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 tr...
