APPLICATION INFORMATION
A typical application using L6227 is shown in Fig. 16. Typical component values for the application are shown
in Table 3. 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 L6227 to improve the high frequency filtering on the power supply and
reduce high frequency transients generated by the switching. The capacitors connected from the ENA and ENB
inputs to ground set the shut down time for the BrgidgeA and BridgeB respectively when an over current is de-
tected (see Overcurrent Protection). The two current sensing inputs (SENSEA and SENSEB) should be connect-
ed 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 ENA and ENB) are best connected to 5V (High Logic Level) or GND (Low Logic Level) (see
pin description). It is recommended to keep Power Ground and Signal Ground separated on PCB.
