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.
