Applications
LCD Monitor Panel LCD TV panel General Description The G2581 is a 9-channel level shifter suitable for TFT-LCD row drivers. This device will level shift a dig- ital input signal to an output voltage nearly equal to its output supply voltage. The G2581 has 3 supplies: VIN, VGH and VGL1. VIN is low voltage supply with a voltage range from 2.6V to 5.5V. VGH is positive high voltage supply with a volt- age range from 7V to 40V. VGL1 is negative high voltage supply with a voltage range from 0V to -30V. CKO_1~CKO_6 are level shifter outputs with gate shading function. STO and LCO_1~LCO_2 are level shifter outputs without gate shading function. The G2581 features extensive protection functions that include UVLO, OTP. This device operates over the temperature range from -40°C to +85°C. The G2581 is available in a 5mmx5mm, 32-lead QFN package.
