... Type TLE4729G Functional Description TLE4729G is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and other inductive loads that operate by constant current fully pin and function compatible except the current programming is inverse to the TLE4728G 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 ...

... With the two error outputs the TLE4729G signals malfunction of the device. Setting the control inputs low resets the error flag and by reactivating the bridges one by one the location of the error can be found. Pin Configuration (top view) Figure 1 Data Sheet TLE4729G Phase 1 ...

... Unused inputs should always be wired to proper voltage levels in order to obtain highest possible noise immunity. To prevent crossconduction of the output stages the TLE4729G uses a special break before make timing of the power transistors. This timing circuit can be triggered by short glitches (some hundred nanoseconds) at the phase inputs causing the output stage to become high resistive during some microseconds ...
