Product details
Overview
ADM810ZART-REEL from Analog Devices is a microprocessor supervisory circuit with active-high push-pull RESET output, 2.32 V reset threshold, and operation down to 1.0 V VCC. It provides 240 ms typical power-on reset timeout, consumes 17 μA supply current, and is qualified for −40°C to +125°C industrial temperature range. It monitors supply voltage in embedded controllers requiring reliable brownout detection.
For engineers reviewing the ADM810ZART-REEL datasheet, ADM810ZART-REEL pinout, ADM810ZART-REEL application, or ADM810ZART-REEL equivalent, key selection criteria include reset polarity (active-high), SOT-23-3 package compatibility, low-voltage operation (1.0 V min), precision 2.32 V threshold tolerance (±0.07 V at 25°C), and guaranteed reset assertion during power-down transitions.
Technical Context
The ADM810ZART-REEL integrates a precision bandgap voltage reference and comparator with built-in glitch immunity to reject fast transients on VCC up to 100 mV overdrive. Its internal timer ensures reset remains asserted for 240 ms (typical) after VCC rises above 2.32 V, preventing premature microprocessor release.
It features push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min) and sinking 1.2 mA at VCC = VTH(min), eliminating need for external pull-up resistors. The device operates across full VCC range (1.0 V to 5.5 V) while maintaining reset functionality down to 1 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.32 V ±0.07 V at 25°C; enables precise monitoring of 2.5 V rail with margin for dropout. |
| Reset Polarity | Active-high push-pull output; directly interfaces to microprocessor nRESET pins without pull-up. |
| Reset Timeout | 240 ms typical power-on delay; holds processor in reset until supply stabilizes post-power-up. |
| Supply Current | 17 μA typical at VCC < 3.6 V; supports battery-backed and ultra-low-power portable systems. |
| VCC Operating Range | 1.0 V to 5.5 V; ensures valid reset assertion even during deep brownout conditions. |
| Temperature Range | −40°C to +125°C; suitable for under-hood automotive and industrial control environments. |
| Output Drive | Sinks 1.2 mA / sources 150 μA; drives standard CMOS inputs without external components. |
Pinout & Package
ADM810ZART-REEL uses a 3-lead SOT-23 (RT-3) package with 1.3 mm × 2.9 mm footprint and 0.95 mm height, compliant with JEDEC TO-236-AB standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground reference | 0 V return path for internal reference and output stage; must be low-impedance connection. |
| 2 (RESET) | Active-high push-pull output | Drives high when VCC ≥ 2.32 V (after timeout); drives low when VCC < 2.32 V or during reset period. |
| 3 (VCC) | Monitored supply input | Input voltage source being supervised; powers internal circuitry and defines reset assertion boundary. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 2.32 V threshold | ±2.7% tolerance over −40°C to +125°C; eliminates need for external resistor networks in 2.5 V system monitoring. |
| 17 μA quiescent current | Enables >10-year battery life in coin-cell-powered IoT sensors with periodic wake-up cycles. |
| Glitch-immune comparator | Rejects transients ≤100 μs duration at 100 mV overdrive; prevents false resets from switching noise or ESD. |
| 1.0 V minimum VCC operation | Asserts reset down to 1.0 V; guarantees safe shutdown before logic corruption occurs in failing supplies. |
| Push-pull output | No external pull-up required; reduces BOM count and PCB area vs. open-drain alternatives like ADM803. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809ZTRD1+ | 2.32 V threshold, active-low open-drain output, 1.2 μA max supply current, SOT-23-3 package. | Requires external pull-up resistor; incompatible with microprocessors expecting active-high reset. | Select only if system design accommodates active-low signaling and ultra-low current is critical. |
| TPS3808G12DBVR | 1.225 V threshold (not 2.32 V), adjustable via external resistor, 1.1 μA supply current, SOT-23-6 package. | 6-pin package increases PCB area; threshold mismatch requires redesign of voltage divider network. | Choose only when programmable threshold and lower current outweigh fixed-threshold simplicity and footprint constraints. |

FAQ
What is the reset threshold voltage of ADM810ZART-REEL and its tolerance over temperature?
The ADM810ZART-REEL has a nominal reset threshold of 2.32 V at 25°C, with tolerance of ±0.07 V (±3%) at 25°C and ±0.13 V (±5.6%) over −40°C to +125°C. This precision enables accurate supervision of 2.5 V rails while accommodating worst-case voltage droop and temperature drift without false triggering.
Does ADM810ZART-REEL require an external pull-up resistor on the RESET pin?
No, ADM810ZART-REEL does not require an external pull-up resistor because it features a push-pull RESET output. Unlike open-drain variants such as ADM803, the ADM810ZART-REEL actively drives both high and low states, simplifying interface design and reducing component count in systems using active-high reset inputs.
What is the minimum VCC voltage at which ADM810ZART-REEL continues to assert RESET?
ADM810ZART-REEL continues to assert RESET (drives low) down to VCC = 1.0 V, as specified in the Absolute Maximum Ratings table and confirmed in the General Description. This ensures robust brownout detection even during severe supply collapse, preventing microprocessor operation outside its valid voltage range.
How long does the RESET signal remain active after power-up for ADM810ZART-REEL?
The ADM810ZART-REEL holds RESET active (low) for a minimum of 140 ms and typical 240 ms after VCC rises above the 2.32 V threshold. This timeout is internally generated and temperature-compensated, ensuring consistent reset duration across −40°C to +125°C without external timing components.
Is ADM810ZART-REEL RoHS compliant and what package does it use?
Yes, ADM810ZART-REEL is RoHS compliant (denoted by "Z" in the part number) and uses a 3-lead SOT-23 (RT-3) package with JEDEC TO-236-AB footprint. Its dimensions are 2.90 mm × 1.30 mm × 1.02 mm, making it suitable for high-density PCB layouts in compact industrial and automotive modules.
