FAH4830MPX

FAH4830 Haptic Driver for DC Motors (ERMs) and Linear Resonant Actuators (LRAs) Features Description           Direct Drive of ERM and LRA Motors 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 kHz to 50 kHz PWM signal capable of meeting the wide range of resonant frequencies.   Settable Filter and External Gain Control External PWM Input (10 kHz to 50 kHz) External Motor Enable/Disable Input Internal Mode-Select Register: ERM or LRA Low Standby Current:
