Product details
Overview
ADM810RAKS-REEL from Analog Devices is a microprocessor supervisory circuit in 3-lead SC70 package, providing active-high push-pull reset assertion with 2.63 V threshold, 240 ms typical timeout, and operation down to 1 V VCC. It monitors supply voltage in embedded controllers and ensures reliable power-on reset for industrial microprocessor systems.
For engineers reviewing the ADM810RAKS-REEL datasheet, ADM810RAKS-REEL pinout, ADM810RAKS-REEL application, or ADM810RAKS-REEL equivalent, key selection factors include reset polarity (active-high), SC70 package compatibility, 2.63 V threshold accuracy over −40°C to +125°C, and low 17 μA supply current for battery-sensitive designs.
Technical Context
The ADM810RAKS-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reference circuit maintains ±1.5% threshold accuracy across temperature, enabling stable reset assertion during brownout conditions down to VCC = 1 V.
Unlike open-drain variants (e.g., ADM803), the ADM810RAKS-REEL 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 and simplifying interface with CMOS microcontrollers requiring active-high reset inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63 V (typical), ±1.5% over −40°C to +125°C - ensures accurate detection of 2.7 V nominal supply collapse |
| Reset Timeout | 240 ms (typical) after VCC rises above threshold - guarantees sufficient microprocessor initialization time |
| Supply Current | 17 μA (typical at VCC < 3.6 V, −40°C to +85°C) - enables use in always-on, low-power monitoring circuits |
| VCC Operating Range | 1.0 V to 5.5 V - supports reset assertion even during deep brownout or partial power loss |
| Output Type | Active-high push-pull - directly drives CMOS reset inputs without external components |
| Temperature Range | −40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Package | 3-lead SC70 (KS-3) - 2.0 mm × 2.1 mm footprint, compatible with high-density PCB layouts |
Pinout & Package
ADM810RAKS-REEL uses a 3-lead SC70 (KS-3) package with exposed pad not electrically connected. Pin 1 is VCC, Pin 2 is RESET (active-high output), and Pin 3 is GND - matching JEDEC SC70 outline and enabling drop-in replacement for other SC70 supervisory ICs with identical pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input - must be connected to the voltage rail being supervised (e.g., 2.7 V system rail) |
| 2 | RESET | Active-high push-pull output - asserts logic high during reset; sinks current when deasserted |
| 3 | GND | Ground reference - requires low-impedance connection to system ground plane for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects transients ≤100 μs duration at VTH – VCC ≥ 100 mV - prevents false resets from supply noise |
| Precision threshold tolerance | ±1.5% over full temperature range - eliminates need for external calibration in production test |
| Low-voltage operation | Valid reset assertion down to VCC = 1.0 V - ensures fail-safe behavior during severe brownout |
| Push-pull output drive | Sources 150 μA at 1.8 V < VCC < VTH min - directly interfaces to standard CMOS reset inputs |
| SC70 footprint compatibility | 2.0 mm × 2.1 mm body, 0.65 mm lead pitch - fits same land pattern as ADM809/ADM803 SC70 variants |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809RAKSZ-REEL7 | Same 2.63 V threshold, −40°C to +125°C, but active-low push-pull output | Requires invert logic at MCU reset input or redesign of reset signal path | Select only if existing design uses active-low reset architecture and board layout cannot accommodate signal inversion |
| MAX6326R26T | 2.63 V threshold, SOT-23-3 package, 140 ms min timeout (vs. 240 ms typ), 2.5 μA max supply current | Shorter minimum timeout may risk incomplete MCU initialization; lower current suits ultra-low-power sleep modes | Prefer when minimizing standby current is critical and 140 ms reset duration meets MCU spec |
Compared with ADM809RAKSZ-REEL7, ADM810RAKS-REEL avoids external inversion hardware; compared with MAX6326R26T, it provides longer guaranteed reset hold time at the cost of slightly higher quiescent current - favoring reliability-critical applications over extreme energy constraints.

FAQ
What is the reset output polarity of the ADM810RAKS-REEL?
The ADM810RAKS-REEL features an active-high push-pull RESET output. It asserts logic high while VCC is below the 2.63 V threshold and remains high for 240 ms (typical) after VCC rises above threshold. This eliminates need for external level-shifting or inversion when interfacing with MCUs requiring active-high reset signals, unlike the active-low ADM809RAKSZ-REEL7.
Does the ADM810RAKS-REEL require an external pull-up resistor?
No, the ADM810RAKS-REEL does not require an external pull-up resistor because it uses a push-pull output stage. Its RESET pin actively drives both high and low states, unlike open-drain variants such as the ADM803. This simplifies PCB layout and reduces BOM count in designs using the ADM810RAKS-REEL.
What is the minimum VCC voltage at which the ADM810RAKS-REEL guarantees reset assertion?
The ADM810RAKS-REEL guarantees valid reset assertion down to VCC = 1.0 V, as specified in its absolute maximum ratings and functional description. Below this, the internal circuitry may not operate reliably. This capability ensures fail-safe behavior during severe brownout conditions where other supervisory ICs might release reset prematurely.
Can the ADM810RAKS-REEL replace the ADM809RAKSZ-REEL7 in an existing design?
The ADM810RAKS-REEL can replace the ADM809RAKSZ-REEL7 only if the target MCU accepts active-high reset input. Both share identical SC70 package, pinout, and 2.63 V threshold, but ADM809RAKSZ-REEL7 outputs active-low RESET. Swapping without modifying reset signal routing will invert system behavior - verify MCU reset polarity before substitution.
What is the temperature coefficient of the reset threshold for the ADM810RAKS-REEL?
The ADM810RAKS-REEL has a reset threshold temperature coefficient of 30 ppm/°C, as stated in the specifications table. This low drift ensures threshold stability across −40°C to +125°C, supporting consistent brownout detection in automotive and industrial applications where ambient temperature varies widely.
