It incorporates a voltage supply for a µC, a bridge driver for a B6 configuration, an application typical PWM interface and some other smaller features. Target is to reduce the number of discrete components in typical BLDC automotive applications and give enough flexibility for custom specific adaptations. It works with 3-phase motors and brush DC motors. Its exposed pad package allows the usage even at high ambient temperatures.
