This reference design is a 3-phase 1/2 H-Bridge Motor Drive solution with independent FET capability that interfaces with solenoid loads found in Gasoline and Diesel Engine Platforms such as automotive solenoids, bidirectional Brushed- or Brushless-DC motors, unidirectional Brushed-DC motors, and relays.
Internal Combustion Engines (ICE) will be the largest market for Engine Control Units (ECUs) until the emergence of Hybrid Electric Vehicles, and engine platforms can require up to as many as 60 general purpose outputs. The DRV8343-Q1 motor driver is featured on this design and supports up to 6 independent loads per device, with configurability for any architecture of load output configurations.
This reference design features 4 distinct outputs to showcase the versatility of the DRV8343-Q1: solenoid with push-pull configuration, solenoid with high-side/low-side gate drivers, and independent high-side / low-side loads. These loads are independently driven using an automotive TMS320F28035 C2000 high-efficiency 32-bit microcontroller.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
