Description

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.
