The L6227Q is a DMOS dual full bridge driver with PWM current controller from STMicroelectronics, which is designed for motor control applications.
The L6227Q is a DMOS dual full bridge driver designed for motor control applications, realized in BCD multipower technology. It combines isolated DMOS power transistors with CMOS and bipolar circuits on a single chip. The device includes two independent constant off time PWM current controllers that perform chopping regulation and features non-dissipative overcurrent protection on the high side power MOSFETs.
