Abstract
Power tool devices described herein include a motor, an actuator configured to be actuated by a user, a plurality of power switching elements configured to drive the motor, a gate driver coupled to the plurality of power switching elements and configured to control the plurality of power switching elements, a first printed circuit board (PCB), an antenna, and a combined chip. The combined chip is located on the first PCB and is coupled to the actuator, the antenna, and the gate driver. The combined chip includes a memory and an electronic processor configured to determine that the actuator has been actuated, and provide, in response to determining that the actuator has been actuated, a signal to the gate driver, control the signal based on the motor position information, wirelessly transmit power tool device information to an external device, and wirelessly receive configuration information from the external device via the antenna.
