Part Number: DRV8343-Q1
I am wondering whether a gate driver like DRV8343-Q1 or DRV8340-Q1 can drive MOSFETs to a current up to 40A or higher?
What determines whether a gate driver can drive 6 MOSFETs for a high current to 40A or higher? Is it based on total gate charge of QgTOT of MOSFET, or gate driver current? DRV8343-Q1 datasheet says it provides 1.5 mA to 1A peak source current and 3 mA to 2A peak sink current.
Another question is that whether DRV8343-Q1 or DRV8349-Q1 can be used for sensorless sinusoidal drive BLDC motor? If yes, how to implement?
Thanks,
John
