ELM9722CAA-S fiche technique
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
