The motor is coupled into a H-bridge circuit consisting of four transistor switches (L1,L2,R1,R2), and this is connected to the battery supply (Ubat) and ground. A controller (130) operates the switches with an output logic stage (120) that connects to delay stages (110,115), each coupled to a pair of switches. The signals generated by the controller are logically used to provide motor direction signals or to maintain standby. |
