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 equip-
ments.
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.
