SED1748

LOW-POWER 160-BIT LCD SEGMENT DRIVER

■ DESCRIPTION

The SED1748 is a 160-bit dot matrix LCD segment (column) driver for driving high-capacity LCD panels at

duty cycles higher than 1/100 (up to 1/500). The LSI features a wide range of LCD drive voltages. The upper

and lower LCD drive voltages (V0, V5) are independent of the chip supplies. This enables the LCD drive bias

voltages to be supplied from an external source. The device uses a daisy-chain enable system which

decreases power consumption and eliminates the need for separate signals for each driver.

The SED1748 is used in conjunction with the SED1743 (160-bit common driver) to drive a large-capacity dot

matrix LCD panel.
