Can we connect the D-pin of multiple LITIX™ Basic+ ICs to only one capacitor?

Can we connect the D-pin of multiple LITIX™ Basic+ ICs to only one capacitor?

Yes, it is possible to use only one capacitor connected to the D-Pins of the LITIX™ Basic+ used for the same light function. In addition you need to connect all the ICs to the same error network. For that you need to use only one pull-up resistor connected to the ERRN-pin of all the ICs.

This is useful for example when several LITIX™ Basic+ ICs are used to realize one function, e.g. Stop, in order to set the delay time.

More details on the diagnosis and fault management can be found in the datasheet and the "Diagnosis and fault management" application note, available at https://www.infineon.com/cms/en/product/power/lighting-ics/litix-automotive-led-driver-ic/litix-basi...
