Hi all
Would you mind if we ask DRV8350?
There is the description on the datasheet P13 as follows;
tDrive is Peak current gate drive time
There is the description on the datasheet P36 as follows;
After the MOSFET turnon or turnoff, the gate driver switches to a smaller hold I HOLD current to improve the gate driver efficiency.
<Question>
tDrive setting : 4000ns
For example, if the gate turns on(or turn off) with in 2000ns, does the gate driver switch to a smaller hold IHOLD current?
What we would like to know is ;
After gate turns on or off, the gate driver doesn't keep peak current in despite of tDrive remaining.
Is our recognition correct?
Kind regards,
