Hi Team,

I have a question about the deadtime.I can set the dead time through device SPI,

If my PWM itself has a dead time, is the final output signal PWM dead time + device dead time？

Thanks

Hi Jenson,

Output PWM dead time is whichever dead time is longer, MCU dead time or DEAD_TIME setting. So if MCU dead time is 200ns, and DEAD_TIME setting is 50ns, output PWM dead time is 200ns.

Thanks,
Aaron
