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.
The L6227 is a DMOS Dual Full Bridge driver designed for motor control applications, realized in MultiPower BLOCK technology. It combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device includes two independent constant off time PWM Current Controllers that perform chopping regulation.
Available in PowerDIP24, PowerSO36, and SO24 packages, the L6227 features non-dissipative overcurrent protection on the high side Power MOSFETs and thermal shutdown. It is suitable for driving bipolar stepper motors and dual DC motors.
