DS2413
1-Wire Dual-Channel
Addressable Switch
GENERAL DESCRIPTION
BENEFITS AND 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 1-Wire serial interface.
