Hi Team,

if I want to connect my controller to j3 header on evaluation board.is it require to provide 5V on pin no.3 from controller as well as 48 V supply from J1 header?  if both supply is required then how isolation between two supplies handled? 

Regards,

Aniket.

    Hi Aniket,

    J1 is battery power to the device to turn it on via battery pack supply. J3 is just for MCU 5V logic for UART RX/TX to reference so typically isolation could be a digital isolator but is not necessarily required to work the device properly.
