Product details
Overview
ADM810ZAKS-REEL from Analog Devices is a microprocessor supervisory circuit with active-high push-pull RESET output, 2.32 V reset threshold, and operation down to 1.0 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 2.5 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810ZAKS-REEL datasheet, ADM810ZAKS-REEL pinout, ADM810ZAKS-REEL application, or ADM810ZAKS-REEL equivalent, key selection criteria include reset polarity (active-high), SC70 package footprint, temperature-rated threshold accuracy (±0.07 V at 25°C), and compatibility with low-voltage microcontrollers requiring guaranteed reset assertion below 2.5 V.
Technical Context
The ADM810ZAKS-REEL implements a precision bandgap voltage reference and comparator architecture to detect VCC drops below 2.32 V with ±30 ppm/°C temperature coefficient. Its internal timer ensures 240 ms minimum reset assertion after VCC rises above threshold, independent of external components.
It features built-in glitch immunity against fast transients on VCC (up to 100 mV overdrive), operates with VCC as low as 1.0 V while maintaining valid RESET output, and delivers push-pull drive capability-no external pull-up required-supporting direct interface to CMOS inputs across 1.8 V to 5.5 V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.32 V (typical), ±0.07 V over −40°C to +85°C - enables reliable monitoring of 2.5 V supplies with margin |
| Supply Current | 17 μA (typical) at VCC < 3.6 V - supports battery-powered and ultra-low-power systems |
| VCC Operating Range | 1.0 V to 5.5 V - ensures reset functionality during brownout and deep undervoltage conditions |
| Reset Timeout | 240 ms (typical) power-on delay - holds processor in reset until supply stabilizes |
| Output Type | Active-high push-pull - 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 |
| Reset Output Low | 0.3 V max at 1.2 mA sink - ensures solid logic-low level for compatible microcontrollers |
| Reset Output High | 0.8 × VCC min at 150 μA source - guarantees valid logic-high across full VCC range (1.8–5.5 V) |
Pinout & Package
ADM810ZAKS-REEL 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 | Supply voltage input being monitored; functional down to 1.0 V |
| 2 | RESET | Active-high push-pull output; drives high when VCC ≥ 2.32 V and remains high for 240 ms after threshold crossing |
| 3 | GND | Ground reference for internal reference and output stage; must be connected to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Reset Polarity | Active-high push-pull output - directly interfaces to processors requiring high-valid reset (e.g., ARM Cortex-M, PIC, MSP430) |
| Low-Voltage Operation | Valid RESET assertion down to VCC = 1.0 V - ensures fail-safe behavior during severe brownouts |
| Glitch Immunity | Immune to transients ≤ 100 mV overdrive - prevents spurious resets from switching noise or ESD |
| Threshold Accuracy | ±2.5% over temperature (−40°C to +125°C) - reduces need for margin in supply design |
| Package Compatibility | SC70 footprint - enables high-density placement and matches industry-standard 3-pin supervisory footprint |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809ZTR | 2.32 V threshold, SOT-23-3 package, 140 ms min reset timeout, open-drain output | Requires external pull-up; shorter timeout may not meet stabilization requirements for slow-rising 2.5 V rails | Select when board space allows SOT-23 and open-drain flexibility is needed for wired-OR reset buses |
| TPS3801Z-23 | 2.33 V threshold, SC70-3, 200 ms min timeout, push-pull output, 1.6 V min VCC | Lower VCC floor (1.6 V vs. 1.0 V); tighter threshold tolerance (±0.5% vs. ±3%) but higher cost | Select when highest threshold accuracy is critical and supply rarely dips below 1.6 V |
Compared with MAX809ZTR and TPS3801Z-23, ADM810ZAKS-REEL uniquely combines 1.0 V operational floor, 240 ms guaranteed timeout, and SC70 footprint - making it optimal for space-constrained, ultra-low-voltage industrial controllers where robust brownout recovery is mandatory.

FAQ
What is the reset threshold voltage of the ADM810ZAKS-REEL?
The ADM810ZAKS-REEL has a nominal reset threshold voltage of 2.32 V at 25°C, with a guaranteed range of 2.25 V to 2.38 V over −40°C to +85°C and 2.22 V to 2.42 V over −40°C to +125°C. This precise threshold enables accurate monitoring of 2.5 V supply rails while maintaining sufficient margin against tolerance drift and noise.
Does the ADM810ZAKS-REEL require an external pull-up resistor?
No, the ADM810ZAKS-REEL does not require an external pull-up resistor because it features a push-pull RESET output. Unlike open-drain variants such as the ADM803, this configuration actively drives both high and low states, simplifying circuit design and reducing component count on the ADM810ZAKS-REEL PCB layout.
What is the minimum VCC voltage at which ADM810ZAKS-REEL remains functional?
The ADM810ZAKS-REEL remains fully functional down to VCC = 1.0 V, maintaining valid RESET output behavior-including correct assertion and deassertion timing-even during deep brownout conditions. This capability is confirmed across the full −40°C to +125°C temperature range per the official Analog Devices datasheet Rev. I.
How long is the power-on reset timeout for ADM810ZAKS-REEL?
The ADM810ZAKS-REEL provides a typical power-on reset timeout of 240 ms after VCC rises above the 2.32 V threshold. The datasheet specifies a minimum of 140 ms and maximum of 460 ms over −40°C to +85°C, ensuring sufficient time for microprocessor and peripheral stabilization before firmware execution begins on the ADM810ZAKS-REEL-equipped system.
Which package type is used by ADM810ZAKS-REEL?
The ADM810ZAKS-REEL uses a 3-lead SC70 (KS-3) package, measuring 2.00 mm × 1.25 mm × 0.95 mm with gull-wing leads. This RoHS-compliant, surface-mount package offers high board density and thermal performance suitable for compact industrial and automotive electronics where space and reliability are critical for the ADM810ZAKS-REEL implementation.
