L6228
APPLICATION INFORMATION
A typical Bipolar Stepper Motor Driver application using L6228 is shown in Fig. 23. Typical component values
for the application are shown in Table 2. A high quality ceramic capacitor in the range of 100 to 200 nF should
be placed between the power pins (VS
A
and VS
B
) and ground near the L6228 to improve the high frequency
filtering on the power supply and reduce high frequency transients generated by the switching. The capacitor
connected from the EN input to ground sets the shut down time when an over current is detected (see Overcur-
rent Protection). The two current sensing inputs (SENSE
A
and SENSE
B
) should be connected to the sensing
resistors with a trace length as short as possible in the layout. The sense resistors should be non-inductive re-
sistors to minimize the di/dt transients across the resistor. To increase noise immunity, unused logic pins (except
EN) are best connected to 5V (High Logic Level) or GND (Low Logic Level) (see pin description). It is recom-
mended to keep Power Ground and Signal Ground separated on PCB.
