GENERAL DESCRIPTION
FEATURES
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.
