2.1 Power Requirements

The TPS7H3xx4EVM-CVAL board requires 3 power rails (VIN, VPULL_UP1, and VPULL_UP2) to be externally provided by power supplies. These can be separate or shared as long as the voltage ranges of each are respected. The test results shown in this user guide were performed with 1 power supply used for VIN and 1 power supply shared by VPULL_UP1 and VPULL_UP2.

  • 3V ≤ VIN ≤ 14V
  • 1.6V ≤ VPULL_UPx ≤ 7V
