The L293, L293E and L298N dual-bridge ICs (see
box, ”inside the dual-bridge ICs”) significantly reduce
the problems encountered in the design of stepper-
motor drive circuitry. They can, for example,
simplify the design and increase the efficiency of
constant-current choppers. And with a single chip
replacing the transistors and predriver stages, circuit
performance improves. Best of all, the devices
have applications in complex as well as basic driver
