DRV8412/32 - Dual Full Bridge PWM Motor Driver

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 supports up to 52.5 V and 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.
