System Reset IC
KODENSHI
BMR-0101
BMR–0101 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.
A comparator type of hysteresis transistor developed by
KODENSHI is built in the IC,so that BMR–0101 is very cost
effective components.
