产品概述 返回TOP
The CXLC8917 series product is a poly gate CMOS integrated circuit which is designed to drive an electroluminescence Lamp (EL) to light. It supplies three pins for trigger input: one is active at low (ALM) and other two are active at high(TG&FLSH). 3 seconds display delay function is implemented by internal divider. Only ALM and TG will generate3seconds delay but FLSH not. The switching and EL driving frequency is decided by an intimae RC oscillator. Thedriving capability for IND output and frequency for EL output are different options, the detail information shown in theOPTION LIST.
CXLC8917 series product can be widely used in the back light of digital watch, analogy watch, calculator etc
