Description
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 reduce motor stop time, and acts as an enable pin to engage micro-power sleep mode to reduce average power consumption when not in use. The A1448 is designed for use in vibration motor applications in portable devices that require fast stop-start cycles, such as haptic applications and vibration ring tones.
