Demonstration board using a dual full-bridge L6227Q for motor control applications

The L6227Q is a DMOS dual full-bridge designed for motor control applications, realized in BCD multipower technology.

The L6227Q features thermal shutdown and a non-dissipative overcurrent protection on the high-side power MOSFETs plus a diagnostic output that can be easily used to implement the overcurrent protection.

The device also includes two independent constant off-time PWM current controllers which perform the chopping regulation.

Key Features

  • Operating frequency up to 100 kHz
  • Non dissipative overcurrent protection
  • Dual independent constant tOFF PWM current controllers
  • Slow decay synchronous rectification
  • Cross conduction protection
  • Thermal shutdown
  • Undervoltage lockout
  • Integrated fast free wheeling diodes
