| MA88V11B EL DRIVER Line-up & Specification V1.0 MosArt SEMICONDUCTOR CORP. 2000 All rights reserved MosArt BONDING DIAGRAM MA88V11B EL DRIVER EL IND VDD VSS OSC SELF EN Chip size : 808um * 665um Pad size : 90um * 90um FEATURES 3V battery operation No external R-C required for oscillation Two EL driving frequency can be selected to change the colors of EL lights 3 seconds delay after EN released OVERVIEW The MA88V11B is designed for driving EL on watch's back light. The operating voltage is 3V. An inductor is used to generate the high voltage, and one diode, 2 transistors and a resistor are necessary. The EL deriving frequency can be selected for changing the color of EL lights. MA88V11B can be selected for normal trigger or delay 3 seconds. MosArt Semiconductor Corp.
