Function
I/O DC-DC converter 2 capacitor connection pins
Connect these pins to external voltage booster capacitors in order to generate negative
voltages for the T6K48. The recommended capacitance for the capacitors is 1 mF.
O DC-DC converter 2 output pin
This pin outputs the supply high-level voltage (+13 V) used for the T6K48.
I
DC-DC converter 3 supply voltage input pin
The voltage for DC-DC converter 3 used to generate a voltage on the VBOUT pin is input on
this pin. It must be connected to the VTOUT pin.
I/O DC-DC converter 3 capacitor connection pins
Connect these pins to an external voltage booster capacitor in order to generate negative
voltages for the T6K48. The recommended capacitance for the DC-DC converter capacitor is 1
mF.
O DC-DC converter 3 output pin
This pin outputs the supply low-level voltage (-13 V) used for the T6K48.
I
Standby signal input pin
The chip stays in standby state while /STB = L. Enabling the /STB pin halts all the built-in
circuits.
I
Reset signal input pin
A reset signal must be input on this pin after the power is turned on.
I
Alternating signal input pin
This POL signal inverts the phase of the COMOUT, VLC and /VLC signals. See Fig. 2 for an
explanation of how to invert the phase.
¾ g-correction power supply voltage pin
This pin outputs a voltage whose phase is under the control of the POL signal. The following
table lists the output voltages and their phases.

O Common signal output pin
This pin outputs, in phase with the POL signal, a signal whose level has been converted to the
board level necessary for the LCD.
I
DC-DC converter ON/OFF switching pin
This pin is used to turn the DC-DC converters ON/OFF. Normally it should be connected to
GND.
