Description

TLE 4728 G is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and

other inductive loads that operate by 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 0.7 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. 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 free wheeling 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.

With the two error outputs the TLE 4728 G signals malfunction of the device. Setting the

control inputs high resets the error flag and by reactivating the bridges one by one the

location of the error can be found.
