S71xxLSF S e m i c o n d u c t o r

Bipolar Linear Integrated Circuit Description

? Micro computer circuits in mobile phones, word processors, TVs, VCRs etc

? General logic circuits

? Detection of voltage drop in batteries of note personal computers, mobile phones

? Switching to backup power supply

Features

? Super Low Current Consumption (I CCL=100§? Typ. I CCH=1§? Typ.)

? It has on delay function to supplement the constant of outer C and R

? Low operation voltage ? High current of output transistor

? Hysteresis circuit built in ? Low operation voltage
