Hi Infineon,

I need your help.
How can I sense my output phase current in my circuit?

thanks

Shunt resistors are the most common approach to measuring the output phase current. These resistors are placed after at the low side emitter to measure the current of each phase leg. Each product’s application note provides a reference design where shunt resistors are implemented.
