DRV8432 12A 双路刷式直流或单路双极步进电机驱动器（PWM 控制器）
The DRV8412/32 are high performance, integrated dual full bridge motor drivers 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%, which enables the use of smaller power supplies and heatsinks, and are good candidates for energy efficient applications.
The DRV8412/32 require two power supplies, one at 12 V for GVDD and VDD, and another up to 50 V for PVDD. The DRV8412/32 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
