New Product Introduction

Infineon TLE472x a bipolar, monolithic IC

TLE472x is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and other inductive loads that operate by constant current

Infineon TLE472X product family picture

TLE472x 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 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 0.7 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.

 

Key features

  • 2 × 0.75 amp. / 50 V outputs

  • Fast free-wheeling diodes
  • Low standby current drain

 

Additional features

  • Full, half, quarter, mini step
  • Wide supply voltage range allows usage in different markets (e.g. automotive or industry)
  • All outputs short-circuit proof
  • Max. supply voltage 45 V or 52 V
  • Diagnosis via status flag to detect short circuit and over-temperature

 

Applications

  • Stepper Motor in automotive and industrial applications
  • Idle Speed control
  • Light leveling
