This reference design demonstrates a three-phase inverter with nominal 48V DC input and 85Arms output current rating. The 100V intelligent half-bridge gate driver DRV8162L enables a small size, robust and high efficiency power stage. Multichannel shutdown paths using the split power supply architecture of RV8162L are proposed for the Safe Torque Off (STO) function. With the internal VDS monitor and protection feature of the DRV8162L, the power stage is protected against overcurrent failures of shoot-through or outputs short-circuit. Precision phase current sensing is achieved using the INA241A. The design offers a 3.3V I/O interface to connect a host controller like a C2000™ MCU for quick and easy evaluation.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
