The DRV8312DDW is a 6.5A 3-phase brushless DC Motor Driver with inrush protection. 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 heat sinks and the devices are good candidates for energy-efficient applications. The DRV8312 require two power supplies, one at 12V for GVDD and VDD and another up to 50V for PVDD. The motor driver can operate at up to 500kHz switching frequency while still maintaining precise control and high efficiency. The device also has 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, over-current protection, under-voltage protection and two-stage thermal protection. The driver has a current-limiting circuit that prevents device shutdown during load transients such as motor start-up.
