Product details
Overview
ADM810TAKS-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 V VCC. It provides 240 ms minimum power-on reset timeout, consumes 17 μA typical supply current, and is qualified for −40°C to +125°C industrial/automotive environments. Used in embedded controllers to ensure reliable boot sequencing under brownout conditions.
For engineers reviewing the ADM810TAKS-REEL datasheet, ADM810TAKS-REEL pinout, ADM810TAKS-REEL application, or ADM810TAKS-REEL equivalent, key selection criteria include reset polarity (active-high), SC70-3 package compatibility, temperature-rated threshold accuracy (±2.5% over −40°C to +125°C), and low-power operation in battery-backed systems.
Technical Context
The ADM810TAKS-REEL implements a precision bandgap voltage reference and comparator to monitor VCC against a fixed 3.08 V threshold. Its internal timer asserts RESET for 240 ms (typical) after VCC rises above threshold, ensuring stable microprocessor initialization.
It features built-in glitch immunity against fast transients on VCC and maintains valid RESET assertion down to VCC = 1 V. The push-pull output drives logic-high without external pull-up, supporting direct interface to CMOS inputs across 1.8–5.5 V supply ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08 V ±2.5% over −40°C to +125°C - ensures reliable detection of 3.3 V rail collapse before microprocessor malfunction. |
| Reset Timeout | 240 ms typical power-on delay - holds processor in reset until power and clock stabilize post-power-up. |
| Supply Current | 17 μA typical at VCC < 3.6 V - enables use in always-on, battery-powered monitoring circuits. |
| VCC Operating Range | 1.0 V to 5.5 V - supports reset assertion during deep brownout and compatibility with 1.8 V, 3.3 V, and 5 V systems. |
| Output Type | Push-pull active-high - eliminates need for external pull-up resistor and simplifies PCB layout. |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive and industrial control applications. |
Pinout & Package
ADM810TAKS-REEL is housed in a 3-lead SC70 (KS-3) package, measuring 2.00 mm × 1.25 mm × 0.9 mm, with gull-wing leads and JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input - connects directly to the 3.3 V rail being supervised. |
| 2 | RESET | Active-high push-pull output - drives high when VCC ≥ 3.08 V and remains high for 240 ms after threshold crossing. |
| 3 | GND | Ground reference - must be connected to system ground plane for accurate threshold sensing and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects transients ≤100 µs duration at 100 mV overdrive - prevents false resets from switching noise or ESD. |
| Low-VCC reset operation | Asserts RESET down to VCC = 1.0 V - guarantees fail-safe behavior during severe undervoltage events. |
| Precision threshold tolerance | ±2.5% over full temperature range - eliminates need for external trimming in production calibration. |
| SC70-3 footprint | 0.65 mm lead pitch, 2.0 mm × 1.25 mm body - enables high-density placement in space-constrained IoT and automotive modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G33DBVR | 3.3 V threshold, 200 ms reset timeout, 1.5 μA IQ, SOT-23-6 package | Requires external capacitor for timeout adjustment; lower IQ but larger footprint and different pinout | Select when ultra-low power (<2 μA) is critical and board area permits SOT-23-6 layout. |
| MAX809TRD3T | 3.08 V threshold, 240 ms timeout, open-drain output, SOT-23-3 package | Active-low output requires pull-up; identical threshold and timing but incompatible logic polarity | Choose only if system design already uses active-low reset architecture and can accommodate external pull-up. |

FAQ
What is the reset threshold voltage of the ADM810TAKS-REEL?
The ADM810TAKS-REEL has a nominal reset threshold voltage of 3.08 V, with guaranteed tolerance of ±2.5% over the full operating temperature range of −40°C to +125°C. This value is laser-trimmed during manufacturing and specified in Table 3 of the ADM803/ADM809/ADM810 datasheet Rev. I. The threshold remains stable across VCC from 1.0 V to 5.5 V, making ADM810TAKS-REEL suitable for monitoring 3.3 V rails in automotive and industrial applications.
Does the ADM810TAKS-REEL have an active-high or active-low reset output?
The ADM810TAKS-REEL features an active-high push-pull RESET output. When VCC falls below 3.08 V, RESET goes low; when VCC rises above threshold, RESET transitions high and remains high for 240 ms (typical) to ensure proper microprocessor initialization. This differs from the ADM809 (also push-pull but active-low) and ADM803 (open-drain active-low). The ADM810TAKS-REEL requires no external pull-up resistor due to its integrated push-pull driver.
What package type is used for the ADM810TAKS-REEL?
The ADM810TAKS-REEL is supplied in a 3-lead SC70 package (JEDEC designation KS-3), with dimensions of 2.00 mm × 1.25 mm × 0.9 mm and 0.65 mm lead pitch. This compact footprint is smaller than the alternative SOT-23-3 (RT-3) variant and enables high-density placement in space-constrained designs such as portable medical devices and automotive sensors. Pin 1 is VCC, Pin 2 is RESET, and Pin 3 is GND per Figure 4 and Table 4 of the datasheet.
What is the minimum VCC voltage at which the ADM810TAKS-REEL continues to assert reset?
The ADM810TAKS-REEL maintains valid RESET assertion down to VCC = 1.0 V, as specified in the "VCC OPERATING VOLTAGE RANGE" row of Table 1 (Rev. I, Page 3). Below this level, the internal circuitry ceases to function reliably. This capability ensures fail-safe behavior during deep brownout conditions - for example, when a 3.3 V LDO collapses to 1.2 V during battery depletion. The ADM810TAKS-REEL's ability to operate at 1 V distinguishes it from many competing supervisors limited to 1.8 V minimum.
How does the ADM810TAKS-REEL handle fast transients on the VCC line?
The ADM810TAKS-REEL incorporates a glitch-immune reset comparator that rejects transients ≤100 µs in duration when the overdrive (VTH – VCC) is ≥100 mV, as shown in Figure 11 of the datasheet. This design prevents false resets caused by switching noise, ESD coupling, or load-dump events. The immunity is achieved through internal filtering and hysteresis, not external components - a key advantage of ADM810TAKS-REEL in electrically noisy environments like motor drives or automotive power distribution systems.
