A1448 Low-Voltage Full-Bridge Brushless DC Motor Driver

The A1448 is a full-bridge motor driver designed to drive low-voltage, brushless DC motors. The device is designed to allow the user to control several functions with a single input control pin. The pin allows for direct input PWM for speed control, is used to initiate the active braking function to.
