Driver

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.

SMALL ENGINE CONTROL IC

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

• Relay driver - current limit - 4.0 A typical

32 Pin SOICW EP

Applications:

• Single cylinder engine control

• Dual cylinder engine control

• Lamp driver- current limit - 1.5 A typical

• All external outputs protected against short to battery, overcurrent

• Ignition and other drivers protected against overtemperature

• Interfaces directly to MCU using 5.0 V parallel interface

• VCC voltage pre-regulator provides +5.0 V power for the MCU

• MCU Power On RESET generator

• MCU watchdog timer circuit with parallel refresh/time setting line

• Independent fault annunciation outputs for ignition, injector and relay drivers

• ISO-9141 K-Line transceiver for communicating diagnostic messages
