4.1 Enabling 48V BLDC Motor Drive Applications

The DRV8376 comes with a maximum operating voltage rating of 65V and absolute maximum voltage rating of 70V. The high voltage rating makes DRV8376 an excellent choice for 48V industrial and automotive applications, those typically having a maximum voltage tolerance of up to 60V. The device comes with integrated over voltage protection and that can be leveraged to place all the MOSFETs in to Hi-Z in the event of a DCvoltage more than the over voltage protection threshold.
