OVERVIEW
The SM8144B is a transformer-less electroluminescent (EL) driver IC, capable of driving displays up to 80 cm2 in size. It is a high-efficiency driver that features revised coil switching transistor ON resistance and output circuit configuration to reduce loss, all in a compact package. A microcontroller interface pin (ENA) is provided, which can be used to control the EL driver ON/OFF function. The device is available in 8-pin VSOP packages.

■ 100mA maximum operating current
(VDD = 3.0V, Ta ≤ 70°C)
■ 3.5Ω typical output resistance
■ 200 Vp-p maximum EL driver voltage*
■ 31 to 1500 Hz EL drive frequency range*
■ High voltage CMOS Process
■ 8-pin VSOP plastic package
*: Adjustable with external resistance.


APPLICATIONS
■ Hand held PC, Palm size PC
■ Mobile IT equipment
■ White EL
