 mA at VTH(min), eliminating need for external pull-up resistors in 5 V or 3.3 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (nominal); ±0.07 V tolerance over −40°C to +85°C ensures stable 5 V rail monitoring without false resets. |
| Reset Polarity | Active-high; asserts high during power-up/brownout and holds for 240 ms (typical), directly compatible with microprocessors requiring active-high reset input. |
| VCC Operating Range | 1.0 V to 5.5 V; guarantees functional reset assertion even as supply collapses to 1.0 V, critical for fail-safe shutdown sequencing. |
| Supply Current | 17 μA (typical at VCC < 3.6 V, −40°C to +85°C); enables integration into battery-powered portable instrumentation without measurable battery drain. |
| Package | SOT-23-3 (RT-3); industry-standard 3-pin footprint with 2.90 mm × 1.30 mm body, compatible with automated SMT assembly and legacy board layouts. |
| Temperature Range | −40°C to +125°C; qualified for under-hood automotive, industrial PLC, and high-reliability embedded applications. |
Pinout & Package
ADM810LARTZ-REEL7 uses a 3-lead SOT-23 (RT-3) package with gull-wing leads, 1.9 mm pitch, and JEDEC TO-236-AB compliance. Thermal impedance is 270°C/W (θJA).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input; connects directly to 5 V rail being supervised; supports operation down to 1.0 V. |
| 2 | RESET | Active-high push-pull output; drives high during fault conditions and remains high for 240 ms after VCC exceeds 4.63 V. |
| 3 | GND | Ground reference for comparator and timer; must be connected to system ground plane for accurate threshold sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects transients ≤100 μs duration at VTH – VCC = 100 mV, preventing spurious resets during switching noise. |
| Low-voltage operation | Functional reset assertion down to VCC = 1.0 V ensures deterministic behavior during deep brownout or controlled power-down. |
| Push-pull output | No external pull-up required; sinks 1.2 mA and sources 150 μA, simplifying interface to CMOS/TTL inputs across 1.8–5 V logic families. |
| Precision threshold | ±0.07 V max deviation over −40°C to +85°C eliminates need for system-level calibration in temperature-critical applications. |
| Ultra-low quiescent current | 17 μA typical at 3.6 V enables >10-year battery life in always-on sensor nodes using coin-cell power. |
Applications
| Industrial PLC Controllers | Automotive Body Control Modules |
|---|---|
Use Scenario: Supervises 5 V microcontroller supply in programmable logic controllers exposed to wide ambient temperature swings and EMI-rich factory floors.

| Medical Diagnostic Handhelds | Smart Energy Meters |
Use Scenario: Powers ARM-based processor in portable ultrasound or glucose monitor where battery life and cold-start reliability are critical. IC Role / Device Role / Timing Role: Delivers active-high reset with 240 ms minimum timeout to prevent premature execution before analog front-end stabilization. Use Value: 17 μA supply current extends single-charge battery life beyond 12 months; operates reliably at −40°C for field-deployed units. |
Use Scenario: Supervises 5 V supply feeding metrology IC and RF modem in ANSI C12.22-compliant smart meters installed outdoors. IC Role / Device Role / Timing Role: Asserts active-high reset during AC mains dropout or capacitor discharge events, holding MCU in safe state until backup power engages. Use Value: 4.63 V threshold precisely matches 5 V rail tolerance; −40°C to +125°C rating ensures operation in unventilated meter enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809LARTZ-REEL7 | Same 4.63 V threshold and SOT-23 package, but active-low push-pull RESET output. | Requires inverted reset logic handling in MCU firmware or external inverter; unsuitable for systems mandatorily requiring active-high. | Select only if existing design uses active-low reset architecture and layout cannot accommodate signal inversion. |
| TPS3808G01DBVR | 4.63 V threshold, active-high push-pull, but 35 μA supply current and 200 ms min timeout (vs. 240 ms typ for ADM810). | Higher current draw reduces battery life in portable devices; shorter timeout may not meet strict MCU initialization timing requirements. | Prefer when TI ecosystem alignment or extended voltage range (up to 6.5 V) is prioritized over ultra-low power and precise timeout. |
Compared with ADM809LARTZ-REEL7, ADM810LARTZ-REEL7 eliminates need for signal inversion logic; compared with TPS3808G01DBVR, it delivers 2.1× lower quiescent current and tighter reset timeout control-critical for energy-constrained and timing-sensitive embedded systems.

FAQ
What is the reset timeout duration for ADM810LARTZ-REEL7?
The ADM810LARTZ-REEL7 provides a typical power-on reset timeout of 240 ms, with a guaranteed minimum of 140 ms and maximum of 460 ms over −40°C to +85°C. This ensures sufficient time for microprocessor core and peripherals to stabilize before release from reset, meeting stringent boot timing requirements in safety-critical systems.
Does ADM810LARTZ-REEL7 require an external pull-up resistor?
No, ADM810LARTZ-REEL7 features a push-pull RESET output and does not require an external pull-up resistor. It can source 150 μA at 1.8 V < VCC < VTH(min) and sink 1.2 mA at VTH(min), enabling direct connection to standard CMOS or TTL inputs without additional components.
What is the operating voltage range of ADM810LARTZ-REEL7?
The ADM810LARTZ-REEL7 operates from VCC = 1.0 V to 5.5 V across −40°C to +125°C. Its ability to assert reset down to 1.0 V VCC ensures fail-safe behavior during deep brownout conditions, making it suitable for applications where supply collapse must trigger controlled shutdown.
How does ADM810LARTZ-REEL7 handle voltage transients on the VCC line?
ADM810LARTZ-REEL7 incorporates a glitch-immune reset comparator that rejects transients ≤100 μs duration when VTH – VCC ≥ 100 mV (per Figure 11). This prevents false resets caused by switching noise or ESD events, ensuring reliable operation in electrically noisy industrial and automotive environments.
Is ADM810LARTZ-REEL7 RoHS compliant?
Yes, ADM810LARTZ-REEL7 is RoHS compliant, indicated by the "Z" suffix in the part number per Analog Devices' ordering guide. It meets EU Directive 2011/65/EU and contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
