ELM97xxxxB is CMOS voltage detector IC which consists of very-low-power-consumption reference voltage

source, comparator, output driver, hysteresis circuit and detection voltage setting resistor. Because of positive

logic output, the output becomes low level when Vdd is lower than detection voltage. There are 2 types of

output style of ELM97 series: N-ch opendrain and CMOS output. ELM97 series can be made as semi-custom

IC within the range of 0.9V to 5.5V(N-ch) and 1.6V to 5.5V(CMOS) by 0.1V step.
