DUAL FULL-BRIDGE DRIVER

STMicroelectronics 

L298

This solution can drive until 3 Amps In DC operation

and until 3.5 Amps of a repetitive peak current.

OnFig 8 it is shownthe driving ofa twophasebipolar

stepper motor ; the needed signals to drive the in-

puts of the L298 are generated, in this example,

from the IC L297.

Fig 9 shows an example of P.C.B. designed for the

application of Fig 8.

Fig 10 shows a second two phase bipolar stepper

motor control circuit where the current is controlled

by the I.C. L6506.

Figure 8 : Two Phase Bipolar Stepper Motor Circuit.

This circuit drives bipolar stepper motors with winding currents up to 2 A. The diodes are fast 2 A types.

RS1 = RS2 = 0.5 Ω

{ D1 to D8 = 2 A Fast diodes

VF ≤ 1.2 V @ I = 2 A
