A1448 Description
A1448 Low-Voltage, Full-Bridge Brushless DC Motor Driver with Integrated Hall Sensor IC, PWM Speed Control, Soft-Switching, and Reverse Battery and Sh.A1448 Features
* ▪ Low-voltage operation, 1.8 to 4.2 V ▪ Multifunction CONTROL pin input: ▫ Direct input PWM for speed control ▫ Active braking for fast stop cycle ▫ Sleep function to reduce average power consumption ▪ Reverse voltage protection on VDD and CONTROL pins ▪ Output thermal shutdown protection for robustA1448 Applications
* in portable devices that require fast stop-start cycles, such as haptic applications and vibration ring tones. Commutation of the motor is achieved by use of a single Hall element to detect the rotational position of an alternating-pole ring magnet. A high density CMOS semiconductor process allows t
