Dears,
We use TMS320F2810PBKQ,find some PCS have a function fail,as below picture show,we test GATE_C to GND,the OK board is 0.75V,the NG board is 0V,the OK board have voltage wave output,but the NG part no wave output.When we test this PIN to GND impedance discrete ,the NG and OK part is same ,Pls check.
Pls give us some design suggest.
