LC898300XA: Linear Vibrator Driver

Product Description
LC898300XA is a Linear Vibrator Driver IC for a haptics and a vibrator installed in mobile equipments. The best feature is it can adjust the drive frequency to the resonance frequency of the linear vibrator automatically without external parts. As a result, the vibration power is not influenced by the difference of the resonance frequency and it is not necessary to care about the shift of resonance frequency with the lapse of time or the impact of fall. And it is possible to improve the brake performance with the automatic brake function. Moreover, it is possible to reduce the power consumption by highly effective drive.
