Product details
Overview
ADM810TARTZ-REEL from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 3.08 V reset threshold, and operation down to 1.0 V VCC. It provides 240 ms (typical) power-on reset timeout, consumes 17 μA typical supply current, and is qualified for −40°C to +125°C industrial/automotive environments. It monitors 3.3 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810TARTZ-REEL datasheet, ADM810TARTZ-REEL pinout, ADM810TARTZ-REEL application, or ADM810TARTZ-REEL equivalent, key selection criteria include reset polarity (active-high), SOT-23-3 package compatibility, guaranteed operation at VCC ≥ 1.0 V, temperature-stable 3.08 V threshold, and absence of external pull-up requirement.
Technical Context
The ADM810TARTZ-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reset assertion remains valid even as VCC drops to 1.0 V, enabling reliable brownout detection in low-voltage systems.
Unlike open-drain variants (e.g., ADM803), the ADM810TARTZ-REEL features a push-pull output stage delivering both sourcing and sinking capability - supporting direct interface to CMOS inputs without external components. Its reset threshold exhibits ±0.15 V tolerance over −40°C to +125°C and 30 ppm/°C temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08 V (typical), ±0.15 V over full temperature range - ensures accurate 3.3 V rail monitoring with margin for supply ripple. |
| Reset Timeout | 240 ms (typical) power-on delay - holds microprocessor in reset until power stabilizes post-power-up. | Supply Current | 17 μA (typical) at VCC < 3.6 V - enables use in battery-powered or ultra-low-power embedded systems. |
| VCC Operating Range | 1.0 V to 5.5 V - supports operation during deep brownout and allows monitoring of sub-3 V supplies. |
| Output Type | Push-pull, active-high RESET - eliminates need for external pull-up resistor and simplifies PCB layout. |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive, industrial control, and harsh-environment applications. |
Pinout & Package
ADM810TARTZ-REEL is housed in a 3-lead SOT-23 (RT-3) package with 1.3 mm × 2.9 mm footprint and 0.95 mm height, compatible with standard pick-and-place equipment and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground reference | 0 V return path for internal comparator and output driver; must be connected to system ground plane. |
| 2 (VCC) | Supply input | Monitored voltage rail; powers internal circuitry and defines reset threshold reference point. |
| 3 (RESET) | Active-high push-pull output | Drives high when VCC ≥ 3.08 V (after timeout); drives low when VCC < 3.08 V or during reset assertion. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects fast transients up to 100 mV overdrive for ≤400 µs - prevents false resets from supply noise. |
| Low-VCC reset operation | Valid RESET signal asserted down to VCC = 1.0 V - ensures deterministic behavior during deep brownout. |
| Precision threshold stability | 30 ppm/°C tempco and ±0.15 V total variation over −40°C to +125°C - maintains timing integrity across thermal extremes. |
| No external components required | Integrated push-pull driver eliminates pull-up resistor - reduces BOM count and board area in space-constrained designs. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809TARTZ-REEL | Identical 3.08 V threshold, same SOT-23 package, but active-low RESET output. | Requires MCU with active-low reset input; incompatible with active-high-only reset pins. | Select when target MCU accepts only active-low reset signals and no level-shifting is desired. |
| MAX809TRD3-T | 3.08 V threshold, SOT-23-3, active-high RESET, but rated only to +85°C (not +125°C). | Not suitable for under-hood or extended-temperature industrial deployments requiring >+85°C operation. | Choose only for commercial-temperature applications where cost is prioritized over extended thermal qualification. |
Compared with ADM809TARTZ-REEL, ADM810TARTZ-REEL eliminates external level translation; compared with MAX809TRD3-T, it delivers guaranteed operation up to +125°C - critical for automotive and industrial reliability.

FAQ
What is the reset polarity of ADM810TARTZ-REEL?
The ADM810TARTZ-REEL provides an active-high RESET output: RESET is driven high when VCC is above the 3.08 V threshold (after the 240 ms timeout), and low when VCC falls below threshold or during power-up/brownout. This eliminates the need for external inverters or pull-up resistors required by active-low alternatives like ADM809TARTZ-REEL.
Does ADM810TARTZ-REEL require an external pull-up resistor?
No, ADM810TARTZ-REEL does not require an external pull-up resistor because it features a push-pull output stage capable of actively driving both high and low states. This distinguishes it from open-drain variants such as ADM803 and simplifies design by reducing component count and PCB routing complexity.
What is the minimum VCC at which ADM810TARTZ-REEL guarantees RESET assertion?
ADM810TARTZ-REEL guarantees valid RESET assertion down to VCC = 1.0 V across its full operating temperature range (−40°C to +125°C). Below this, the internal circuitry may cease functioning, but the device remains functional and asserts RESET as long as VCC stays within 1.0 V to 5.5 V.
Is ADM810TARTZ-REEL RoHS compliant?
Yes, ADM810TARTZ-REEL is RoHS compliant, as indicated by the "Z" suffix in the part number per Analog Devices' ordering guide. It meets EU Directive 2011/65/EU requirements and contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
What package type and dimensions does ADM810TARTZ-REEL use?
ADM810TARTZ-REEL uses the 3-lead SOT-23 (RT-3) package: 2.90 mm × 1.30 mm footprint, 1.02 mm maximum height, and 0.95 mm seating plane height. It complies with JEDEC TO-236-AB standards and is compatible with automated assembly processes including reflow soldering.
