BMR-0201I

System Reset IC KODENSHI BMR-0201 BMR–0201 is the low reset type of IC that guarantee to set 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. Threshold operating voltage of BMR–0201 is reduced 0.65V lower than BMR–0101 and a comparator type of hysteresis transistor developed by KODENSHI is built in the IC,so that BMR–0201 is very cost effective components. DIMENSIONS (Unit : mm) FEATURES •Low current consumption •Low operation voltage •High current of output transistor •Hysteresis circuit built in APPLICATIONS •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 MAXIMUM RATINGS Item Supply voltage Power dissipation Operating temp.
