Dual Channel Differential Isolated Half Bridge Gate Driver Board


Wolfspeed’s CGD1700HB2M-UNA is a half bridge gate driver board for evaluation of Wolfspeed C3M SiC MOSFET’s and modules. This board can be used in conjunction with Wolfspeed CIL boards or Evaluation kits. The board includes 2W power supplies with undervoltage protection and reverse polarity protection. Each of the two gate drive channels is also protected against over-current. The board includes circuits to read temperature from a Negative temperature coefficient (NTC) resistor when available.
