DESCRIPTION
High Voltage Output
80-bit to 1/300 Display Duty
1/100
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 V
DD
supply. This provides the
ability to adjust the offset bias independently of V
DD
. 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.
