Description：

The DRV841x2 are high-performance, integrated dualfull-bridge motor driver with an advanced protectionsystem.Because of the low RDS(on) of the H-Bridge MOSFETsand intelligent gate drive design, the efficiency ofthese motor drivers can be up to 97%. This highefficiency enables the use of smaller power suppliesand heatsinks, and the devices are good candidatesfor energy-efficient applications.The DRV841x2 requires two power supplies, one at12 V for GVDD and VDD, and another up to 50 V forPVDD. The DRV841x2 can operate at up to 500-kHzswitching frequency while still maintaining precisecontrol and high efficiency. The devices also have aninnovative protection system safeguarding the deviceagainst a wide range of fault conditions that coulddamage the system. These safeguards are shortcircuit protection, overcurrent protection, undervoltageprotection, and two-stage thermal protection. TheDRV841x2 has a current-limiting circuit that preventsdevice shutdown during load transients such as motorstart-up. A programmable overcurrent detector allowsadjustable current limit and protection level to meetdifferent motor requirements.The DRV841x2 has unique independent supply andground pins for each half-bridge. These pins make itpossible to provide current measurement throughexternal shunt resistor and support multiple motorswith different power supply voltage requirements.
