DESCRIPTION
The DRV8332 is a high performance, integrated three phase motor driver with an advanced protection system.
Because of the low R_DS(on) of the power MOSFETs and intelligent gate drive design, the efficiency of this motor
driver can be up to 97%, which enables the use of smaller power supplies and heatsinks, and is a good
candidate for energy efficient applications.
