Hi Akshay,

Thanks! And how do you choose the current sense resistors? Why do you choose 0.03 ohm in the EVM, and choose 0.1ohm in the TIDA 010273? Could you pls share the guideline?

BR,

Skylar

Skylar,

The current shunt resistors will depend on the current requirements needed for the customer system. If higher current is required, the sense resistors will trend towards smaller values in order to ensure the voltage drop is not too large and power loss is not too high.

For lower current, larger shunts will be used to ensure enough voltage can be measured across the shunt to properly sense the current.

Regards,

Ryan
