The 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 EVAL[1]ADuM4146WHB1Z 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 uses the ADuM4146 High voltage, single channel, 4A, gate driver with 100kV/usec CMTI, input and output UVLO, TSD, desat detect, miller clamp, 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 signaling for improved noise and disturbance immunity and includes a 12 V power input for the EVAL-ADuM4146WHB1Z.
Features
Optimized for use with Wolfspeed SiC MOSFETs and power modules
Compatible with Wolfspeed CIL test boards and half bridge evaluation boards
High frequency, ultrafast switching operation
Input and output side UVLO
Short-circuit protection
Shoot-through protection interlock
Internal Miller clamp
Differential inputs for increased noise immunity
Isolated NTC thermistor measurement
