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.
