FAH4840

Haptic Driver for Linear Resonant Actuators (LRAs)

Description

Features

The FAH4840 is a high-performance amplifier 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.
