EVAL-ADUM4146WHB1Z

EVAL-ADuM4146WHB1Z is a half bridge gate drive board that allows simple evaluation of the performance of the ADuM4146 when driving advanced Wolfspeed third generation C3M™ silicon carbide (SiC) metal-oxide semiconductor field-effect transistors (MOSFETs) and power modules. The EVALADuM4146WHB1Z is intended to be used in conjunction with Wolfspeed clamped inductive load (CIL) test boards or half bridge evaluation boards and differential transceiver boards. The EVAL-ADuM4146WHB1Z 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-ADuM4146WHB1Z uses RS-422 signalling for improved noise and disturbance immunity and includes a 12 V power input for the EVALADuM4146WHB1Z.
