Description
TLE 4726 is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and
other inductive loads that operate on constant current. The control logic and power
output stages for two bipolar windings are integrated on a single chip which permits
switched current control of motors with 0.75 A per phase at operating voltages up to
50 V.
The direction and value of current are programmed for each phase via separate control
inputs. A common oscillator generates the timing for the current control and turn-on with
phase offset of the two output stages. The two output stages in a full-bridge configuration
have integrated, fast free-wheeling diodes and are free of crossover current. The logic
is supplied either separately with 5 V or taken from the motor supply voltage by way of
a series resistor and an integrated Z-diode. The device can be driven directly by a
microprocessor with the possibility of all modes from full step through half step to mini
step.
