Picture cell driver for STN (LCD driver) for low voltage power supplies
The BU9718KV is a driver IC designed for the character-type STN liquid crystal panels which are ideal for applications such as portable devices. The number of display segments includes 32 output segments and 3 common outputs, enabling drive of up to 96 segments. A compact 48-pin QFP package with a pitch of 0.5 mm is used, enabling compact size for the set as a whole.
FEATUREs
1) Operates on 3V power supply.
2) Low current dissipation. (0.1µA in low power mode (actual value))
3) Compact package. (molded section is 7.0 mmu)
4) Up to 32 segment output pins and 3 common output pins are provided, enabling a total display of up to 96 segments.
5) 1 / 3 duty display.
6) Either 1 / 2 or 1 / 3 bias can be selected for power supply for LCD display.
APPLICATIONs
Portable terminals (POS, ECR, PDA, and others), movie projectors, cameras, telephones (cordless handheld telephone units), and others Low-voltage power supply sets
