Product Details

The EVAL-ADuM4122WHB1Z is a half bridge gate drive board that allows simple evaluation of the performance of the ADuM4122 when driving advanced Wolfspeed silicon carbide (SiC) metal-oxide semiconductor field-effect transistors (MOSFETs) and power modules. The EVAL-ADuM4122WHB1Z is intended to be used with the Wolfspeed SpeedVal Kit Modular Evaluation Platform and Wolfspeed clamped inductive load (CIL) test boards or half bridge evaluation boards and differential transceiver boards.

The EVAL-ADuM4122WHB1Z has an isolated return channel that is configured to read a negative temperature coefficient (NTC) thermistor and provides a variable frequency output corresponding to the resistance and temperature of the NTC.

The control and input interface for the EVAL-ADuM4122WHB1Z uses RS-422 signaling for improved noise and disturbance immunity, and the interface includes a 12 V power input for the EVAL-ADuM4122WHB1Z.

For full details on the ADuM4122, see the ADuM4122 data sheet, which must be consulted when using the EVAL-ADuM4122WHB1Z.
