DESCRIPTION
The L9686 is a two frequency oscillator particu-
larly suitable as relay driver for flashing light con-
trol in automotive applications. The circuit may be
also used for other warning lamps like "handbrake
on" etc. The lamp failure detection is given by
doubling the flash repetition frequency. The
L9686 is supplied in minidip 8-lead and SO8 plas-
tic packages.
