Description
The TLE 4727 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 0.7 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 a 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.
A stabilized 5 V output allows the supply of external components up to 5 mA. With the
error output the TLE 4727 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.
