3.1 Hardware Requirements

The hardware used for evaluating this reference design is composed of the following:

  • TIDA-010985
  • LP-MSPM0G3507
  • USB Type-C® cable
  • USB isolator (to power the LP and protect the laptop). USB powering the entire system is the default method to evaluate the reference design.
  • Laptop
  • Four-channel oscilloscope
  • Two high-voltage differential probes rated for voltages higher than 1kV
  • Two single-ended probes for low-voltage signal measurements (TPP0500B)
  • A logic analyzer (Saleae logic 16) for debugging digital signals (optional)
  • HV DC power supply SL1250-1.2/UI+LXI
  • An interlocked safety box for HV testing safety
  • Optional 12V DC lab power supply (5W) if an external power supply is desired instead of the USB source of the LP for power (default option)
