LC898301AXA: Liner Vibrator Driver
The LC898301AXA is a Linear Vibrator Driver dedicated to haptic feedback actuator and vibrator employed in mobile equipment. Due to the product superior technology, the drive frequency is automatically adjusted to the resonance frequency of the linear vibrator without the use of other external parts. As a result of this very effective drive, the vibration is as powerful as possible using very limited amount of energy compared to classical solutions. The start time and brake time are fully configurable through the I2C setting. Moreover, an automatic braking function has been implemented allowing to optimize the braking time. Finally, a self test mode allows to detect various possible functional defaults during assembly.
