Product details
Overview
ADM810LAKS-REEL from Analog Devices is a microprocessor supervisory circuit in 3-lead SC70 package, providing active-high push-pull reset output with 4.63 V threshold, 140–460 ms reset timeout, and operation down to 1.0 V VCC for reliable power-on/power-down monitoring in embedded controllers.
For engineers reviewing the ADM810LAKS-REEL datasheet, ADM810LAKS-REEL pinout, ADM810LAKS-REEL application, or ADM810LAKS-REEL equivalent, key selection factors include reset polarity (active-high), SC70 packaging, −40°C to +125°C operating range, low 17 μA supply current, and compatibility with 5 V microprocessor systems requiring precise voltage supervision.
Technical Context
The ADM810LAKS-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms (typical) reset timer. It asserts RESET high when VCC falls below 4.63 V (±3% over temperature) and holds it for ≥140 ms after VCC rises above threshold.
Its push-pull output drives logic inputs directly without external pull-up, supports VCC as low as 1.0 V while maintaining valid reset assertion, and features 30 ppm/°C threshold temperature coefficient for stable performance across industrial and automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (±3% over −40°C to +125°C); ensures reliable reset initiation before 5 V system brownout. |
| Reset Polarity | Active-high push-pull; eliminates need for external pull-up resistor and simplifies interface to CMOS/TTL inputs. |
| Reset Timeout | 140–460 ms (−40°C to +85°C); guarantees sufficient hold time for microprocessor initialization and clock stabilization. |
| Supply Current | 17 μA (typical at VCC < 3.6 V); enables use in battery-powered and ultra-low-power embedded systems. |
| VCC Operating Range | 1.0 V to 5.5 V; allows valid reset assertion even during deep brownout or partial power loss. |
| Output Drive | RESET HIGH = 0.8×VCC (ISOURCE = 150 μA); RESET LOW = 0.3 V (ISINK = 1.2 mA); ensures robust logic-level compatibility. |
| Package | 3-lead SC70 (KS-3); 2.0 mm × 2.1 mm footprint ideal for space-constrained PCB layouts. |
Pinout & Package
ADM810LAKS-REEL uses a 3-lead SC70 (KS-3) package with exposed pad not electrically connected. Pin 1 = VCC, Pin 2 = RESET, Pin 3 = GND - confirmed per Figure 4 and Table 4 of Rev. I datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Supply Input | Monitored voltage rail; device operates and asserts reset based on this input; functional down to 1.0 V. |
| 2 (RESET) | Active-High Push-Pull Output | Drives high during normal operation; pulls low only during reset condition; no external components required. |
| 3 (GND) | Ground Reference | 0 V reference for all internal comparators and output stage; must be connected to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Precision Reset Threshold | 4.63 V ±3% over −40°C to +125°C enables accurate 5 V supply monitoring without calibration. |
| Glitch-Immune Comparator | Built-in immunity to fast transients on VCC prevents false resets during switching noise or ESD events. |
| Low-Power Operation | 17 μA typical supply current extends battery life in portable instrumentation and remote sensors. |
| Wide VCC Range Support | Operates from 1.0 V to 5.5 V, allowing use in multi-rail systems and enabling reset assertion during severe undervoltage. |
| SC70 Footprint | 2.0 mm × 2.1 mm body size reduces PCB area by >30% vs. SOT-23, critical for compact MCU modules. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
|
Use Scenario: Monitors 5 V supply rail powering ARM Cortex-M4-based controller in harsh factory environments with wide temperature swings and electrical noise. IC Role / Device Role / Timing Role: Supervisory IC asserting active-high RESET signal to hold MCU in known state during cold start, brownout, or EMI-induced voltage sag. Use Value: 4.63 V threshold matches nominal 5 V rail tolerance; 140–460 ms timeout accommodates slow-ramping industrial power supplies. |
