2.2.4 Supply Input

Figure 2-4 illustrates the portions of the EVM associated with the main supply input powering the DRV824x-Q1 or DRV814x-Q1 device, and the associated loads. Starting from the upper-left, and working clockwise around the image:

  • Supply reverse polarity protection. The Texas Instruments LM74610QDGKRQ1 drives a Texas Instruments CSD18513Q5A 40 V 100 A N-channel MOSFET.
  • Fuses.
    Note: DRV8243-Q1 EVMs only has a single fuse populated
  • Not pictured (underside): TVS diode.
  • High current supply input with screw terminals. Supply shall be between +4.5 VDC to +36 V. Test points are provided.
  • Pi filter section comprising two 50 V 150 uF capacitors and a 1 mH inductor (misc. passive components omitted from image for simplicity).
