... IR21592. The design also includes a PIC16F628 microcontroller and an isolation circuit for connecting to a Digitally Addressable Lighting Interface (DALI). Other features include EMI filtering, transient protection and lamp fault protection. Not recommended for new designs please refer to IRPLDIM3 233 Kansas Street, El Segundo, CA 90245 USA By IRPLDIM2U rev.a ...

... FUNCTIONAL DESCRIPTION The IRPLDIM2U Demo Board consists of an EMI filter, an active power factor correction front end, a ballast control section, a digital control section and a resonant lamp output stage. A block diagram of the design is shown in Figure 3. The EMI filter blocks ballast generated noise. The power factor correction is used for sinusoidal input current and a regulated DC bus ...

... PIC16F628 collects the data through an isolation circuit. It then interprets the data and sends the appropriate signals to the ballast controller IR21592 if necessary or sends information back to the DALI. The PIC16F628 also performs fault detection and disables the IR21592 if a fault is present. 4 IRPLDIM2U www.irf.com ...

... This method strongly reduces the power/current use. The com- parator built into the PIC16F628 is used to set the threshold for detection of the incoming data. The signal RA2 is used as threshold for the comparator. 8 RB0 RB2 RB1 RA1 RA2 Fig. 7 DALI and Micro Controller connections IRPLDIM2U ENABLE TX_DALI RECEIVE-DRIVE RX_DALI MICRO-CONTROLLER www.irf.com ...
