CRD300DA12E-XM3 with CGD1700HB2M-UNA overcurrent protection threshold

ak47

Hello Experts,

We were looking at the CGD1700HB2M-UNA schematic and we had a few queries on the UCC21710 OC protection circuit,

Firstly what is the threshold it is designed for? (In terms amps not in Vce(sat) or Vds)

Looking at the UCC21710 data sheet , the Vocdet comes to around 5.7v, so the current threshold comes to 875 Amps, Could you experts verify this?

Also how have you assumed the Vf of the diode is 1v constantly, wouldn't it change with temperature and the current flowing through the diodes.?

Thanks ,

AK
