L6228Q

MOTOR DRIVER, DMOS, BIPLR, 2.8A, 32QFN.

The L6228Q is a DMOS fully integrated Stepper Motor Driver with non-dissipative overcurrent protection, realized in BCD technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a two-phase bipolar stepper motor including a dual DMOS full bridge, the constant off time PWM current controller that performs the chopping regulation and the phase sequence generator, that generates the stepping sequence. It features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.
