Product details
Overview
ADM810LART-REEL from Analog Devices is a microprocessor supervisory circuit in 3-lead SOT-23 package, providing active-high push-pull RESET output with 4.63 V reset threshold, 240 ms typical power-on reset timeout, and operation down to 1.0 V VCC. It monitors supply voltage in embedded controllers and ensures reliable system initialization during power-up, brownout, and power-down events.
For engineers reviewing the ADM810LART-REEL datasheet, ADM810LART-REEL pinout, ADM810LART-REEL application, or ADM810LART-REEL equivalent, key selection criteria include reset polarity (active-high), push-pull output drive capability, −40°C to +125°C operating temperature range, and compatibility with 5 V nominal supply rails requiring precise voltage monitoring.
Technical Context
The ADM810LART-REEL implements a precision bandgap-based voltage reference and comparator to detect VCC falling below 4.63 V (±3% over temperature), asserting RESET high until VCC exceeds threshold and remains stable for 240 ms. Its internal timer guarantees deterministic reset timing independent of external components.
It features built-in glitch immunity against fast VCC transients up to 100 mV overdrive, operates with only 17 μA supply current at 3.6 V, and maintains functional RESET output down to VCC = 1.0 V - enabling robust supervision in low-voltage brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V ±3% over −40°C to +125°C - ensures reliable detection of 5 V rail collapse before microprocessor malfunction. |
| Reset Timeout | 240 ms typical power-on delay - holds processor in reset long enough for clock and supply stabilization. |
| Supply Voltage Range | 1.0 V to 5.5 V - supports supervision during deep brownout and enables use with wide-input power supplies. |
| Supply Current | 17 μA at VCC < 3.6 V - minimizes impact on battery life in portable and always-on embedded systems. |
| Output Type | Active-high push-pull - eliminates need for external pull-up resistor and drives CMOS/TTL inputs directly. |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood, industrial control, and harsh-environment applications. |
| Reset Output Low | ≤0.4 V at 3.2 mA sink - guarantees solid logic-low state when deasserted, compatible with 3.3 V/5 V I/O standards. |
| Reset Output High | ≥0.8 × VCC at 150 μA source - ensures valid logic-high across full VCC range without level-shifting. |
Pinout & Package
ADM810LART-REEL uses a 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB standard, with 1.30 mm × 2.90 mm footprint and 0.95 mm height. Pin 1 = VCC, Pin 2 = RESET, Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Supply Input | Monitored voltage rail input; device draws current and asserts reset when this falls below 4.63 V. |
| 2 (RESET) | Active-High Push-Pull Output | Drives high during normal operation; goes low only during reset condition - directly interfaces to µP /C reset pin. |
| 3 (GND) | Ground Reference | Common return path for internal reference and output stage; must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 4.63 V threshold | ±3% tolerance over −40°C to +125°C - eliminates need for external trimming in 5 V systems. |
| 240 ms fixed reset timeout | Internally timed, no external capacitor required - reduces BOM count and layout area. |
| 17 μA ultra-low quiescent current | Enables >10-year battery life in coin-cell-powered IoT sensors and backup supervisors. |
| 1.0 V minimum VCC operation | Guarantees reset assertion even during severe brownout - prevents undefined microprocessor behavior. |
| Glitch-immune comparator | Rejects transients ≤100 μs duration at up to 100 mV overdrive - avoids false resets from switching noise. |
| Push-pull active-high output | Eliminates external pull-up resistor and simplifies interface to modern microcontrollers with active-high reset inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809LUR-T | Same 4.63 V threshold and SOT-23 package, but active-low open-drain output requiring external pull-up. | Suitable where legacy designs use active-low reset inputs; not drop-in due to polarity and drive type mismatch. | Select only if system requires active-low reset signaling and board layout accommodates pull-up resistor. |
| TPS3808G01DBVR | Adjustable threshold via external resistor divider; 200 ms reset timeout; 1.8–6.0 V VCC range; higher 25 μA quiescent current. | Better for multi-rail systems needing custom thresholds, but adds component count and lacks guaranteed 240 ms timing. | Prefer when design flexibility outweighs BOM simplicity and deterministic timing is secondary. |
Compared with MAX809LUR-T and TPS3808G01DBVR, ADM810LART-REEL delivers guaranteed active-high push-pull timing with zero external components - reducing risk of reset failure in safety-critical 5 V systems where pin compatibility and timing predictability are mandatory.

FAQ
What is the reset polarity and output structure of ADM810LART-REEL?
The ADM810LART-REEL provides an active-high push-pull RESET output. When VCC is above 4.63 V and stable, RESET is driven high; when VCC drops below threshold or during power-up, RESET is driven low for 240 ms. This eliminates the need for an external pull-up resistor and ensures clean, rail-to-rail logic levels compatible with modern microcontrollers requiring active-high reset inputs.
Does ADM810LART-REEL support operation at temperatures beyond commercial grade?
Yes, ADM810LART-REEL is specified for −40°C to +125°C operation, making it suitable for extended temperature applications including automotive under-hood modules, industrial motor drives, and outdoor infrastructure equipment. Its reset threshold drift is limited to ±3% across this full range, and supply current remains stable at 17 μA (VCC < 3.6 V).
Can ADM810LART-REEL monitor supply voltages lower than 4.63 V?
No - ADM810LART-REEL is factory-trimmed to a fixed 4.63 V reset threshold, optimized for 5 V nominal rails. For lower-voltage supervision (e.g., 3.3 V or 2.5 V), Analog Devices offers other variants in the same family: ADM810TARTZ-REEL7 (3.08 V), ADM810SARTZ-REEL7 (2.93 V), or ADM810RARTZ-REEL7 (2.63 V). Each has identical timing and package but different threshold calibration.
How does ADM810LART-REEL handle fast transients on the VCC line?
ADM810LART-REEL incorporates a glitch-immune reset comparator that rejects transients ≤100 μs duration with up to 100 mV overdrive (VTH – VCC). This prevents false resets caused by switching regulator noise, ESD events, or load-dump spikes - a critical feature verified in Figure 11 of the datasheet and essential for reliable operation in electrically noisy environments.
Is ADM810LART-REEL RoHS compliant and what packaging format does it use?
Yes, ADM810LART-REEL is RoHS compliant (indicated by the "Z" suffix in ordering code) and supplied in tape-and-reel format (REEL designation) for automated SMT assembly. It uses the industry-standard 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB, with dimensions 2.90 mm × 1.30 mm × 0.95 mm and lead pitch of 0.95 mm - fully compatible with standard pick-and-place equipment.
