BMR-0301D

System Reset IC KODENSHI BMR-0301 BMR–0301 is the low reset type of IC that guarantee to set againmicro DIMENSIONS computers or logic systems by detecting the intermittent of fluctuating power supply voltage during normal use or switching on/off of theequipments. A comparator type of hysteresis transistor developed by KODENSHI is built in the IC,so that BMR–0301 is very cost effective components. And,BMR–0301 is a super–low consumption electric current system reset IC which has been developed with using high resistance process. (Unit : mm) FEATURES •Super low current consumption – •Low operation voltage •High current of output transistor •Hysteresis circuit built in •It has on delay function to supplement the constant of outer C and R •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 APPLICATIONS MAXIMUM RATINGS Item Supply voltage Power dissipation Operating temp.
