SSD1730 MLA Power Chip

CMOS

1. 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.

2. 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)
