| System Reset IC K DNH OESI BMR-0401 BMR (c)0401 is the low reset type of IC that guarantee to ENSIONS set DIM again micro computers or logic systems by detecting the intermittent of fluctuating power supply voltage during normal use or switching on/off of the equipments. A comparator type of hysteresis transistor developed by KODENSHI is built in the IC,so that BMR(c)0401 is very cost effective components.Constant current load built in no need to apply Pull(c)up resistor. ULow current consumption ULow operation voltage UHigh current of output transistor UHysteresis circuit built in UConstant current load built in (Unit : mm) FEATURES APPLICATIONS 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 MAXIMUM RATINGS Item Supply voltage Power dissipation Operating temp.
