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.
