Product details

Overview

ADM1817-20ART-REEL from Analog Devices is a tape-and-reel packaging variant of the ADM1817-20ART, a 2.0 V reset supervisor IC in SOT-23-3 package with 200 ms reset timeout, open-drain output, and −40°C to +85°C operating temperature range-used for microcontroller power-on reset sequencing in industrial control systems.

For engineers reviewing the ADM1817-20ART-REEL datasheet, ADM1817-20ART-REEL pinout, ADM1817-20ART-REEL application, or ADM1817-20ART-REEL equivalent, this page provides verified packaging specifications, reel orientation, ESD handling guidance, peel strength data, and feed direction per EIA-481 compliance.

Technical Context

The ADM1817-20ART-REEL is supplied on embossed plastic carrier tape sealed with static-dissipative cover tape, wound onto a rigid plastic reel compatible with standard automated placement equipment. It conforms fully to EIA Standard 481 for surface-mount component taping.

Pin 1 orientation is designated as C4 (per Figure 2 and Table 1), meaning Pin 1 is located at the upper left corner relative to the direction of feed and round sprocket holes. The reel rotates counterclockwise when held with sprocket holes facing the observer.

Key Specifications

Parameter	Value and Actual Design Meaning
Tape Width	8 mm - matches SOT-23-3 carrier tape standard for high-speed pick-and-place compatibility.
Tape Pitch	4 mm - ensures precise indexing and consistent part spacing during automated placement.
Reel Quantity (7")	3000 units - standard volume for production PCB assembly runs using 7-inch reels.
Peel Back Strength	10–100 g at 175°–180° angle - balances secure part retention with reliable cover tape release during de-taping.
ESD Protection	Static-dissipative tape & moisture barrier bag - maintains device integrity through handling and reflow.
Pin 1 Orientation	C4 - defines physical orientation for vision system alignment and correct mounting on PCB.

Pinout & Package

SOT-23-3 package (3-lead small-outline transistor) with gull-wing leads, body size 2.9 mm × 1.6 mm × 1.1 mm, JEDEC MO-178 compliant.

Pin/Terminal	Circuit Role	Design Meaning

GND	Ground reference	Return path for supply current and reset output sink current.
RESET	Open-drain reset output	Active-low signal asserted during power-up or brownout; requires external pull-up.

Key Features

Feature	Design Value
Reset threshold accuracy	±1.5% over temperature - ensures reliable microcontroller initialization across industrial ambient range.
Reset timeout period	200 ms nominal - long enough to stabilize power rails and clocks before releasing processor reset.

Equivalent & Alternatives

The following parts are listed as comparable options for similar reset supervisor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX809TRD2T-T	2.0 V threshold, 240 ms reset timeout, SOT-23-3, ±2% accuracy	Longer timeout may delay system startup; higher accuracy tolerance affects margin-critical designs	Select when longer reset hold time improves robustness against noisy supply rails.
TPS3808G01DBVR	2.0 V threshold, adjustable timeout (1.25 ms to 10 s), SOT-23-6, ±0.5% accuracy	Requires external capacitor for timing; extra pins enable manual reset and watchdog functions	Select when design requires configurable timeout or integration with system-level watchdog logic.

Compared with ADM1817-20ART-REEL, MAX809TRD2T-T offers longer reset assertion but looser threshold tolerance, while TPS3808G01DBVR provides precision and flexibility at the cost of added complexity and footprint-making ADM1817-20ART-REEL optimal for fixed-timing, space-constrained industrial resets.

FAQ

What is the tape width and pitch used for ADM1817-20ART-REEL?

The ADM1817-20ART-REEL is supplied on 8 mm wide carrier tape with 4 mm pitch, matching the SOT-23-3 package standard defined in Analog Devices' Tape and Reel Packaging specification (EIA-481 compliant). This ensures compatibility with high-speed pick-and-place machines and precise indexing during automated assembly.

What does "C4" pin orientation mean for ADM1817-20ART-REEL?

"C4" indicates that Pin 1 of the ADM1817-20ART-REEL is positioned at the upper left corner relative to the direction of feed and round sprocket holes on the tape-per Figure 2 and Table 1 in Analog Devices' packaging documentation. This orientation enables correct optical alignment and placement by automated vision-guided equipment.

Is ADM1817-20ART-REEL ESD-protected during shipment?

Yes, ADM1817-20ART-REEL is shipped in moisture barrier bags with static-dissipative tape and cover materials, meeting ANSI/ESD S20.20 requirements. Dry-packed reels receive full ESD protection; non-dry-packed versions ship in conductive-coated boxes or ESD bags-ensuring device integrity prior to PCB assembly.

What is the standard reel quantity for ADM1817-20ART-REEL on a 7-inch reel?

The standard quantity for ADM1817-20ART-REEL on a 7-inch reel is 3000 units, as specified in Table 1 under SOT-23-3 (RT) package designation. This volume supports mid-to-high-volume production runs while optimizing logistics and machine uptime.

Does ADM1817-20ART-REEL require external components for basic operation?

No, ADM1817-20ART-REEL operates autonomously with only V_CC, GND, and RESET connections. Its open-drain RESET output requires an external pull-up resistor (typically 10 kΩ to V_CC) to interface with microcontrollers or FPGAs-but no timing capacitors, resistors, or additional supervision circuitry are needed for standard 200 ms reset functionality.
