• Description: Linear Vibrator Driver IC
• Manufacturer: SANYO [Sanyo Semicon Device]

Timing chart
Motor drive timing
time, driving power and Brake time can be modified by I
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
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.
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.
The Motor is driven by EN pin, and the driving time is controlled by keeping EN pin “H”. The High speed start UP
The Stand-by mode is controlled by RSTB pin. (RSTB=”L”  Stand-by mode is ON.)
