Could you use one of the current EVMs like DRV2625EVM-CT or DRV2605EVM-CT ? We also have the DRV2625EVM-MINI that is ideal for making prototypes. With the DRV2625 , you can actually tie NRST, TRIG, and VDD together and when you pull them all high, the driver will startup and drive a LRA with default settings. If you have access to a GPIO that can source ~300mA, you can use it to drive the EVM-Mini and get a prototype up and running pretty quickly.
