Linear Vibrator Driver IC
http://onsemi.com
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

LC898300XA
Writing format (Sequential Writing is possible)
After the start condition, slave address (7bit) and “L”(Write mode) are received , the flag “ACK=L” is replied. Next,
after the 8bit address is recei ved, the fla g “ACK=L” is re plied. Next, after the 8bit write data is received, t he flag
“ACK=L” is replied. Next, when the stop condition is received, the write data can be written in the specified address.
Moreover, it is possible to write data in the incremental address by the continuous input of the 8bit data confirming the
flag “ACK=L” after the every 8bit write data input.

Reading format (Sequential Reading is possible)
After the dummy writing, the start condition, slave address (7bit) and “H”(Read mode) are received, the flag “ACK=L”
is replied. Next, the 8bit read data is output. After them, when the stop condition is not received, and the read condition
is con tinued, th e read d ata of in cremental address is ou tput one by one. Th e read con dition is end when t he en d
condition is received after the flag “ACK=H”.
