DRV8412DDW

The DRV8412DDW from Texas Instruments is a high-performance, integrated dual full-bridge motor driver designed for applications requiring precise motor control. It features a high-efficiency power stage with low RDS(on) MOSFETs, achieving up to 97% efficiency. This allows for the use of smaller power supplies and heatsinks, making it suitable for energy-efficient designs.

The device operates with supply voltages up to 52.5V and can deliver up to 6A continuous output current in parallel mode or 2 x 3A continuous current in dual full-bridge mode. Peak currents can reach 12A in parallel mode or 2 x 6A in dual full-bridge mode. The DRV8412DDW supports PWM control with operating frequencies up to 500kHz.

Integrated self-protection circuits include undervoltage lockout, overtemperature, overload, and short-circuit protection, along with programmable cycle-by-cycle current limit protection. It requires two power supplies: 12V for GVDD and VDD, and up to 50V for PVDD. The driver is housed in a 44-pin HTSSOP package and is designed for surface mounting.

This motor driver is suitable for applications involving DC motors and stepper motors, offering intelligent gate drive and cross-conduction prevention. No external snubber or Schottky diodes are required, simplifying the design.
