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 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

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.
