Automotive Engine Control IC
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

ENGINE CONTROL
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 ignition
coil 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.
