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

LC898300XA
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 th e cen ter of resonance frequency of th e lin ear v ibrators, wh en th e i nitial d riving frequ ency is inad equate. Th e
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” Æ 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) Æ (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.

Note) When SDA&SCL signal voltages are different from VDD, even if the RSTB pin is set to Low, the IO leak current flows.
ex) In case of VDD=3.0V & SDA=SCL=1.8V, the current consumption is about 100μA(typ).
2) Case-2: Without standby-control
Note) In case of VDD=3.0V, the current consumption is about 1.5mA(typ).
