Product details
Overview
ADM810TAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 3.08 V reset threshold, −40°C to +125°C operating temperature range, and 17 μA supply current. It monitors VCC in embedded microcontroller systems and asserts reset during power-up, brownout, or power-down down to 1 V VCC.
For engineers reviewing the ADM810TAKS-REEL7 datasheet, ADM810TAKS-REEL7 pinout, ADM810TAKS-REEL7 application, or ADM810TAKS-REEL7 equivalent, key selection criteria include reset polarity (active-high), SC70-3 package compatibility, guaranteed 140–460 ms reset timeout, low-power operation, and industrial temperature support.
Technical Context
The ADM810TAKS-REEL7 implements a precision voltage comparator with built-in glitch immunity and an internal 240 ms (typical) power-on reset timer. Its reset assertion remains valid even as VCC drops to 1.0 V, ensuring reliable microprocessor initialization under marginal supply conditions.
It features a fixed 3.08 V reset threshold (±3% over −40°C to +125°C), operates from 1.2 V to 5.5 V VCC, and delivers push-pull logic-level RESET output without requiring external pull-up components-unlike open-drain variants in the same family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08 V ±3% over −40°C to +125°C - ensures stable reset assertion for 3.3 V supply rails with margin against noise and drift |
| Supply Current | 17 μA typical at VCC < 3.6 V - enables use in battery-powered and ultra-low-power embedded systems |
| VCC Operating Range | 1.2 V to 5.5 V - supports operation during deep brownout and allows monitoring of diverse supply domains |
| Reset Timeout | 140–460 ms (−40°C to +85°C) - guarantees sufficient hold time for microprocessor core and peripheral stabilization |
| RESET Output Type | Push-pull active-high - eliminates need for external pull-up resistor and provides clean CMOS-compatible logic levels |
| Minimum VCC for RESET | 1.0 V - maintains functional reset assertion even during severe undervoltage events |
| Temperature Range | −40°C to +125°C - qualified for automotive under-hood, industrial control, and harsh-environment applications |
Pinout & Package
ADM810TAKS-REEL7 is housed in a 3-lead SC70 (KS-3) package, measuring 2.00 mm × 1.25 mm × 0.95 mm, with gull-wing leads and JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input - connects directly to the voltage rail being supervised (e.g., 3.3 V microcontroller VDD) |
| 2 | RESET | Active-high push-pull output - drives high during normal operation; pulls low for reset duration; no external pull-up required |
| 3 | GND | Ground reference - must be connected to system ground plane with low-impedance path for accurate threshold sensing |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects fast transients up to 100 mV overdrive for ≤400 µs - prevents spurious resets from supply noise or ESD coupling |
| Precision voltage reference | 30 ppm/°C tempco - maintains tight reset threshold stability across full industrial temperature range |
| Low-voltage reset operation | Functional down to 1.0 V VCC - ensures reset remains asserted through deep brownout until safe recovery |
| Fixed 240 ms (typ) power-on delay | Internally timed - eliminates need for external RC network and improves BOM simplicity and reliability |
| RoHS-compliant SC70-3 package | KS-3 outline with 0.65 mm lead pitch - enables high-density PCB layouts and automated assembly compatibility |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
Use Scenario: Monitors 3.3 V microcontroller supply in programmable logic controllers exposed to wide ambient temperature swings and electrical noise. IC Role / Device Role / Timing Role: Supervisory circuit providing active-high reset signal synchronized to VCC ramp-up and brownout detection. Use Value: Guarantees deterministic microcontroller startup and fault recovery at −40°C to +125°C with 3.08 V threshold matched to 3.3 V rail tolerance. | Use Scenario: Embedded in body control units where 3.3 V domain powers CAN transceivers and sensor interfaces. IC Role / Device Role / Timing Role: Voltage monitor asserting active-high RESET to hold MCU in reset until 3.3 V rail stabilizes post-battery crank. Use Value: Push-pull output drives CAN controller reset pin directly; 17 μA quiescent current minimizes standby drain on vehicle battery. |
