HX8609A
240 Channel TFT Gate Driver with Internal Power IC
• Power-supply voltage for liquid crystal(LC) driving
 DDVDH – GND = 4.0 ~ 5.5 (V) (Driving for source driver liquid crystal output circuit
/ Driving for Vcom output)
 VGH – GND = 9.0 ~ 16.5 (V) (Driving for gate driver)
 VGL – GND = -4.0~ -14.0 (V) (Driving for gate driver)
 VCL – GND = 0 ~ -3.3 (V) (Driving for VcomL , VcomL2 output)
• Output voltage level
 VDH – GND = 3.0 ~ (DDVDH-0.5) (V) (Reference power supply for source driver grayscale
voltages)
 Vcom(2) – GND (Using for common voltage level)
 VcomH(2) = 3.0 ~ (DDVDH-0.5) (V) (High-level common voltage in alternating driving)
 Vcom L(2) = VCL + 0.5 ~ 1.0 (V) (Low-level common voltage in alternating driving)
 Vcom(2) amplitude ( VcomH(2)-VcomL(2) ) = 6 (V) max.
• Internal step-up circuit output
 DDVDH :VciOUT × 2
 VGH
:VciOUT × 6
 VGL
:VciOUT × -4 , -5
 VCL
:VciOUT × -1
