DIMENSIONS
B M –R 0101 is the low reset type of IC that guarantee to s et
again micro computers or logic s ys tems by detecting the
in te rm itte n t o f fluc tua tin g powe r s upply volta ge during
normal use or switching on/off of the equipments.
A c om pa ra tor type of hys te re s is tra ns is tor de ve lope d by
KODENSHI is built in the IC,so that BMR– 0101 is very cost
effective components.
