Linear Vibrator Driver IC
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

Timing chart
Motor drive timing
The Motor is driven by EN pin, and the driving time is controlled by keeping EN pin “H”. The High speed start UP
time, driving power and Brake time can be modified by I2C setting. The initial driving frequency must be set by I2C I/F
at the center of resonance frequency of the linear vibrators, when the initial driving frequency is inadequate. The
minimum width of EN signal must be larger than the cycle of initial driving frequency setting.

Stand-by Control
The Stand-by mode is controlled by RSTB pin. (RSTB=”L”  Stand-by mode is ON.)
When the stand-by mode is “ON”, the register value is set to initial value. So, the register must be set again after the
stand-by mode is “OFF”. And, the “EN” signal and I2C command must wait over 200us after “RSTB” pin is set to “H”.

EN Control
The width of EN=High should be set at least 1 driving cycle.
ex) 0x02 RESOFRQ=0x0A (175Hz)  (min) 5.71ms
The width of EN=Low should be kept over 30ms, if the pre-driving period is over 30ms. On the other hand,
If the pre-driving period is less than 30ms, the minimum width of EN=Low is same as the pre-driving width.

I C Serial Interface
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 received, the flag “ACK=L” is replied. Next, after the 8bit write data is received, the 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.
