4 Powering the Board

Powering the THVD1454EVM is a quick process. To power on the board have top side of board facing upwards with J5 at the top of the EVM. From left to right the power terminal pins of J5 are connected to Earth, GND, and VCC respectively - this is also noted on the EVM.

If the test setup includes an Earth or Chassis connection, connect this to the left pin of J5. If no Earth or Chassis connection exist in the test setup connect this pin to GND. Next connect the GND connection to the center pin of J5 as this is what the THVD1454 references as its GND connection. Finally connect the positive terminal of a 3.3V to 5V supply voltage to the right most pin on J5. The board is now ready to be powered on; this is done correctly when the blue LED "D3" lights up.

The Proper orientation of the J5 Terminal Block is shown in Figure 4-1.
