SM8140A
EL Driver IC
OVERVIEW
The SM8140A is designed for using as EL (Elec-
tronic Luminescence) sheet driver require very low
external parts counts, this result that very compact
and thin EL driver units can be made.
Also this device has the features to use in wider
range of applications demanding low quiescent cur-
rent, low supply voltages, low operating supply cur-
rents, simple brightness control and low EMI
(Electro-Magnetic Interference) emission due to the
inherent smooth driver wave forms.
FEATURES
s Specially providing EL driver functions
s Non-transformer for compact outline
s Bipolar driving for high power efficiency
s Very low noise smooth driver wave forms
s Brightness control with driving frequency change
(An external resistance determines the driving fre-
quency)
s Low power consumption by quiescent current
control
s ON-chip high voltage output MOS transistor
s Large EL sheet (Exceeding 100 cm2) drivable
s supply voltage
VDD = 2.4V to 3.6V or 5.0V
s 1.5V and 3V power applicable
(Refer to APPLICATION HINTS)
s Maximum output driver voltage:200VP − P
s Typical driver frequency:250Hz
s 14 pin SSOP
s chip form
