Overview
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.
■ FEATURES ・ Low power operation ・ Low voltage operation ・ High accuracy of detection voltage ・ Low temperature coefficient ・ Very small package : TYP.
