BMR-0401G

System Reset IC KODENSHI BMR-0401 BMR–0401 is the low reset type of IC that guarantee to set DIMENSIONS 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–0401 is very cost effective components.Constant current load built in no need to apply Pull–up resistor. (Unit : mm) FEATURES •Low current consumption •Low operation voltage •High current of output transistor •Hysteresis circuit built in •Constant current load 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.
