APPLICATION INFORMATION
A typical application using L6207 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 (VS
A
and VS
B
) and ground near the L6207 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
A
and EN
B
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 (SENSE
A
and SENSE
B
) 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 EN
A
and EN
B
) 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.
