SM8140A
EL Driver IC
NIPPON PRECISION CIRCUITS—1
NIPPON PRECISION CIRCUITS INC.
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
I
Specially providing EL driver functions
Non-transformer for compact outline
Bipolar driving for high power efficiency
Very low noise smooth driver wave forms
Brightness control with driving frequency change
(An external resistance determines the driving fre-
quency)
Low power consumption by quiescent current
control
ON-chip high voltage output MOS transistor
Large EL sheet (Exceeding 100 cm
