Adding Synchronous Switching to a Step-Down Switching Regulator Motor Drive Applications In applications where rotation is always in the same direction, a single LT1160 controlling a half-bridge can be used to drive a DC motor. One end of the motor may be connected either to supply or to ground as seen on Figure 3. A motor in this configuration is controlled by its inputs which give three alternatives: run, free running stop (coast- ing) and fast stop (“plugging” braking, with the motor shorted by one of the MOSFETs). To drive a DC motor in both directions the LT1162 can be used to drive an H-bridge output stage. In this configura- tion the motor can be made to run clockwise, counter- clockwise, stop rapidly (“plugging” braking) or free run (coast) to a stop. A very rapid stop may be achieved by reversing the current, though this requires more careful design to stop the motor dead. In practice a closed-loop control system with tachometric feedback is usually necessary. The motor speed in these examples can be controlled by switching the drivers with pulse width modulated square waves. This approach is particularly suitable for micro- computers/DSP control loops.
