System Reset IC KODENSHI BMR-0302 BMR–0302 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 theequipments. A comparator type of hysteresis transistor developed by KODENSHI is built in the IC,so that BMR–0302 is very cost effective components. And,BMR–0302 is a super–low consumption electric current system reset IC which has been developed with using high resistance process.
