I am using the DRV 8842eval board for the brushed DC motor drive. In the spec sheet, the chopping current is related to a Risense that is not specified anywhere. I assumed that this is a resistance that the user wires down and the eval board would have that speced in the BOM.
The schematic of the eval board shows a value of 0.2 ohms and the BOM shows a value of 0.1 ohm. Which one is it?
Ahmad,
The BOM is correct....it is 0.1 ohm on the EVM. Sorry for the confusion.
