Description
The FAH4830 is a high-performance enhanced haptic drive for mobile phone and other hand-held devices. The haptic driver takes a single-ended PWM input signal to control a DC motor. It can drive both Eccentric Rotating Mass (ERM) and Linear Resonant Actuator (LRA) motors. The device utilizes an external 10 kH- to 50 kH- PWM signal capable of meeting the wide rang.
