L6227：DMOS dual full bridge driver with PWM current controller
The L6227 device is a DMOS dual full bridge designed for motor control applications, realized in BCD technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device also includes two independent constant off time PWM current controllers that performs the chopping regulation. Available in PowerDIP24 (20 + 2 + 2), PowerSO36 and SO24 (20 + 2 + 2) packages, the L6227 device features a non-dissipative overcurrent protection on the high-side Power MOSFETs and thermal shutdown.
