* When using the voltage V1 adjustment internal resistors or the electronic potentiometer
function, it is necessary to set at least the voltage adjustment circuit and the voltage follower
circuits both in the operating state using the power control setting command. Also, when the
voltage multiplier circuit is OFF, it is necessary to supply a voltage externally to the VOUT pin.
* The pin VR is effective only when the voltage V1 adjustment internal resistors are not used (pin
IRS = "L"). Leave this pin open when the voltage V1 adjustment internal resistors are being
used (pin IRS = "H").
* Since the input impedance of the pin VR is high, it is necessary to take noise countermeasures
such as using short wiring length or a shielded wire .
LCD Drive voltage generator circuits
The voltage V1 is divided using resistors inside the IC to generate the voltages V2, V3, V4, and
V5 that are necessary for driving the LCD. In addition, these voltages V2, V3, V4, and V5 are
impedance transformed using voltage follower circuits and fed to the LCD drive circuits. The
bias ratio of 1/9 or 1/7 can be selected in the ML9050 and the bias ratio of 1/8 or 1/6 can be
selected in the ML9051, using the LCD bias setting command.
High power mode
The power supply circuit incorporated in the ML9050/9051 has an extremely low power
consumption.
[Normal mode:
HPM
= "H"]. Hence, in the case of an LCD device or panel with a large load, the
display quality may become poorer. In such a case, setting the
HPM
pin to "L" (high power mode)
can improve the quality of display. It is recommended to verify the display using an actual unit
in order to decide whether or not to use this mode. Further, if the degree of display quality
improvement is still not sufficient even after setting the high power mode, it is necessary to
supply the LCD drive power supply from an external source.
Command sequence for shutting off the internal power supply
When shutting off the internal power supply, it is recommended to use the procedure given in
Fig. 11 of switching OFF the power after putting the LSI in the power save mode using the
following command sequence.
