DRV8432DKDR

The DRV841x2 are high-performance, integrated dual
full-bridge motor driver with an advanced protection
system.
Because of the low RDS(on) of the H-Bridge MOSFETs
and intelligent gate drive design, the efficiency of
these motor drivers can be up to 97%. This high
efficiency enables the use of smaller power supplies
and heatsinks, and the devices are good candidates
for energy-efficient applications.
The DRV841x2 requires two power supplies, one at
12V for GVDD and VDD, and another up to 50 V for
PVDD. The DRV841x2 can operate at up to 500kHz
switching frequency while still maintaining precise
control and high efficiency. The devices also have an
innovative protection system safeguarding the device
against a wide range of fault conditions that could
damage the system. These safeguards are shortcircuit protection, overcurrent protection, undervoltage
protection, and two-stage thermal protection. The
DRV841x2 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 DRV841x2 has unique independent supply and
ground pins for each half-bridge. These pins make
it possible to provide current measurement through
external shunt resistor and support multiple motors
with different power supply voltage requirements.
