The DRV8312/32 are high performance, integrated three phase motor drivers with an advanced
protection system. Because of the low RDS(on) of the power MOSFETs and intelligent gate drive design, the efficiency of these motor drivers can be up to 97%, which enables the use of smaller power supplies and heatsinks, and are good candidates for energy efficient applications.
