If higher MOSFET continuous drain current ratings are required for the motor, parallel MOSFETs can be used for higher current capability. However, this requires special schematic and layout design requirements to switch both MOSFETs simultaneously because one MOSFET may turn on faster than the other due to process variation.

It is recommended to place the MOSFETs close together with a common gate signal that splits as close as possible to the MOSFETs gates. If gate resistance is required, calculate the equivalent resistance required for the equivalently rated MOSFET, and place the gate resistors as close as possible to the MOSFET’s gate input to dampen any coupling into the gate driver.
