Document Number: MC33810 Freescale Semiconductor Rev. 11.0, 8/2014 Technical Data Automotive Engine Control IC 33810 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 ENGINE CONTROL either as ignition IGBT gate pre-drivers or as general purpose MOSFET gate pre-drivers. This device is powered by SMARTMOS technology. When configured as ignition IGBT gate pre-drivers, additional features are enabled such as spark duration, dwell time, and ignition coil current sense. When configured as a general purpose gate pre-driver (GPGD), 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.
