7. Precaution
Be careful when connecting or disconnecting the power
This LSI has a high-voltage LCD driver, so it may be permanently damaged by a high current, which may occar, if a voltage is
supplied to the LCD driver power supply while the logic system power supply is floating.
The details are as follows:
!
When connecting the power supply, connect the LCD driver power after connecting the logic system power. Furthermore,
when disconnecting the power, disconnect the logic system power after disconnecting the LCD driver power.
We recommend that you connect a serial resistor (50-100
) or fuse to the LCD driver power V
0
of the system as a current
limiting device. Also, set a suitable value of the resistor in consideration of LCD display grade.
!
In addition, when connecting the logic power supply, the logic condition of this LSI inside is insecure. Therefore connect the
LCD driver power supply after resetting the logic condition of this LSI inside to DISPOFF function. After that, the
DISPOFFcancel the function after the LCD driver power supply has become stable. Furthermore, when disconnecting the
power, set the LCD driver output pins to level V
5
on the DISPOFF function. After that, disconnect the logic system power after
disconnecting the LCD driver power.
When connecting the power supply, follow the recommended sequence shown.
