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.
