NIPPON PRECISION CIRCUITS—1 NIPPON PRECISION CIRCUITS INC. 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

n Specially providing EL driver functions n Non-transformer for compact outline n Bipolar driving for high power efficiency n Very low noise smooth driver wave forms n Brightness control with driving frequency change (An external resistance determines the driving fre- quency) n Low power consumption by quiescent current control n ON-chip high voltage output MOS transistor n Large EL sheet (Exceeding 100 cm ) drivable n supply voltage V DD 2.4V to 3.6V or 5.0V n 1.5V and 3V power applicable (Refer to APPLICATION HINTS) n Maximum output driver voltage:200V P P n Typical driver frequency:250Hz n 14 pin SSOP n chip form ORDERING INFOMATION PIN OUT ( Top View ) PIN OUT ( Unit : mm ) Device Package SM8140AM 14pin SSOP CF8140A Chip in tray CHV LDR VSS1 OCL2 OCL1 OCE2 OCEl OUT1 OUT2 CP2 CP1 CPO VDD ENA 14pin SSOP SM8140AM 8.00 8.20 1.000.35 0.10 1.50 1.80MAX 0.10 0.10 0.625 0.20 01 0 0.17 0.20 4.40 6.40 0.30
