Supply
Power supply(Logic)
Internal regulator power supply
This pin is connected to VDD.
Regulated power supply input pin for internal digital and DDRAM block.
This pin is connected to REG_OUT outside the chip with stabilization capacitor.
When the internal regulator is not used, VDD1 should be tied to VDD directly.
GND Ground
I LCD common high selected driving voltage input pin
I LCD segment high selected driving voltage input pin
I LCD common/segment non-selected driving voltage input pin
I LCD segment low selected driving voltage input pin
LCD common low selected driving voltage input pin
I The relationship between VCC, V1, VM, V0 and VEE:
VCC > V1 > VM > V0(=VSS) > VEE (V1 – VM = VM – V0, VCC –VM = VM – VEE)
I Power supply for 1’st booster circuit and VM amp
I Power supply for 2’nd booster circuit
O 1’st booster output pin
I Power supply for V1. Connect to VOUT45 or VIN1
O External capacitor connection pins used for 1’st booster circuit
O LCD segment high driving voltage output pin
I Thermistor resistor connection pin
I
External resister select pin for temperature compensation circuit
– INTRS = L : External resistor mode, INTRS = H : Internal resistor mode
O LCD common/segment non-selected driving voltage output pin
O Power output pin for 2’nd booster input
I Power supply for 2’nd booster. Connect to DC2OUT pin
O External capacitor connection pins used for 2’nd booster circuit
O LCD common low selected driving voltage output pin
O External capacitor connection pins used for 3’rd booster circuit
O LCD common high selected driving voltage output pin
