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

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.
