Part Number:DRV8703-Q1
Dear *,
a wan to drive a BDC with TI DRV8703-Q1.
Specification of Power Window motor is:
no load current <=3A
load rating current <=7A
locked current <=20A
1) I saw that the DRV8703-Q1 has some fault conditions like detecting the max current.
Please can you tell me how can i adjust the trip, in order to get the fault over-current condition?
2)Please can you explain the Ichop current -> should i set the Ichop to 7A or to 20A ?
3) what is the right way to size the Rshunt , if i want to measure the max load current ( i assume that the 7A is the max )
Rshunt= (Vso/Av)/Imax = (5V / 20) / 7A = 35mOhm ??
4) How does now the Rshunt influence the Ichop and the over-current ?
Best Regards.
