Engine Control IC 32-Pin SOIC W EP Rail

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. When configured as ignition IGBT gate pre-drivers, additional features are enabled such as spark duration, dwell time, and transformer current sense. When configured as a general purpose gate pre-driver, the 33810 provides external MOSFETs with short circuit protection, inductive flyback protection and diagnostics. The device is packaged in a 32 pin (0.65mm pitch) exposed pad SOIC.
