DIMENSIONS
B M –R 0201 is the low reset type of IC that guarantee to set
again micro computers or logic s ys tems by detecting the
intermittent of fluctuating power supply voltage during
normal use or switching on/off of the equipments.
(Unit : mm)
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
B M –R 0201 is very cost effective components.
FEATURES
• Low current consumption
• Low operation voltage
• High current of output transistor
• Hysteresis circuit built in
APPLICATIONS
• Micro computer circuits in mobile phones,word
processors,TVs,VCRs etc.
• General logic circuits
• Detection of voltage drop in batteries of note personal
computers,mobile phones
• Switching to backup power supply
