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. 1.0 μ 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
