DESCRIPTION (CONTINUED)
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.
