APPLICATION INFORMATION
A typical application using L6235 is shown in Figure 21. Typical component values for the application are shown
in Table 3. A high quality ceramic capacitor (C
2
) in the range of 100nF to 200nF should be placed between the
power pins VS
A
and VS
B
and ground near the L6235 to improve the high frequency filtering on the power supply
and reduce high frequency transients generated by the switching. The capacitor (C
EN
) 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 (SENSE
A
and SENSE
B
) should be connected to the sensing resistor R
SENSE
with a trace
length as short as possible in the layout. The sense resistor should be non-inductive resistor to minimize the di/
dt transients across the resistor. To increase noise immunity, unused logic pins 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.
