DRV8312DDWR Datasheet PDF - TI

●DESCRIPTION

●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.
