The SED1600 is a dot matrix LCD segment (column) driver for driving a high-capacity LCD panel at duty cycles higher than 1/100 (up to 1/300). The LSI has a wide range of LCD driving voltages. Due to the architecture of the SED1600, the LCD driving voltage, V0, is isolated from the VDD supply. This provides the ability to adjust the offset bias independently of VDD. These unique features allow the SED1600 to interface with a variety of LCD panels. The SED1600 does not require a controller to output an enable signal to implement daisy chain technology. This provides for easy interfacing with the LCD controllers such as the SED1330, SED1351, SED1335, or the SED1341.

The SED1600 is used in conjunction with the SED1610 (86-row driver), SED1630 (68-bit row driver),SED1631 (100-row driver), SED1632 (86-bit row driver), SED1633 (100-bit row driver), and SED1634 (100-bit driver) to drive a large-capacity dot matrix LCD panel.
