6.1 DALI data interface reference design
Below is the schematics and BOM of the DALI interface from the AirGlow shield included in the
AirGlow development kit . Please note that adjustments of components values might be needed in
this circuit to meet the timing requirements of the DALI standard IEC 62386-101:
Min Max
Rise/Fall time 3µs 15µs
Please consult IEC 62386-101 for definition of rise and fall time.
