Description
The L6228Q is a DMOS fully integrated stepper
motor driver with non-dissipative overcurrent
protection, realized in BCDmultipower 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.
Available in VFQFPN32 5 mm x 5 mm package,
the L6228Q features a non-dissipative
overcurrent protection on the high side power
MOSFETs and thermal shutdown.
