System Reset IC
KODENSHI
BMR-0201
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 equipments.
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.
