DS2413 - 1-Wire Dual Channel Addressable Switch

General Description

The DS2413 is a dual-channel programmable I/O 1-Wire® chip.

The PIO outputs are configured as open-drain and provide up to 20mA continuous sink capability and off-state operating voltage up to 28V.

Control and sensing of the PIO pins is performed with a dedicated device-level command protocol.

Key Features

19-5316; 3/15 DS2413 1-Wire Dual Channel Addressable Switch GENERAL DESCRIPTION The DS2413 is a dual-channel programmable I/O 1-Wire® chip. The PIO outputs are configured as open-drain and provide up to 20mA continuous sink capability and off-state operating voltage up to 28V. Control and sensing of the PIO pins is performed with a dedicated device-level command protocol. To provide a high level of fault tolerance in the end application, the 1-Wire IO and PIO pins are all capable of withstanding continuous application of voltages up to 28V max. Communication and operation of the DS2413 is performed with the single contact Maxim/Dallas 1-Wire serial interface.
