Overview
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.
Functions
• Automatic adjustment to the individual resonance frequency
• Automatic brake function
• Initial drive frequency adjustment function
• Drive voltage adjustment with I²C IF setting
• Various drive pattern with I²C* IF setting (1.8V IF is available) • Low driving noise
• Low power consumption by highly effective drive (100degree drive)
Applications
• Linear Vibrator (Vibration and haptics)
• Portable Game
• Mobile Phone
• Mobile equipment with haptics function
