MC33810 Blocks

 Note: PRELIMINARY.  This article is currently being created.

Some modules use the MC33810 as the driver for their LSO and/or Spark Outputs. MotoHawk contains a blockset of MC33810 configuration and diagnostic blocks that can be used to enable the additional current control and diagnostic capabilities of the MC33810 chip.

Modules

The MC33810 is used on:

• ECM-S12X-70
  
• ECM-564x-112 (ECM-OH)

MC33810 Spark Control Definition

The MC33810 Spark Control Definition block must first be placed in the model to define the global configurations of the MC33810 IC that relate to IGBT control. There will be one block for each MC33810 driver chip.

Diagnostics

The MC33810 has two types of outputs. There are four low side gate drivers and four pre-gate drivers that can function either as ignition IGBT or general purpose MOSFET gate pre-drivers. The fault reporting will depend on which outputs of the MC33810 are being used and whether the pregate drivers are configured for IGBT or MOSFET.

IGBT PreGate Drivers

When the FB0,1,2,or 3 outputs of the MC33810 are configured as IGBT pregate drives, the output expects that they will be used to drive an ingition coil. These would be typical on spark ECU outputs. The fault diagnostics of these outputs are first