| Medical Infusion Pump | Smart Energy Meter |
Use Scenario: Ensures fail-safe restart of safety-critical ARM Cortex-M based pump controller after power interruption. IC Role / Device Role / Timing Role: Primary reset supervisor with guaranteed 140 ms minimum timeout and 1 V VCC operation for robust brownout response. Use Value: Active-high RESET matches most modern MCU reset inputs; SC70-3 footprint saves space in compact, sealed enclosure designs. | Use Scenario: Supervises 3.3 V supply powering metrology ADC and RF communication IC in utility-grade meters. IC Role / Device Role / Timing Role: Precision voltage monitor detecting undervoltage on isolated 3.3 V rail generated from AC line or backup battery. Use Value: 3.08 V threshold provides optimal margin above 3.3 V nominal (−5% tolerance = 3.135 V), preventing premature reset assertion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809TAKSZ-REEL7 | Same 3.08 V threshold, −40°C to +125°C, but active-low push-pull RESET output | Requires MCU with active-low reset input; incompatible with active-high-only reset pins | Select when interfacing to legacy MCUs requiring active-low reset assertion |
| TPS3123QDBVRQ1 | 3.08 V threshold, AEC-Q100 Grade 1, 2.7–6 V VCC range, 1.5 μA IQ, but only available in SOT-23-3 | Automotive-qualified with lower quiescent current; lacks SC70 option and has different pinout (GND/RESET/VCC vs. VCC/RESET/GND) | Choose for automotive production requiring AEC-Q100 qualification and lowest possible supply current |
Compared with ADM809TAKSZ-REEL7, ADM810TAKS-REEL7 avoids level-shifting or inverter logic by delivering native active-high RESET; versus TPS3123QDBVRQ1, it offers SC70 packaging for space-constrained designs but lacks AEC-Q100 certification and higher VCC min specification.

FAQ
What is the reset polarity of ADM810TAKS-REEL7?
The ADM810TAKS-REEL7 provides an active-high RESET output: RESET remains high while VCC is below the 3.08 V threshold and stays high for 240 ms (typical) after VCC rises above threshold. This differs from ADM809 variants, which assert active-low RESET. The push-pull structure eliminates need for external pull-up resistors.
Does ADM810TAKS-REEL7 support operation below 2.0 V VCC?
Yes, ADM810TAKS-REEL7 remains functional down to 1.0 V VCC, maintaining valid RESET assertion during deep brownout conditions. Its reset comparator and internal timer operate reliably at this level, enabling robust fault recovery in systems with weak or decaying supplies - a key capability confirmed in the Absolute Maximum Ratings and General Description sections of the datasheet.
What package type is used for ADM810TAKS-REEL7?
ADM810TAKS-REEL7 uses the 3-lead SC70 (KS-3) package: 2.00 mm × 1.25 mm × 0.95 mm body size with gull-wing leads and 0.65 mm pitch. This RoHS-compliant outline is distinct from the SOT-23 variant (RT-3) used in other members of the ADM810 family and is optimized for high-density PCB layouts.
How does the reset timeout vary with temperature for ADM810TAKS-REEL7?
ADM810TAKS-REEL7 specifies a reset active timeout period of 140–460 ms over −40°C to +85°C, and 100–840 ms over +85°C to +125°C. This variation is inherent to the internal RC timing circuit and is fully characterized in Table 1 of the datasheet; design margins should accommodate the full specified range rather than relying solely on the 240 ms typical value.
Can ADM810TAKS-REEL7 replace ADM803TAKS-REEL7 in an existing design?
No, ADM810TAKS-REEL7 cannot directly replace ADM803TAKS-REEL7 due to fundamental differences: ADM803 has open-drain active-low RESET requiring an external pull-up, while ADM810 has push-pull active-high RESET. Pinout is also inverted (VCC/RESET/GND vs. GND/RESET/VCC). Board-level changes would be required to accommodate polarity, drive strength, and pin mapping differences.
