GENERAL DESCRIPTION
The SSD1730 is a power chip for operating four-line MLA (Multi Line Addressing) LCD drivers. It consists of a CMOS charge pump-type voltage converter that can generate all the bias voltages required for the four-line MLA drive based on a single power supply input.
This can be used for the system that is formed by a column (segment) driver such as SSD1870 and a row (common) driver such as SSD1881. Such type of display system is able to produce a module with lower power consumption when comparing with the conventional driving method.

FEATURES
▪ Single Power Supply Operation, +2.4V to +3.6V
▪ Low current consumption
▪ Two step-up modes, 5X or 6X step-up by internal charge pump DC/DC converter
▪ Internal LCD voltage generator to generate all LCD voltages required for 4-line MLA driving
▪ External contrast control
▪ Internal –V1 discharge circuit to discharge the residual charge at the row driver negative
   voltage-side power supply voltage terminal –V1
▪ Internal “power off” function using an external signal
▪ Equipped internally with a LCD polarity reverse signal generator
▪ Polarity reversed period in the range of 2P to 17P
▪ Available in 48 pin QFP package (0.5 mm terminal pitch)
