Product details
Overview
ADM810SARTZ-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 2.93 V reset threshold, −40°C to +125°C operating temperature range, and 17 μA supply current. It monitors VCC in embedded systems and asserts reset for 240 ms (typical) during power-up, brownout, or power-down conditions down to 1 V VCC.
For engineers reviewing the ADM810SARTZ-REEL7 datasheet, ADM810SARTZ-REEL7 pinout, ADM810SARTZ-REEL7 application, or ADM810SARTZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), SOT-23-3 package compatibility, guaranteed operation at 1 V VCC, 240 ms timeout stability over temperature, and precision 2.93 V threshold tolerance (±30 mV at −40°C to +85°C).
Technical Context
The ADM810SARTZ-REEL7 implements a precision voltage comparator with built-in glitch immunity to reject fast transients on VCC, and an internal 240 ms power-on reset timer. Its reset assertion remains valid even as VCC drops to 1 V, ensuring reliable microprocessor initialization under marginal supply conditions.
Unlike open-drain variants (e.g., ADM803), the ADM810SARTZ-REEL7 uses a push-pull output stage capable of sourcing 150 μA at 1.8 V < VCC < VTH min, eliminating need for external pull-up resistors. Its reset threshold exhibits only 30 ppm/°C temperature coefficient, enabling stable performance across industrial and automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93 V ±30 mV (−40°C to +85°C); ensures accurate detection of 3.3 V rail undervoltage before system instability. |
| Reset Timeout | 240 ms typical; holds microprocessor in reset long enough for clock stabilization and memory initialization. |
| 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; guarantees functional reset assertion even during deep brownout or partial power loss. |
| Output Type | Push-pull active-high RESET; drives CMOS inputs directly without external components, reducing BOM count. |
| Temp Range | −40°C to +125°C; qualified for under-hood automotive, industrial control, and harsh-environment applications. |
| Reset Propagation Delay | 20 μs max from VCC crossing threshold; provides fast response to supply faults without false triggering. |
Pinout & Package
ADM810SARTZ-REEL7 is housed in a 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB standard, with 1.30 mm × 2.90 mm footprint and 0.95 mm height. Pin 1 = VCC, Pin 2 = RESET (active-high push-pull), Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Supply Input | Monitored voltage rail; device operates and asserts reset based on this input, functional down to 1 V. |
| 2 (RESET) | Active-High Push-Pull Output | Drives high during normal operation; pulls low for 240 ms after power-up or brownout; no external pull-up required. |
| 3 (GND) | Ground Reference | Common return path for internal comparator and output stage; must be low-impedance for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects transients ≤100 µs duration at VTH – VCC ≥100 mV, preventing spurious resets from supply noise. |
| Precision threshold tolerance | ±30 mV over −40°C to +85°C ensures consistent reset point across thermal cycling in industrial environments. |
| Low-voltage operation | Functional reset assertion at VCC = 1 V enables robust fail-safe behavior during severe brownout events. |
| Temperature-stable timing | 240 ms reset timeout varies less than ±5% from −40°C to +125°C, guaranteeing deterministic boot sequencing. |
| RoHS-compliant packaging | SOT-23-3 (RT-3) with lead-free finish and halogen-free molding compound meets global environmental regulations. |
Applications
| Industrial PLC Control | Automotive Body Controller |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809SARTZ-REEL7 | Same 2.93 V threshold, SOT-23-3 package, but active-low push-pull RESET output. | Requires logic inversion or MCU pin reassignment for active-high reset interface. | Select when existing design uses active-low reset architecture or shares PCB layout with ADM809 family. |
| TPS3808G12DBVR | 2.93 V threshold, SOT-23-6 package, 35 μA supply current, 200 ms reset timeout, adjustable delay via capacitor. | Larger footprint, higher quiescent current, longer timeout; lacks 1 V VCC operation capability. | Choose if adjustable timeout or enhanced ESD protection (4 kV HBM) is prioritized over ultra-low power and deep-brownout resilience. |
Compared with ADM809SARTZ-REEL7, ADM810SARTZ-REEL7 eliminates need for external inverters in active-high systems; compared with TPS3808G12DBVR, it delivers 2.4× lower supply current and guaranteed function at 1 V VCC-critical for energy harvesting or backup battery designs.

FAQ
What is the reset output polarity of ADM810SARTZ-REEL7?
The ADM810SARTZ-REEL7 features an active-high push-pull RESET output: RESET remains high while VCC is below the 2.93 V threshold and stays high for 240 ms (typical) after VCC rises above threshold. This eliminates external level-shifting components required by active-low alternatives like ADM809SARTZ-REEL7.
Does ADM810SARTZ-REEL7 operate reliably at low VCC voltages?
Yes. ADM810SARTZ-REEL7 guarantees functional reset assertion down to VCC = 1.0 V, enabling fail-safe behavior during deep brownout conditions. Its internal comparator and timer remain operational across the full 1.0 V to 5.5 V supply range, unlike many supervisors that cease functioning below 2.0 V.
What package type and dimensions does ADM810SARTZ-REEL7 use?
ADM810SARTZ-REEL7 uses a 3-lead SOT-23 (RT-3) package compliant with JEDEC TO-236-AB standards. Its footprint measures 1.30 mm × 2.90 mm with 0.95 mm maximum height, and pin pitch is 0.65 mm. This compact size supports high-density PCB layouts in space-constrained applications.
How does ADM810SARTZ-REEL7 handle supply voltage transients?
ADM810SARTZ-REEL7 incorporates a glitch-immune reset comparator that rejects transients ≤100 µs duration when VTH – VCC ≥100 mV. This prevents false resets caused by switching noise, load dumps, or ESD-induced supply disturbances-verified in Figure 11 of the datasheet.
Is ADM810SARTZ-REEL7 RoHS compliant and lead-free?
Yes. ADM810SARTZ-REEL7 is a RoHS-compliant part (denoted by "Z" suffix) with lead-free finish and halogen-free molding compound. It meets EU Directive 2011/65/EU and is suitable for environmentally regulated markets including automotive and medical devices.
