Hello,
We are using a DRV8301 gate driver for a rectifier application. I observed that some of our FETs generate excessive heat because they don't switch good. I saw that the nOCWT PIN is changing his level all the time. See the attached screen print. I do nothing with SPI communicatio and I have no load connected. What can trigger the nOCWT PIN when nothing is running and nothing is set over SPI. What is the effect to the ouptuts when nOCWT is going low?
CH1 = INH_A, CH2 = INL_A, CH3 = nOCWT
Thanks for your reply,
Markus
