33812
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. This device is powered by SMARTMOS technology.
Features:
• Designed to operate over the range of ~4.7 V VPWR 36 V • Fuel injector driver - Current Limit - 4.0 A typical • Ignition pre-driver can drive IGBT or Darlington bipolar junction .
