Features & Applications

The L6228DTR is a DMOS Fully Integrated Stepper Motor Driver with non-dissipative Overcurrent Protection, realized in MultiPower-BCD technology, which combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a two-phase bipolar stepper motor including: a dual DMOS Full Bridge, the constant off time PWM Current Controller that performs the chopping regulation and the Phase Sequence Generator, that generates the stepping sequence.

Features:

  • Operating supply voltage from 8 to 52 V
  • 2.8 A output peak current (1.4 A DC)
  • RDS(on) 0.73 Ω typ. value @ TJ = 25 °C
  • Operating frequency up to 100 kHz
  • Non Dissipative Overcurrent Protection
  • Dual Independent Constant toff PWM CurrentControllers
  • Fast/Slow Decay Mode Selection
  • Fast Decay Quasi-Synchronous Rectification
  • Decoding Logic for Stepper MotorFull And Step Drive
  • Cross conduction protection
  • Thermal shutdown
  • Undervoltage lockout
  • Integrated fast free wheeling diodes

Applications:

  • Bipolar Stepper Motor
