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.
