ELM97xxxxA
GENERAL DESCRIPTION
VOLTAGE DETECTOR
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.
