Fairchild Semiconductor FAH4840 Haptic Driver

Fairchild Semiconductor's FAH4840 Haptic Driver delivers a high-performance motor driver for mobile phones and other hand-held devices. The haptic driver takes a single-ended PWM input signal to control a Linear Resonant Actuator (LRA). The device utilizes an external 10 kHz to 250 kHz PWM signal capable of meeting the wide range of resonant frequencies needed for an LRA haptics applications. The FAH4840 register map is accessible through an I2C serial communication port.
