BQ76PL455EVM: BQ76PL455A-Q

Part Number: BQ76PL455EVM

Hi Team,

if I want to connect my controller to j3 header on evaluation 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? 



  • 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.
