System Reset IC
KODENSHI
BMR-0302
BMR鈥?302 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
theequipments.
A comparator type of hysteresis transistor developed by KODENSHI is
built in the IC,so that BMR鈥?302 is very cost effective components.
And,BMR鈥?302 is a super鈥搇ow consumption electric current system
reset IC which has been developed with using high resistance process.
FEATURES
鈥uper low current consumption
鈥?/div>
鈥ow operation voltage

鈥ysteresis circuit built in
鈥t has on delay function to supplement the constant of outer C and R
鈥 package is SOT鈥?3 of the super鈥搈iniature surface mounting type
APPLICATIONS
鈥icro computer circuits in mobile phones,word processors,TVs,VCRs
etc.
鈥eneral logic circuits
鈥etection of voltage drop in batteries of note personal computers,
mobile phones
鈥witching to backup power supply
