The DRV8332 is a high performance, integrated three phase motor driver with an advanced protection system.

Because of the low RDS(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.

The DRV8332 requires two power supplies, one at 12 V for GVDD and VDD, and another up to 50 V for PVDD. The DRV8332 can operate at up to 500-kHz switching frequency while still maintain precise control and high efficiency. It also has an innovative protection system safeguarding the device against a wide range of fault conditions that could damage the system. These safeguards are short-circuit protection, overcurrent protection and undervoltage protection. The DRV8332 has a current-limiting circuit that prevents device shutdown during load transients such as motor start-up. A programmable overcurrent detector allows adjustable current limit and protection level to meet different motor requirements.

The DRV8332 has unique independent supply and ground pins for each half bridge, which makes it possible to provide current measurement through external shunt resistor and support half bridge drivers with different power supply voltage requirements.
