■■

■ 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
