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.
