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.
