The DRV841x2 are high-performance, integrated dual full-bridge motor driver with an advanced protection system.

Because of the low R_DS(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 12 V for GVDD and VDD, and another up to 50 V for PVDD. The DRV841x2 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 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.