Use Scenario: Embedded in door module ECU to supervise 5 V LDO output feeding CAN transceiver and window motor driver ICs. IC Role / Device Role / Timing Role: Active-high reset generator ensuring synchronized boot of microcontroller and peripheral ICs after battery reconnection or ignition cycle. Use Value: Push-pull output eliminates external pull-up, reducing BOM count; SC70 package saves space in tight under-dash enclosure. |
| Medical Infusion Pump | Smart Energy Meter |
|
Use Scenario: Ensures fail-safe startup of safety-critical MCU in battery-backed infusion pump where power interruption must trigger immediate motor halt and alarm. IC Role / Device Role / Timing Role: Voltage supervisor asserting RESET high until 5 V rail stabilizes post-battery swap or AC recovery, preventing erratic motor control. Use Value: 1.0 V minimum VCC operation guarantees reset validity even during final battery discharge phase. |
Use Scenario: Supervises 3.3 V microcontroller supply in ANSI C12.22-compliant meter exposed to utility grid transients and wide ambient temperatures. IC Role / Device Role / Timing Role: Precision 4.63 V monitor for upstream 5 V rail feeding isolated DC-DC converter; provides deterministic reset timing independent of load variation. Use Value: 30 ppm/°C tempco maintains threshold accuracy across −40°C to +125°C, meeting ANSI C12.20 long-term stability requirements. |
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 and −40°C to +125°C range, but active-low push-pull output. | Requires logic inversion or MCU pin configured for active-low reset; incompatible with systems expecting active-high assertion. | Select only if target MCU accepts active-low reset and board layout permits no change to RESET net routing. |
| MAX809LKA+T | 4.63 V threshold, active-high push-pull, but rated only to +85°C (not +125°C); 20 μA typical supply current. | Not suitable for under-hood automotive or high-temp industrial deployments; requires thermal derating above 85°C. | Choose only for commercial-temperature applications where cost sensitivity outweighs extended temperature coverage. |
Compared with ADM810LAKS-REEL, ADM809LAKSZ-REEL7 offers identical voltage and temperature specs but demands active-low system design, while MAX809LKA+T sacrifices industrial temperature range and adds 3 μA quiescent current-making ADM810LAKS-REEL optimal for high-reliability, wide-temperature, active-high reset implementations.

FAQ
What is the reset threshold voltage of the ADM810LAKS-REEL?
The ADM810LAKS-REEL has a nominal reset threshold voltage of 4.63 V, specified with ±3% tolerance over the full −40°C to +125°C operating temperature range. This value is confirmed in Table 3 and Table 1 of the Rev. I datasheet and applies specifically to the "L" variant designation in the ADM810 family.
Does the ADM810LAKS-REEL require an external pull-up resistor on the RESET pin?
No, the ADM810LAKS-REEL features a push-pull RESET output and does not require an external pull-up resistor. Its active-high output actively drives high during normal operation and low during reset, unlike the open-drain ADM803 series which mandates external biasing.
What package type is used for the ADM810LAKS-REEL?
The ADM810LAKS-REEL is packaged in a 3-lead SC70 (KS-3) outline, measuring 2.0 mm × 2.1 mm with 0.65 mm lead pitch. This is explicitly stated in the Ordering Guide and verified in Figure 15 of the Rev. I datasheet.
Can the ADM810LAKS-REEL operate with supply voltages below 2.0 V?
Yes, the ADM810LAKS-REEL remains functional and asserts valid RESET down to VCC = 1.0 V, as specified in the "VCC OPERATING VOLTAGE RANGE" row of Table 1. This capability ensures reliable reset behavior during deep brownout conditions common in battery-backed systems.
How does the reset timeout period vary with temperature for the ADM810LAKS-REEL?
The ADM810LAKS-REEL provides a minimum reset timeout of 140 ms and maximum of 460 ms over −40°C to +85°C, and 100 ms to 840 ms over +85°C to +125°C. These values are documented in the "RESET ACTIVE TIMEOUT PERIOD" row of Table 1 and reflect guaranteed timing across the full industrial temperature range.
