Just want to check if below use is OK or not.
UCC27511 is a LS driver and I'd like to use it as below to drive HS MOS.
below is a buck HS output, using boostrap to drive HS MOS. Then connect SW to GND pin of UCC27511, BTST1 connect to Vdd of UCC27511,HIDRV connnect to IN+ of UCC27511, then connect OUTH/L to gate of HS mos, does it works?
I think it should work, but during test, BTST1-SW1 is only ~2V, but the REGN should be ~5V. so want to double check with you on this. Thanks.
