M5003

MOSDESIGN SEMICONDUCTOR CORP. EL CONTROLE M5003 EL LAMP DRIVER IC GENERAL DESCRIPTION The M5003 is CMOS chip design for Electro-luminescence Lamp (EL) to light has independent circuit to control switching and EL driver frequency circuit, The switching frequency is decided by CKX, If OSC connect a resistor to VDD, or connect a capacitor to VSS the switching frequency can be adjusted. Delay function can be implement if ON connect a capacitor to VSS. The time of delay is decided by the value of capacitor. FEATURES DC to AC conversion Built-in RC oscillator Two trigger inputs TG : active High TGB : active Low Adjustable EL driver frequency by CKX Adjustable Switching frequency by CHOPX APPLICATIONS EL display BLOCK DIAGRAM OSC Oscillator CKX Divider Inductor Driver CHOP CHOPX Oscillator ON Oscillator Delay Time Divider EL Driver CK TGB TG S1 S2 Control Logic *All specs and applications shown above subject to change without prior notice.
