DRV8412DDWR

Product Summary

The DRV8412DDWR is a Dual Full Bridge PWM Motor Driver. Because of the low RDS(on) of the H-Bridge MOSFETs and intelligent gate drive design, the efficiency of the motor driver can be up to 97%, which enables the use of smaller power supplies and heatsinks, and are good candidates for energy efficient applications. The DRV8412DDWR requires two power supplies, one at 12 V for GVDD and VDD, and another up to 50 V for PVDD. The applications of the DRV8412DDWR include Brushed DC and Stepper Motors, Three Phase Permanent Magnet Synchronous Motors, Robotic and Haptic Control System, Actuators and Pumps, Precision Instruments, TEC Drivers.
