Dear expert,
Customer use IDRV_CTRL1 to optimized EMI. And there is 100ohm between DRV8718 Gx to FET Gate for current limitation.
They compared IDRV_CTRL1 max 62mA with min 50uA(low current mode) and find VGx slew rate is 39.193V/us vs. 14.595V/us.
Is it normal? Current is changed by 1000 times but VGx slew rate is only reduced over half.
And slew rate of current flew from Drain to Source doesn't change at all. This is as expected, right?
