DRV8312 具有浪涌电流保护功能的 6.5A 三相无刷直流电机驱动器(PWM 控制器)

The DRV8312/32 are high performance, integrated three phase 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%, which enables the use of smaller power supplies and heatsinks, and are good candidates for energy efficient applications.

The DRV8312/32 require two power supplies, one at 12 V for GVDD and VDD, and another up to 50 V for PVDD. The DRV8312/32 can operate at up to 500-kHz switching frequency while still maintain precise control and high efficiency. They also have an innovative protection system safeguarding the device against a wide range of fault conditions that could damage the system
