Dual Channel Differential Isolated Half Bridge Gate Driver Board
CGD1700HB2M-UNA
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 features over-current protection, an active Miller clamp, and separate turn-on and turn-off gate resistors for effortlessly tuning switching speeds. The board includes circuitry to read the temperature from a Negative Temperature Coefficient (NTC) resistor when available. The gate driver board also features MMCX connectors to accurately measure high-side and low-side VGS with fiber optically isolated probes such as the TIVP1 from Tektronix®.
