MCZ33812AEK

Freescale Semiconductor Advance Information Document Number: MC33812 Rev. 5.0, 7/2010 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. 33812 SMALL ENGINE CONTROL IC 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 EK Pb-FREE SUFFIX 98ASA10556D 32 Pin SOICW EP transistors Ignition pre-driver has independent high and low side outputs ORDERING INFORMATION Relay driver - Current Limit - 4.0 A Typical Lamp driver- Current Limit - 1.5 A Typical All external outputs protected against short to battery, over-current Ignition and other drivers protected against over-temperature Interfaces directly to MCU Using 5.0 V parallel interface Device MCZ33812EK/R2 *MCZ33812AEK/R2 Temperature Range (TA) -40° to 125°C Package 32 SOICW-EP ...
