DS2401Z+

Specialized ICS Overview

The DS2401Z+ is a silicon serial number integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a guaranteed unique 64-bit ROM ID for absolute traceability, comprising an 8-bit family code (01h), a 48-bit serial number, and an 8-bit CRC tester. The device utilizes a minimalist 1-Wire interface requiring only a single data pin and ground return. Operating within a voltage range of 2.8V to 6.0V and an industrial temperature range of -40°C to +85°C, it draws a maximum input load current of 5µA. The component is housed in a SOT-223-4 surface-mount package.

• Extended Voltage Range of 2.8V to 6.0V with Zero Standby Power Required
• Industrial Temperature Range from -40°C to +85°C

Specialized ICS Applications

• PCB Identification
• Network Node ID
• Equipment Registration

Specialized ICS Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and lead configuration. The 'Z+' designation indicates a lead-free/RoHS-compliant package in the SOT-223 form factor. Confirm that the application environment remains within the specified 2.8V to 6.0V supply voltage and -40°C to +85°C operating temperature limits to ensure functional reliability.

Specialized ICS Selection Notes

Select the DS2401Z+ when a compact surface-mount solution is required for 1-Wire network identification. This variant is suitable for applications needing a 4-pin SOT-223 footprint instead of the through-hole TO-92 or TSOC options. Ensure the bus controller circuit includes an appropriate pullup resistor, typically between 1.5kΩ and 5kΩ, to maintain signal integrity during Read/Write time slots.

Specialized ICS Part Context

The DS2401 series serves as an electronic registration number providing a unique identity via a minimal electronic interface. It acts as an upgrade to the DS2400, offering full reverse compatibility while adding multi-drop capability for multiple devices on a single data line. The Z+ variant specifically denotes the SOT-223 surface-mount package option within this product family.
