System Reset IC
KODENSHI
BMR-0401
BMR–0401 is the low reset type of IC that guarantee to set
DIMENSIONS
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 BMR–0401 is very cost
effective components.Constant current load built in no need to
apply Pull–up resistor.
(Unit : mm)
FEATURES

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
