Product details
Overview
ADM810RART-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 2.63 V reset threshold, −40°C to +125°C operating temperature range, 17 μA supply current, and SOT-23-3 package. It monitors VCC in embedded controllers and ensures reliable power-on reset assertion for 240 ms (typical) during startup.
For engineers reviewing the ADM810RART-REEL7 datasheet, ADM810RART-REEL7 pinout, ADM810RART-REEL7 application, or ADM810RART-REEL7 equivalent, key selection criteria include reset polarity (active-high), minimum VCC operation down to 1.0 V, 140–460 ms timeout window across temperature, precision threshold tolerance (±2.5% at 25°C), and compatibility with 3 V/5 V microprocessor systems requiring brownout detection.
Technical Context
The ADM810RART-REEL7 implements a precision bandgap voltage reference and comparator to detect VCC falling below 2.63 V, asserting RESET high until VCC rises above threshold and remains stable for 240 ms (typical). Its internal timer guarantees deterministic reset timing 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 RESET functionality, and delivers push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min) with VOH ≥ 0.8×VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63 V ±2.5% at 25°C; holds system in reset until supply stabilizes above this level |
| Reset Timeout (Typ) | 240 ms; ensures microprocessor remains held in reset long enough for clock and supply stabilization |
| Supply Current | 17 μA at VCC < 3.6 V; enables use in battery-powered and low-power embedded systems |
| VCC Operating Range | 1.0 V to 5.5 V; supports operation during deep brownout and allows reset assertion even near power failure |
| Output Type | Push-pull active-high RESET; eliminates need for external pull-up resistor and interfaces directly with CMOS inputs |
| Temperature Range | −40°C to +125°C; qualified for automotive under-hood and industrial control environments |
| Reset Output Voltage High | ≥0.8×VCC at 1.8 V < VCC < VTH(min); ensures logic-high compatibility across varying supply rails |
| Reset Output Voltage Low | ≤0.4 V at VCC = VTH(min), ISINK = 3.2 mA; guarantees solid logic-low state during reset assertion |
Pinout & Package
ADM810RART-REEL7 uses a 3-lead SOT-23 package (JEDEC TO-236-AB, RT-3), 2.90 mm × 1.30 mm footprint, 1.45 mm height, with gull-wing leads and coplanarity ≤0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground Reference | 0 V reference for internal comparator and output stage; must be connected to system ground plane |
| 2 (RESET) | Active-High Push-Pull Output | Drives high when VCC ≥ 2.63 V and timeout complete; sinks current when low during reset assertion |
| 3 (VCC) | Supply Input | Monitored voltage rail; powers internal circuitry and defines reset threshold reference point |
Key Features
| Feature | Design Value |
|---|---|
| Active-high push-pull RESET | Eliminates external pull-up resistor, reduces BOM count, and ensures defined logic levels without external biasing |
| 240 ms typ. power-on reset timeout | Guarantees sufficient hold time for oscillator startup and PLL lock in microcontrollers before release |
| Operation down to VCC = 1.0 V | Enables valid reset signaling during severe brownout conditions where other supervisors fail silently |
| Glitch-immune comparator | Rejects transients up to 100 mV overdrive, preventing spurious resets from switching noise or ESD events |
| −40°C to +125°C qualification | Validated for extended temperature operation in automotive engine control units and industrial motor drives |
| 17 μA quiescent current | Minimizes standby power draw in always-on monitoring applications such as smart sensors and IoT edge nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809RTR | 2.63 V threshold, active-low open-drain RESET, 1.2 μA max supply current, SOT-23-3 | Requires external pull-up; incompatible logic polarity; lower power but no push-pull drive | Select when active-low reset and ultra-low power (<2 μA) are required, and pull-up resistor is acceptable |
| TPS3808G33DBVR | 3.3 V threshold, active-high push-pull RESET, 16 μA supply current, SOT-23-6 | Different threshold voltage; 6-pin package adds enable and manual reset pins not present in ADM810RART-REEL7 | Select when 3.3 V monitoring is needed and extra control features justify larger footprint and higher pin count |
Compared with MAX809RTR and TPS3808G33DBVR, ADM810RART-REEL7 uniquely combines 2.63 V threshold, active-high push-pull output, and SOT-23-3 packaging-enabling direct replacement in space-constrained 3 V systems where logic polarity and minimal external components are critical.

FAQ
What is the reset polarity and output structure of ADM810RART-REEL7?
The ADM810RART-REEL7 provides an active-high push-pull RESET output. Unlike open-drain variants (e.g., ADM803), it does not require an external pull-up resistor. When VCC falls below 2.63 V, RESET goes low; when VCC rises above threshold and the 240 ms timer expires, RESET transitions high and actively drives the line. This simplifies interface design with CMOS microcontrollers expecting active-high reset signals.
Does ADM810RART-REEL7 support operation below 2.63 V VCC?
Yes - ADM810RART-REEL7 remains functional and asserts RESET (low) down to VCC = 1.0 V, per its Absolute Maximum Ratings and specifications table. This capability ensures reliable reset signaling during deep brownout conditions where the supply may sag significantly below the 2.63 V threshold, a key differentiator versus many competing supervisors that cease operation below ~1.8 V.
What is the guaranteed reset timeout range for ADM810RART-REEL7 across temperature?
The ADM810RART-REEL7 guarantees a reset active timeout between 140 ms and 460 ms over −40°C to +85°C, and 100 ms to 840 ms over +85°C to +125°C. The typical value is 240 ms at 25°C. This wide window accounts for process and temperature variation while ensuring sufficient hold time for microprocessor initialization across all qualified conditions.
Can ADM810RART-REEL7 be used with both 3 V and 5 V microprocessor systems?
Yes - ADM810RART-REEL7 operates from VCC = 1.0 V to 5.5 V and its push-pull RESET output delivers VOH ≥ 0.8×VCC and VOL ≤ 0.4 V across that range. This allows seamless integration into 3 V, 3.3 V, and 5 V systems without level-shifting. Its 2.63 V threshold is optimized for monitoring 3 V rails, but the device itself functions correctly across the full supply range.
Is ADM810RART-REEL7 RoHS compliant and what package does it use?
Yes - ADM810RART-REEL7 is RoHS compliant (denoted by "Z" suffix in ordering guide, though not part of this specific variant's marking; full compliance confirmed via Analog Devices' official product documentation). It is supplied in a 3-lead SOT-23 package (JEDEC TO-236-AB, RT-3), with dimensions 2.90 mm × 1.30 mm × 1.45 mm and gull-wing leads compatible with standard reflow processes.
