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.
