L6206
APPLICATION INFORMATION
A typical application using L6206 is shown in Fig. 12. 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 L6206 to improve the high frequency filtering on the power supply and
reduce high frequency transients generated by the switching. The capacitors connected from the EN

and EN

nodes to ground set the shut down time for the Brgidge A and Bridge B respectively when an
over current is detected (see Overcurrent Protection). The two current sources (SENSE
A
and SENSE
B
) should
be connected to Power Ground with a trace length as short as possible in the layout. To increase noise immu-
nity, unused logic pins are best connected to 5V (High Logic Level) or GND (Low Logic Level) (see pin descrip-
tion). It is recommended to keep Power Ground and Signal Ground separated on PCB.
