The 33810 is an eight channel output driver IC intended for automotive engine control applications. The IC consists of four integrated low-side drivers and four low-side gate pre-drivers. The low-side drivers are suitable for driving fuel injectors, solenoids, lamps, and relays. The four gate pre-drivers can function either as ignition IGBT gate pre-drivers or as general purpose MOSFET gate pre-drivers. This device is powered by SMARTMOS technology.
