| System Reset IC BMR-0301 DIMENS BMR (c)0301 is the low reset type of IC that guarantee to set againmicro IONS 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(c)0301 is very cost effective components. And,BMR(c)0301 is a super(c)low consumption electric current system reset IC which has been developed with using high resistance process. FEATURES U uper S (c)low current consumption ULow operation voltage UHigh current of output transistor UHysteresis circuit built in UIt has on delay function to supplement the constant of outer C and R (Unit : mm) UMicro computer circuits in mobile phones,word processors, TVs,VCRs etc. UGeneral logic circuits UDetection of voltage drop in batteries of note personal computers mobile phones USwitching to backup power supply APPLICATIONS MAXIMUM RATINGS Item Supply voltage Power dissipation Operating temp.
