This FRDM evaluation board features the MC34933 two channel H-Bridge driver which can drive a single stepper motor or 2 brushed DC motors.
The FRDM-34933EVB has been designed to easily fit on top of the FRDM-KL25Z.
The MC34933 uses Our proprietary SMOS8 Bi CMOS process to deliver a low power device, and operates from 2.0 V to 7.0 V, with a maximum quiescent current of 100 μA for the motor drive supply and 400 μA for the Control Logic supply. The MC34933 employs a VCC detection circuit to sense when the logic supply switches to an off-state with a maximum current of 1 μA to extend battery life.
