Tool/software:

Hello,

I have load requirement of 5ohm, 2.2uF and 50mH with 16V battery voltage, DRV8245 is configured as independent half bridge and load is connected to load side only.

Can DRV8245 is capable of driving this load or is there any restriction?

The capacitance is 2.2uF can DRV8245 able to drive this?

or is there any calculation that because of this inrush the driver can withstand?

If iam calculating through i=cdv/dt C=2.2uF , t=mosfet on time/slew rate 10V/usec ,converted to 16V(battery volatge), time is 1.6usec, i=22A for 1.6usec ,can this device handle 22A for 1.6usec?
