Application information
A typical bipolar stepper motor driver application using L6228Q is shown in Figure 25.
Typical component values for the application are shown in Table 7. A high quality ceramic
capacitor in the range of 100 to 200 nF should be placed between the power pins (VSA and
VSB) and ground near the L6228Q 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 overcurrent protection). The two current sensing inputs (SENSEA and
SENSEB) 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 resistors to minimize the
dI/dt transients across the resistor. To increase noise immunity, unused logic pins (except
EN) are best connected to 5 V (high logic level) or GND (low logic level) (see pin
description). It is recommended to keep power ground and signal ground separated on PCB.
