ELM97xxxxA ^{VOLTAGE DETECTOR}

■ GENERAL DESCRIPTION

ELM 97xxxxA Series is a CMOS voltage detector IC for battery-operated portable devices. It consists of a

very low-power-consumption reference voltage source, a comparator, an output driver, a hysteresis circuit,

and detection voltage setting resistors. Output logic is positive, therefore output level is low when VDD is

lower than detection voltage.

It can be used as a reset controller in microcomputer-based systems. And it can be widely applied to the

devices, such as battery checkers, switching circuit of back-up power source, power failure detectors, etc.

Two output styles are available, N-ch opendrain and CMOS output.

It is available in SOT-89 and SOT-23.

■ FEATURES

・ Low power operation

: TYP. 1.0μ A (VDD = 1.5V)

・ Low voltage operation

: Reset operation assured at 0.8V

・ High accuracy of detection voltage : ± 2.5%

・ Low temperature coefficient

: TYP. -300ppm/℃ (Detection voltage ＜2.0V)

: TYP. -100ppm/℃ (Detection voltage ≧2.0V)

・ Very small package

: SOT-89, SOT-23

■ APPLICATION

・ Reset for microcomputer

・ Battery checker

・ Power failure detector

・ Switching of back-up power source
