Built-In Dtction Voltag Hystrsis. Thr Output Typs: N-ch, P-ch and CMOS. Spac Saving Packags: TO-9, SOT-89, SOT- and SOT-. APPLICATIONS Battry Chckr for Battry-Opratd Systms. CPU & Logic Circuit Rst. Mmory Back-up Circuit. Lvl Discriminator. Powr Failur Dtctor. DESCRIPTION Th is an accurat, ultra-low powr consumption voltag dtctor IC, fabricatd with advancd CMOS procss. Th consists of a comparator, a voltag rfrnc unit, a rsistor dividr, two output drivrs, and a hystrsis circuit. Th consumption currnt is so low that it can oftn b ignord whn compard to th battry slf-discharg currnt. Th valus of dtction and hystrsis voltag ar st intrnally and ar accuratly controlld by trimming tchniqus. Thr ar thr typs of output: N-ch opn-drain, P-ch opn-drain, and CMOS. Four typs of packag, TO-9, SOT-89, SOT- and SOT--, ar availabl to sav board spac.
