I want to control the CDM10V with a 0-10v signal .
 
Can I know how to calculate how many pieces of CDM10V can be connected in parallel to a single output of  0-10v signal ?

Hi @Achraf1985 ,
Thanks for the clarification.

There are no such limitations for connecting the CDM10V in parallel. You can connect it as per the requirement.
In table 6 of CDM10V Datasheet, it is mentioned that the output current for Dimmer which is flowing out of the pin is typically 200 uA. Rdim+ PIN will not sink any current.

Please take note that you can connect as many as CDM10V to your application provided that the source at the RDIM+ pin can support the necessary current rating.

Feel free to contact in case of any further clarifications.

Regards,
Kanahaiya

Hi @Achraf1985 ,
Thanks for posting on the Infineon Developer community.

CDM10V is used to convert the Analog dimming signal to the Digital dimming signal having PWM frequency of 200Hz to 2kHz based on the signal of Rdim+ pin.

Please let us know about your end application and describe about the necessity of parallel connection.

Share the schematic you are using for your application.

Hi @Kumarkanahai 

Thank you for your reply.

Actually , i have made a dimmable DC LED driver with 0-10v signal.

i have used the CDM10V + ILD8150.

i will control many luminaires connected in parallel with one single 0-10v

So i need to calculate how many unites of CDM10V can be connected on parallel with one single signal 0-10v?

regards.
