The L9686 is a two frequency oscillator particularly suitable as relay driver for flashing light control 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 plastic
packages.
