The EPC9167 GaN-based inverter reference design enhances motor system performance, range, precision, and torque while lowering overall system cost.

It is in stock at distributor Digi-Key.

The extremely small size of this inverter allows integration into the motor housing resulting in the low EMI, high density, and low weight.

The reference design board is a 3-phase BLDC motor drive inverter board featuring the EPC2065 eGaN FET rated at 3.6 mΩ maximum RDS(on), 80 V maximum device voltage.

This standard configuration uses single FETs for each switch position and delivers up to 20 ARMS maximum output current.

The EPC9167HCKIT is a high current configuration version of the reference design using two paralleled EPC2065 FETs per switch position to deliver up to 42 Apk (30 ARMS) maximum output current.

Applications include three phase motor drives in robotics, drones and e-monility, multiphase interleaving buck converters and full-bridge converters.
