Maxim Integrated Input Output Controller, 1 I/O Channel, 6-Pin TDFN Package, Operating Voltage 2.97V-3.63V DS2485Q+T

Maxim Integrated DS2485Q+T is a high-performance Input Output Controller designed for industrial and electronic applications requiring efficient 1-Wire master protocol conversion between I2C hosts and 1-Wire slave devices. This interface IC leverages user-adjustable internal timers which eliminate timing burdens on the host processor, ensuring accurate communication and reliable data transfer. With selectable active or passive 1-Wire pull-up options and a strong pull-up feature, the DS2485Q+T supports power delivery needed by 1-Wire devices including EEPROMs and cryptographic modules.

The device operates over a voltage supply range from 2.97V through 3.63V and is capable of functioning reliably in harsh environmental conditions ranging from -40°C to 85°C, suitable for industrial and commercial equipment.

The compact 6-pin Thin Dual Flat No-lead (TDFN) package with a thickness of 800 micrometers and a length of 3.1 mm provides a space-saving solution optimized for surface mount technology. The controller supports a single I/O channel and does not include PCI, IDE, LAN, or DMA capabilities, focusing specifically on interface module functionality.

Electrical characteristics include a maximum current rating of ±20mA per pin and a junction temperature threshold of up to 150°C, ensuring durability under demanding operating conditions. This product does not carry automotive certifications but adheres strictly to standard semiconductor device requirements.

Typical use cases include embedded systems, industrial automation equipment, precision measurement instruments, and other electronic device applications requiring reliable 1-Wire communication interfaced with I2C subsystems.
