Other Parts Discussed in Thread: TMS320F28335

Dear Sir,

I am working on TMS320F28335 DSP motor control kit hardware in the reference design of TMS320F28335 available in Texas site i have found that in power stage design they have used TPS767D301 IC but i found that in the reference design  they have shown that 19th pin is sense pin and connected it to output but as per datasheet 19th pin is NC & it should be left open now which circuit i should follow the reference design available on  texas site or datasheet

Iam also attaching the reference design for your reference

Thanks & Regards

    The TPS767D301 datasheet is correct and pin 19 is a N/C pin.  Connecting pin 19 to an output will not damage the IC so you can use the schematic as-is, ground pin 19, or leave it floating.  A good design practice is to ground pins that do not have intenral connections.
