Advance Information
Multifunctional Ignition and
Injector Driver
The 33812 is 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. The 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.
Features:
? Designed to operate over the range of ~4.7 V ≤ V PWR ≤ 36 V
? Fuel Injector driver - Current Limit - 4.0 A Typical
? Ignition pre-driver can drive IGBT or Darlington bipolar junction
transistors
? Ignition pre-driver has independent high and low side outputs
