Slave interface for a DALI network
A DALI interface is provided that includes a digital isolator having an input terminal and an output terminal. A DALI bus controlled by a master device controls a binary voltage state of a voltage rail. A DFET couples between the input terminal and the output terminal to control a voltage of the input terminal responsive to the control of the DALI bus by the master device. The digital isolator responds to the control of the input terminal voltage to drive a digital signal through an isolation barrier to control a voltage of the output terminal to control a slave lighting device.
