Functional Description
TLE 4729 G is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and
other inductive loads that operate by constant current. It is fully pin and function
compatible except the current programming is inverse to the TLE 4729 G with an
additional inhibit feature. 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 0.7 A per phase at operating voltages up to 16 V.
The direction and value of current are programmable for each phase via separate control
inputs. In the case of low at all four current program inputs the device is switched to
inhibit mode automatically. 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
full-bridge configuration include fast integrated freewheeling diodes and are free of
crossover current. The device can be driven directly by a microprocessor in several
modes by programming phase direction and current control of each bridge
independently.
