This evaluation kit supports the NXP® MC33812, an engine control analog power IC intended for motorcycle and other single/dual cylinder small engine control applications.

  • The IC consists of three integrated low side drivers, one pre-driver, a +5.0 V, voltage pre-regulator, an MCU watchdog circuit, an ISO 9141 K-Line interface, and a parallel interface for MCU communication
  • Three low side drivers are provided for driving a fuel injector, a lamp or LED, and a relay or other load
  • The pre-driver is intended to drive either an Insulated Gate Bipolar Transistor (IGBT) or a bipolar Darlington transistor to control an ignition coil
  • This evaluation kit may be used with the KITUSBSPIDGLEVME.
