ELM97xxxxB CMOS Voltage detector
■General description
http://www.elm-tech.com
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.
■Features
• Detection voltage range
: N-ch 0.9V to 5.5V (by 0.1V)
CMOS 1.6V to 5.5V (by 0.1V)
• Low voltage operation
: Reset operation assured at 0.8V
• Low current consumption : Typ.1μA(Vdd=1.5V)
• Accuracy of detection voltage : ±2.5%
• Temperature coefficient
: Typ.-300ppm/°C(Vdetn<2V)
Typ.-100ppm/°C(Vdetn≥2V)
• Package
: SOT-89, SOT-23
■Application
