2.4 Hardware Setup

The EVM hardware is designed and kitted to simplify setup and begin driving loads. The EVM comes with the jumpers placed at the appropriate location in the headers. The description of the jumpers, also called shunts, are exlained in Table 2-1 and Table 2-2.

Note:
  • The DRV81545EVM can function with or without GUI software. To ensure proper operation, please verify that the SW1 switch (GUI/HW) is set to the correct state.
  • Confirm that the shunts on connectors J6 through J11 are properly configured

Before connecting the EVM to the GUI software, follow these steps:

  1. Connect EVM to PC via USB connector. LED D5 (XDS110), and LED D3 (3.3V), must be solid ON. LED D1 (MCU STATUS) needs to be toggling ON/OFF at a 1s intervals.
  2. Connect power supply (less than 55V for DRV81545, less than 65V for DRV81646 / DRV81646DGQ) to power connector.
  3. Turn ON power supply. LED D18 (VM) turns ON. See Figure 2-6 for setup image. The EVM is designed with built-in reverse polarity protection to prevent damage from incorrect power supply connections. If the LED D18 indicator fails to illuminate, ensure that the power supply polarity connection is correctly configured.
  4. Connect load to the appropriate output connector.
  5. Set up is now complete. See Figure 2-6 for setup image.
