Description
The FAH4830 is 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. The haptic driver takes a single-ended PWM input signal to control a DC motor.
Features
1. Direct Drive of ERM and LRA Motors
2. External PWM Input (10 kHz to 50 kHz)
3. External Motor Enable/Disable Input
4. Internal Mode-Select Register: ERM or LRA
5. Low Standby Current: <500 nA
6. Fast Wake-up Time
7. Nearly Rail-to-Rail Output Swing
Applications:
1. Mobile Phones
2. Handheld Devices
3. Any Key-Pad Interface
