Maxim Integrated DS2413
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. Communication and operation of the DS2413 is performed with the single contact Maxim/Dallas 1-Wire serial interface.GENERAL DESCRIPTION
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.APPLICATIONS
