Product details
Overview
ADM1818-10AKS-REEL from Analog Devices is a 3-pin open-drain microprocessor reset circuit with internal pull-up resistor, designed for monitoring 3.3 V power supplies. It features a 2.88 V (typical) reset threshold, 150 ms reset timeout, −40°C to +105°C operating temperature range, and SC70 package. It supports manual push-button reset initiation in embedded controllers and industrial instrumentation.
For engineers reviewing the ADM1818-10AKS-REEL datasheet, ADM1818-10AKS-REEL pinout, ADM1818-10AKS-REEL application, or ADM1818-10AKS-REEL equivalent, key selection criteria include trip point accuracy (±1.5% typical), low quiescent current (≤10 µA at 3.6 V), push-button compatibility, and SC70 footprint suitability for space-constrained PCB layouts.
Technical Context
The ADM1818-10AKS-REEL implements a precision voltage comparator with hysteresis and an integrated 150 ms power-on reset timer. Its open-drain output includes a factory-trimmed internal pull-up resistor (3.1–7.5 kΩ), eliminating external components for active-low reset assertion.
It operates across 1.2–5.5 V supply range and delivers guaranteed reset assertion during VCC ramp-up and brownout conditions. The device meets automotive-grade thermal performance (θJA = 146°C/W) and supports manual reset via RST-to-GND button press with sub-microsecond detection and 150 ms hold time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.88 V typical (2.80–2.97 V min/max); monitors 3.3 V supply with 13.6% undervoltage margin |
| Reset Timeout | 150 ms typical (100–250 ms); ensures stable power-up before releasing microprocessor reset |
| Supply Range | 1.2 V to 5.5 V; supports wide-input operation including battery-backed and multi-rail systems |
| Quiescent Current | ≤10 µA at 3.6 V; enables ultra-low-power operation in always-on subsystems |
| Output Type | Open-drain with internal pull-up (3.1–7.5 kΩ); simplifies interface to diverse logic families without external resistor |
| Push-Button Support | Detects ≥1 µs button press; asserts reset for 150 ms after release-enables field-serviceable system recovery |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood applications |
Pinout & Package
ADM1818-10AKS-REEL is housed in a 3-lead SC70 (KS-3) package, measuring 2.00 mm × 1.25 mm × 0.95 mm, JEDEC-compliant, with gull-wing leads and coplanarity ≤0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low open-drain reset output | Pulled low when VCC < threshold; floats high (via internal resistor) when VCC ≥ threshold; accepts manual button to GND |
| VCC | Supply input / monitored voltage rail | Both powers the IC and serves as the monitored signal; no separate sense pin required |
| GND | Analog and digital ground reference | Common 0 V return for comparator, timer, and output stage; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 2.88 V ±1.5% over temperature; eliminates need for external resistor divider calibration |
| Integrated 150 ms reset timer | Guaranteed delay from VCC rise above threshold to RST deassertion; prevents premature MCU boot |
| Internal pull-up resistor | 3.1–7.5 kΩ; enables direct connection to standard CMOS/TTL reset inputs without external components |
| Push-button reset interface | Sub-µs detection and 150 ms hold time; provides reliable user-initiated system recovery without additional logic |
| SC70 footprint | 1.25 mm width; saves >40% board area vs. SOT-23 while maintaining hand-solderability and reflow compatibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor with push-button reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM1813-10AKS-REEL | Same SC70 package and 2.88 V trip point, but rated for 5 V supply monitoring (4.35 V threshold variant); higher VCC max rating (5.5 V) | Designed for 5 V systems; not optimized for 3.3 V rail margin-requires derating for 3.3 V use | Select only if migrating legacy 5 V designs or requiring identical footprint with higher supply tolerance |
| MAX6326UT29D3+T | 2.93 V threshold, 140 ms timeout, SOT-23 package, no internal pull-up (requires external resistor) | Lacks integrated push-button support; requires external RC network for manual reset | Choose when cost sensitivity outweighs board space savings and design simplicity |
Compared with ADM1818-10AKS-REEL, ADM1813-10AKS-REEL offers identical timing and packaging but targets 5 V systems, while MAX6326UT29D3+T trades integration for lower unit cost at the expense of added passive components and reduced reliability in high-vibration environments.

FAQ
What is the exact reset threshold voltage of ADM1818-10AKS-REEL?
The ADM1818-10AKS-REEL has a nominal reset threshold of 2.88 V (typical), with guaranteed minimum and maximum values of 2.80 V and 2.97 V respectively, specified over the full −40°C to +105°C operating temperature range. This threshold is factory-trimmed and does not require external calibration.
Does ADM1818-10AKS-REEL require an external pull-up resistor?
No, ADM1818-10AKS-REEL includes an internal pull-up resistor ranging from 3.1 kΩ to 7.5 kΩ, enabling direct connection to standard CMOS or TTL reset inputs without external components. This feature reduces BOM count and improves layout reliability compared to open-drain supervisors requiring discrete resistors.
Can ADM1818-10AKS-REEL be used with a manual push-button reset?
Yes, ADM1818-10AKS-REEL explicitly supports manual reset via a push-button switch connected between the RST pin and ground. It detects button presses ≥1 µs and holds the reset output low for 150 ms after release-providing robust, bounce-immune field recovery without additional debouncing circuitry.
What package type and dimensions does ADM1818-10AKS-REEL use?
ADM1818-10AKS-REEL uses the SC70 (KS-3) package: 2.00 mm × 1.25 mm × 0.95 mm footprint with gull-wing leads, JEDEC-compliant outline, and maximum coplanarity of 0.10 mm. Its compact size saves >40% board area versus equivalent SOT-23 devices while maintaining reflow and hand-soldering compatibility.
What is the supply current consumption of ADM1818-10AKS-REEL at 3.6 V?
At VCC = 3.6 V and ambient temperature, ADM1818-10AKS-REEL draws ≤10 µA (typical 4 µA) when VCC exceeds the reset threshold and no load is applied to the RST pin. This ultra-low quiescent current supports energy-efficient operation in battery-backed or always-on subsystems.
