Description

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 short

circuit 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.
