Connect VO+ and VO- of SI8271 gate driver on
Isolation Forum - Isolator
I have a question regarding the SI8271BB-IS gate drive (single gate drive with VO+ and VO- outputs). Our chip regularly burns down without any apparent reason. However, I connected both outputs (VO+ and VO-) directly together since I'm only using a common resistor for turn-on and turn-off. Could it be that there is a short overlap interval during the switching transient where both outputs are still driving their pin, thereby leading to a short circuit? Unfortunately the datasheet doesn't provide a lot of information about the output stage of the driver.
