Product details
Overview
ADM810SAKS-REEL from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 2.93 V reset threshold, and operation down to 1 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/automotive environments. It monitors 3 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810SAKS-REEL datasheet, ADM810SAKS-REEL pinout, ADM810SAKS-REEL application, or ADM810SAKS-REEL equivalent, key selection criteria include reset polarity (active-high), SC70 package compatibility, temperature-rated threshold accuracy, and low-voltage reset assertion capability.
Technical Context
The ADM810SAKS-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reset threshold is trimmed to 2.93 V at 25°C with ±15 mV tolerance over −40°C to +85°C and ±22 mV over −40°C to +125°C.
It features push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min), sinking 1.2 mA at VTH(min), and operating with VCC as low as 1.0 V while maintaining valid RESET assertion - enabling reliable brownout detection in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93 V (typical at 25°C); monitors 3 V nominal supplies with ±15 mV accuracy over industrial temp range |
| Reset Polarity | Active-high; asserts high during power-up/brownout and holds for 240 ms after VCC exceeds threshold |
| Supply Current | 17 μA (typical); enables use in always-on, low-power embedded monitoring applications |
| VCC Operating Range | 1.0 V to 5.5 V; supports reset assertion even during deep brownout or battery depletion |
| Reset Timeout | 140–460 ms (min/typ/max); ensures microprocessor stabilization before release from reset state |
| Temperature Range | −40°C to +125°C; qualified for under-hood automotive and industrial control environments |
| Output Type | Push-pull; eliminates need for external pull-up resistor and simplifies interface to CMOS inputs |
Pinout & Package
ADM810SAKS-REEL is housed in a 3-lead SC70 (KS-3) package, measuring 2.00 mm × 2.10 mm × 0.95 mm, with gull-wing leads and JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input; must be connected to the 3 V rail being supervised |
| 2 | RESET | Active-high push-pull output; drives high during reset, low when deasserted - directly interfaces to µP reset pin |
| 3 | GND | Ground reference for comparator and output stage; requires low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | 2.93 V ±15 mV over −40°C to +85°C ensures accurate 3 V supply monitoring without external calibration |
| Low-voltage reset assertion | Operates down to 1.0 V VCC, enabling fail-safe reset during battery sag or power collapse |
| Glitch-immune comparator | Built-in immunity to fast transients on VCC prevents spurious resets from noise or switching spikes |
| Fixed 240 ms timeout | Internally timed reset hold-off guarantees sufficient microprocessor initialization time after power stabilization |
| Ultra-low quiescent current | 17 μA typical supply draw minimizes impact on battery life in portable or energy-harvesting systems |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
Use Scenario: Monitors 3 V auxiliary supply powering MCU and CAN transceiver in programmable logic controller cabinets exposed to wide ambient temperatures. IC Role / Device Role / Timing Role: Supervisory circuit asserting active-high RESET to hold ARM Cortex-M4 in reset until 3 V rail stabilizes post-power-up or recovers from brownout. Use Value: Prevents firmware corruption by guaranteeing 240 ms minimum reset duration and accurate 2.93 V trip point across −40°C to +125°C. | Use Scenario: Embedded in door module ECU to supervise 3 V domain supplying microcontroller, LIN transceiver, and window motor driver ICs. IC Role / Device Role / Timing Role: Active-high RESET generator triggered by 3 V rail collapse during load-dump or battery disconnect events. Use Value: Push-pull output eliminates external pull-up, reducing BOM count; 1 V minimum VCC operation ensures reset remains valid during severe undervoltage. |
| Medical Infusion Pump | Smart Energy Meter |
Use Scenario: Ensures safe startup and fault recovery in battery-powered infusion pump controlling stepper motor and pressure sensor interface. IC Role / Device Role / Timing Role: Resets safety-critical MCU upon battery voltage drop below 2.93 V or during cold-start from depleted Li-ion cell. Use Value: 17 μA quiescent current extends battery runtime; glitch immunity prevents false resets from motor commutation noise. | Use Scenario: Supervises 3 V real-time clock and metrology ASIC supply in DIN-rail mounted electricity meter operating in outdoor enclosures. IC Role / Device Role / Timing Role: Provides deterministic reset pulse to MSP430-based metrology processor during AC mains interruption or capacitor hold-up decay. Use Value: −40°C to +125°C qualification matches extended environmental rating; SC70 footprint saves space in compact meter PCB layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SASE+T | 2.93 V threshold, active-low push-pull output, same SC70 package, 1.2 μA higher max supply current | Requires inverted reset logic handling at MCU side; otherwise identical 3 V rail supervision function | Select when legacy designs require active-low reset signaling or MAXIM supply chain alignment |
| TPS3808G33DBVR | 3.3 V threshold (not 2.93 V), adjustable delay option, SOT-23-5 package, 1.1 μA typical supply current | Higher threshold limits use to 3.3 V systems; extra pins support manual reset and watchdog functions | Choose when system uses 3.3 V supply and requires programmable timeout or manual reset capability |
Compared with MAX809SASE+T, ADM810SAKS-REEL offers native active-high reset eliminating level-shifting; versus TPS3808G33DBVR, it delivers tighter 2.93 V threshold accuracy for 3 V rails and smaller SC70 footprint - critical for space-constrained industrial modules.

FAQ
What is the reset polarity of ADM810SAKS-REEL?
The ADM810SAKS-REEL provides an active-high RESET output. When VCC falls below the 2.93 V threshold, RESET goes low; when VCC rises above threshold, RESET remains high for 240 ms (typical) before deasserting. This behavior is explicitly defined in the functional description and pin configuration diagrams of the ADM810SAKS-REEL datasheet.
Does ADM810SAKS-REEL support operation below 2.0 V VCC?
Yes, ADM810SAKS-REEL is specified to operate down to 1.0 V VCC while maintaining valid RESET assertion. The device continues to monitor the supply and assert RESET correctly even during deep brownout conditions - a key feature confirmed in the General Description and Absolute Maximum Ratings sections of the ADM810SAKS-REEL datasheet.
What package type is used for ADM810SAKS-REEL?
ADM810SAKS-REEL is packaged in a 3-lead SC70 (JEDEC KS-3) outline, with dimensions of 2.00 mm × 2.10 mm × 0.95 mm. This information is explicitly stated in the Ordering Guide and Outline Dimensions sections of the ADM810SAKS-REEL datasheet, and matches the "KS-3" package option listed for this part number.
How does ADM810SAKS-REEL differ from ADM809SAKS-REEL?
The ADM810SAKS-REEL and ADM809SAKS-REEL share identical 2.93 V threshold and SC70 packaging, but differ in reset polarity: ADM810SAKS-REEL has active-high RESET, while ADM809SAKS-REEL has active-low RESET. Both use push-pull outputs, but their logic states during reset are inverted - a distinction clearly documented in the General Description and Pin Configurations sections of the ADM810SAKS-REEL datasheet.
Is ADM810SAKS-REEL RoHS compliant?
Yes, ADM810SAKS-REEL is RoHS compliant. The "Z" suffix in the part number (present in ADM810SAKS-REEL7 variants) explicitly denotes RoHS compliance per the Ordering Guide footnote, and the device carries appropriate marking (XX on bottom) as defined in the ADM810SAKS-REEL datasheet revision history and ordering table.
