Product Overview

The L6208D is a DMOS fully integrated Stepper Motor Driver with non-dissipative overcurrent protection, realized in 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. It features a non-dissipative overcurrent protection on the high-side Power MOSFETs and thermal shutdown.
  • Non-dissipative overcurrent protection
  • Dual independent constant tOFF PWM current controllers
  • Fast/slow decay mode selection
  • Fast decay quasi-synchronous rectification
  • Decoding logic for stepper motor full and half step drive
  • Cross conduction protection
  • Thermal shutdown
  • Under-voltage lockout
  • Integrated fast free-wheeling diodes
  • 5.6A Output peak current (2.8A RMS)
  • 0.3R at Tj=25°C Typical RDS(ON)
  • Up to 100kHz operating frequency
