DESCRIPTION VOLTAGE DETECTOR ELM 97xxxx A Series is a CMOS voltage detector IC for battery-operated portable devices. It consists of a very low-power-consumption reference voltage source, a parator, 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 microputer-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. 1.0 μ A (VDD = 1.5V) : Reset operation assured at 0.8V : ± 2.5% : TYP. -300ppm/℃ (Detection voltage ＜ 2.0V) : TYP. -100ppm/℃ (Detection voltage ≧ 2.0V) : SOT-89, SOT-23 - APPLICATION - Reset for microputer - Battery checker - Power failure detector - Switching of back-up power source - PIN CONFIGURATION SOT-89 SOT-23 1 2 3 1 2 ( TOP VIEW ) ( TOP VIEW ) Pin No. 1 2 3 Pin Name OUT VDD VSS Pin No. 1 2 3 Pin Name OUT VSS VDD VOLTAGE DETECTOR ELM97xxxx A - SELECTION GUIDE Symbol Ex a, b Detection Voltage C: N: A: B: A: 09 : VDETN = 0.9V 27 : VDETN = 2.7V 45 : VDETN = 4.5V CMOS Output N-ch Opendrain Output SOT-89 SOT-23 A Version ELM97 x x x x A ↑↑↑↑↑ a b c d e c d e Output Form Package Product Version - SERIES Detection Output Voltage Form ELM9709NBA-S(N) 0.9V N-ch ELM9710NBA-S(N) 1.0V N-ch ELM9711NBA-S(N) 1.1V N-ch ELM9722CAA-S(N) 2.2V CMOS ELM9724CAA-S(N) 2.4V CMOS ELM9725CAA-S(N) 2.5V CMOS S type : Standard, N type : Reverse Model Package SOT-23 SOT-23 SOT-23 SOT-89 SOT-89 SOT-89 Model ELM9727CAA-S(N) ELM9730CAA-S(N) ELM9732CAA-S(N) ELM9734CAA-S(N) ELM9745CAA-S(N) ELM9748CAA-S(N) Detection Voltage 2.7V 3.0V 3.2V 3.4V...
