Hi Omar,

Are you looking for a gate driver or integrated device? Our DRV8313 may be a good solution for an integrated device or our DRV8305 would also be a good device for a gate driver solution.

But this gate drive current i s< 3A
you can see my motor specification Maxon_496655. in joint piece

Hi Omar,

The DRV8305 would be a good match for this motor.

Thank you for your reponse

My probleme i sthe peak curent, as you see in the datasheet of my motor maxon is MAXON 496655 i want to control with lease o f2000 RPM, and as you see in the picture the motor require at the least of 3.6A

the driver the you propose hav e1A peak current

Hi Omar,

The DRV8305 is a Brushless DC gate driver, which can be used to control external MOSFETs rated for your peak motor current.

Our DRV8305 does not specify a peak Motor current because it is not placed in the drive path of the motor. Instead we specify a peak source / sink Gate Drive current, which is related to how quickly the DRV8305 will slew the external MOSFETs.

A typical application example of the DRV8305 controlling external MOSFETs rated for 30 Amps is shown on page 45 in Figure 18 of the DRV8305 datasheet.
