Product details
Overview
ADM810LAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 4.63 V reset threshold, −40°C to +125°C operating temperature range, 17 μA supply current, and SC70-3 package. It monitors VCC in embedded controllers and ensures reliable power-on reset assertion for 240 ms (typical) during microprocessor startup.
For engineers reviewing the ADM810LAKS-REEL7 datasheet, ADM810LAKS-REEL7 pinout, ADM810LAKS-REEL7 application, or ADM810LAKS-REEL7 equivalent, key selection criteria include reset polarity (active-high), minimum VCC operation down to 1.0 V, temperature-stable threshold (±0.06 V over −40°C to +85°C), and compatibility with 3 V/5 V logic interfaces without external pull-up.
Technical Context
The ADM810LAKS-REEL7 implements a precision voltage comparator with built-in glitch immunity and an internal 240 ms power-on reset timer. Its reset assertion remains valid even as VCC drops to 1.0 V, enabling robust brownout detection in wide-input industrial systems.
Unlike open-drain variants (e.g., ADM803), the ADM810LAKS-REEL7 features a push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH min, eliminating need for external pull-up resistors and simplifying interface to CMOS inputs requiring active-high reset signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (±0.06 V over −40°C to +85°C); precisely monitors 5 V rails with margin for tolerance drift |
| Reset Polarity | Active-high; directly drives CMOS reset inputs without level-shifting or pull-up components |
| Power-On Reset Timeout | 240 ms typical; holds microprocessor in reset until supply stabilizes post-power-up |
| Supply Current | 17 μA at VCC < 3.6 V; enables use in battery-powered or ultra-low-power embedded systems |
| Minimum Operating VCC | 1.0 V; maintains reset assertion during deep brownout conditions before system collapse |
| Package | 3-lead SC70 (KS-3); 2.0 mm × 1.25 mm footprint, compatible with high-density PCB layouts |
| Temperature Range | −40°C to +125°C; qualified for under-hood automotive, industrial control, and harsh-environment applications |
Pinout & Package
ADM810LAKS-REEL7 uses a 3-lead SC70 (KS-3) package: 1.25 mm × 2.0 mm body, 0.65 mm lead pitch, coplanarity ≤ 0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input; operates from 1.0 V to 5.5 V; powers internal comparator and timer |
| 2 | RESET | Active-high push-pull output; drives CMOS inputs directly; sinks 1.2 mA / sources 150 μA |
| 3 | GND | Ground reference for all internal circuitry; must be connected to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects transients up to 100 mV overdrive for ≤ 350 μs (ADM8xxR/S/T/Z), preventing false resets from supply noise |
| Low-voltage reset operation | Asserts RESET down to VCC = 1.0 V, ensuring fail-safe behavior during undervoltage faults |
| Precision threshold accuracy | ±1.3% initial tolerance (4.63 V ±60 mV at 25°C) and ±0.06 V over full industrial temperature range |
| Ultra-low quiescent current | 17 μA max at VCC < 3.6 V enables >10-year battery life in always-on monitoring applications |
| Push-pull output architecture | Eliminates external pull-up resistor, reduces BOM count, and improves noise immunity vs. open-drain alternatives |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|

IC Role / Device Role / Timing Role: Low-power supervisory IC holding meter SoC in reset until main supply reaches stable 5 V after wake-up event. Use Value: 17 μA supply current extends 10-year battery life; SC70 package enables compact meter PCB layout with minimal footprint impact. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809LAKSZ-REEL7 | Same 4.63 V threshold, −40°C to +125°C, SC70-3, but active-low push-pull RESET output | Requires inverted reset logic handling in MCU firmware or external inverter; not drop-in for active-high designs | Select only if system design accommodates active-low reset signaling and no hardware change is acceptable |
| MAX809LTRD7 | 4.63 V threshold, SOT-23-3, active-high RESET, but 20 μA supply current and −40°C to +85°C rating | Limited to commercial/industrial ambient; higher current reduces battery life in portable applications | Choose when cost sensitivity outweighs extended temperature and ultra-low-power requirements |
Compared with ADM809LAKSZ-REEL7, ADM810LAKS-REEL7 eliminates need for logic inversion; compared with MAX809LTRD7, it delivers 15% lower supply current and 40°C wider operating range-critical for automotive and energy infrastructure deployments.

FAQ
What is the reset output configuration of ADM810LAKS-REEL7?
The ADM810LAKS-REEL7 features an active-high push-pull RESET output. Unlike open-drain variants such as ADM803, it does not require an external pull-up resistor. It sources up to 150 μA when VCC is between 1.8 V and the reset threshold, and sinks up to 1.2 mA at minimum VCC, making ADM810LAKS-REEL7 suitable for direct interfacing with standard CMOS microcontrollers.
Does ADM810LAKS-REEL7 support operation below 2.0 V VCC?
Yes, ADM810LAKS-REEL7 asserts RESET down to VCC = 1.0 V, maintaining functional reset behavior well into brownout conditions. This capability is confirmed in the Absolute Maximum Ratings table and General Description section of the datasheet, where it states "reset output remains operational with VCC as low as 1 V." The ADM810LAKS-REEL7 continues to hold the reset signal active until VCC rises above 4.63 V and remains asserted for 240 ms thereafter.
What is the temperature coefficient of the reset threshold for ADM810LAKS-REEL7?
The reset threshold temperature coefficient for ADM810LAKS-REEL7 is 30 ppm/°C, as specified in the "RESET THRESHOLD TEMPERATURE COEFFICIENT" row of Table 1. This results in a maximum deviation of ±0.06 V over the −40°C to +85°C range, ensuring stable trip point performance across industrial operating conditions without requiring calibration.
Can ADM810LAKS-REEL7 replace ADM809LAKSZ-REEL7 in an existing design?
No, ADM810LAKS-REEL7 cannot directly replace ADM809LAKSZ-REEL7 without hardware or firmware changes because ADM809LAKSZ-REEL7 provides an active-low RESET output, whereas ADM810LAKS-REEL7 provides active-high. Swapping them would invert reset logic, potentially causing boot failure. If replacement is required, verify MCU reset pin polarity and update firmware or add an inverter stage.
What package type and dimensions does ADM810LAKS-REEL7 use?
ADM810LAKS-REEL7 uses the 3-lead SC70 package (JEDEC KS-3), measuring 2.00 mm × 1.25 mm × 0.90 mm with 0.65 mm lead pitch. Pin 1 is VCC, Pin 2 is RESET, and Pin 3 is GND. This package is distinct from the SOT-23 variant used by some other members of the ADM809/ADM810 family and requires specific land pattern geometry per Figure 15 in the datasheet.
