DESCRIPTION

The L6227 is a DMOS Dual Full Bridge designed for motor control applications, realized in MultiPower BCD technology, which combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device also includes two inde pendent constant off time PWM Current Controllers that performs the chopping regulation. Available in Power DIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) packages, the L6227 features a non-dissipative overcurrent protection on the high side Power MOSFETs and thermal shutdown.
