Product details
Overview
ADM810TAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 3-lead SC70 package, providing active-high push-pull reset output with 3.08 V threshold, 140–460 ms reset timeout, and operation down to 1.0 V VCC. It monitors supply voltage in embedded controllers and ensures reliable power-on reset for industrial microprocessor systems.
For engineers reviewing the ADM810TAKSZ-REEL7 datasheet, ADM810TAKSZ-REEL7 pinout, ADM810TAKSZ-REEL7 application, or ADM810TAKSZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), SC70 package compatibility, −40°C to +125°C temperature range, low 17 μA supply current, and precise 3.08 V threshold tolerance across full operating temperature.
Technical Context
The ADM810TAKSZ-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms (typical) reset timer. Its reset assertion remains valid even as VCC drops to 1.0 V, enabling robust brownout detection in wide-input-voltage systems.
Unlike open-drain variants (e.g., ADM803), this device features a push-pull RESET output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min), eliminating need for external pull-up resistors. The 3.08 V threshold is calibrated for 3 V nominal supply monitoring with ±0.15 V tolerance over −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08 V (nominal); monitors 3 V rail with ±0.15 V tolerance over full −40°C to +125°C range |
| Reset Polarity | Active-high push-pull output; asserts high during power-up/brownout, deasserts low when stable |
| Reset Timeout | 140–460 ms (min–max) after VCC rises above threshold; ensures microprocessor initialization completes |
| Supply Current | 17 μA (typical); enables use in battery-powered and ultra-low-power embedded systems |

| Temperature Range | −40°C to +125°C; qualified for automotive under-hood and industrial control environments |
Pinout & Package
ADM810TAKSZ-REEL7 uses a 3-lead SC70 (KS-3) package with exposed pad not electrically connected. Pin 1 = VCC, Pin 2 = RESET (active-high push-pull), Pin 3 = GND - confirmed per Figure 4 and Table 4 of Rev. I datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input; powers internal circuitry and defines reset threshold reference |
| 2 | RESET | Active-high push-pull output; drives high during reset condition, low when VCC stable ≥3.08 V |
| 3 | GND | Ground reference for comparator and output stage; must be low-impedance return path |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects fast transients up to 100 mV overdrive without false reset assertion |
| Precision threshold accuracy | ±1.5% typical deviation at 25°C; ±3.5% max over −40°C to +125°C for 3.08 V option |
| Low-VCC reset operation | Valid RESET output asserted down to VCC = 1.0 V, enabling early-fail detection |
| Push-pull output architecture | Eliminates external pull-up resistor; reduces BOM count and layout complexity |
| Ultra-low quiescent current | 17 μA typical at VCC < 3.6 V; extends battery life in portable instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM810TARTZ-REEL7 | SOT-23-3 package (RT-3); identical electrical specs, 2.90 mm × 1.30 mm footprint vs. SC70's 2.00 mm × 2.10 mm | Better thermal dissipation (θJA = 270°C/W vs. 146°C/W) but larger board area; preferred for high-temperature reflow or manual assembly | Select when SOT-23 handling infrastructure exists or thermal margin >10°C required at 125°C ambient |
| MAX810TTRG+T | 3.00 V threshold (±2.5%), 140 ms min timeout, 2.5 μA max supply current; SOT-23-3 only | Lower threshold tolerance and no −40°C to +125°C grade; rated only to +85°C; requires external capacitor for timeout tuning | Choose only for cost-sensitive commercial-grade designs where extended temperature range and tighter threshold are non-critical |
Compared with ADM810TAKSZ-REEL7, ADM810TARTZ-REEL7 offers identical functionality in a thermally robust but larger SOT-23 package, while MAX810TTRG+T trades precision and temperature range for lower quiescent current and cost-making it suitable only for non-automotive, non-industrial applications.

FAQ
What is the exact reset threshold voltage of ADM810TAKSZ-REEL7 and how does it vary with temperature?
The ADM810TAKSZ-REEL7 has a nominal reset threshold of 3.08 V at 25°C, with guaranteed range of 3.00 V to 3.15 V at −40°C to +85°C and 2.95 V to 3.21 V at −40°C to +125°C per Table 1. This 3.08 V value is selected to monitor 3 V nominal supplies while maintaining adequate noise margin against ripple and load transients.
Does ADM810TAKSZ-REEL7 require an external pull-up resistor on the RESET pin?
No, ADM810TAKSZ-REEL7 features a push-pull RESET output and does not require an external pull-up resistor. Its active-high output drives high during reset and pulls low when deasserted, unlike the open-drain ADM803 variant which mandates external pull-up.
Can ADM810TAKSZ-REEL7 operate reliably when VCC drops below 2.0 V?
Yes, ADM810TAKSZ-REEL7 guarantees valid RESET assertion down to VCC = 1.0 V, as specified in the Absolute Maximum Ratings and General Description sections. This enables early brownout detection before critical logic levels collapse, ensuring safe system shutdown.
What is the package type and footprint of ADM810TAKSZ-REEL7?
ADM810TAKSZ-REEL7 uses the 3-lead SC70 (KS-3) package with dimensions 2.00 mm × 2.10 mm × 0.90 mm (max height), per Figure 15 in the datasheet. It is RoHS-compliant (indicated by 'Z' suffix) and marked with 'M4V' top-side branding.
How does the reset timeout behavior of ADM810TAKSZ-REEL7 change across temperature?
ADM810TAKSZ-REEL7 provides 140–460 ms reset timeout at −40°C to +85°C and 100–840 ms at +85°C to +125°C, per Table 1. The variation ensures sufficient hold time for microprocessor initialization across all operating conditions while avoiding excessive delays in high-temperature environments.
