EPC91126 – 50 ARMS 3-Phase BLDC Motor Drive Inverter Evaluation Board
The EPC91126 evaluation board is a 3-phase BLDC motor drive inverter featuring the EPC2375 eGaN® FET (0.9 mΩ typical RDS(on), 100 V). It delivers up to 50 Apk (35 ARMS) continuous and 70 Apk (50 RMS) maximum output current, with PWM switching frequencies up to 100 kHz. It integrates gate drivers, auxiliary power supplies, phase current and voltage sensing, temperature monitoring, and a controller interface.
The EPC91126 includes:
One (1) EPC91126 evaluation board
One (1) EPC9147E controller board
