3 Description
The DRV83x2 are high-performance, integrated threephase
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%. This high
efficiency the use of smaller power supplies and
heatsinks, and the devices are good candidates for
energy-efficient applications.
The DRV83x2 require two power supplies, one at
12 V for GVDD and VDD, and another up to 50 V
for PVDD. The DRV83x2 can operate at up to 500-
kHz 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
DRV83x2 have 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 DRV83x2 have 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 half bridge drivers
with different power supply voltage requirements.
