B M R0401 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 BMR0401 is very cost
effective components.Constant current load built in no need to
apply Pullup resistor.
