Application information
A typical application using L6208Q is shown in
application are shown in
nF should be placed between the power pins (VS
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 input to
ground set the shutdown time when an overcurrent is detected (see
current sensing inputs (SENSE
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
separate on the PCB.
