Product Details

The EVAL-ADuM4121WHB1Z is a half-bridge gate drive board that allows simple evaluation of the performance of the ADuM4121 when driving advanced Wolfspeed silicon carbide (SiC) metal-oxide semiconductor field-effect transistors (MOSFETs) and power modules. The EVAL-ADuM4121WHB1Z is intended to be used with the Wolfspeed SpeedVal Kit modular evaluation platform and Wolfspeed clamped inductive load (CIL) test boards or with the half-bridge evaluation boards and differential transceiver boards.

The EVAL-ADuM4121WHB1Z has an isolated return channel that is configured to read a negative temperature coefficient (NTC) thermistor and provide a variable frequency output corresponding to the resistance and temperature of the NTC.

The control and input interface for the EVAL-ADuM4121WHB1Z uses RS-422 signaling for improved noise and disturbance immunity and includes a 12 V power input for the EVAL-ADuM4121WHB1Z.

For full details on the ADuM4121, see the ADuM4121 data sheet, which must be consulted when using the EVAL-ADuM4121WHB1Z.
