ELM97xxxxA 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. 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 microcomputer ・ Battery checker ・ Power failure detector ・ Switching of back-up power source ■ PIN CONFIGURATION SOT-89 3 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 147 VOLTAGE DETECTOR ELM97xxxxA ■ 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 ↑↑↑↑↑ abcde 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 4.5V 4.8V Output Form CMOS CMOS CMOS CMOS CMOS CMOS Package SOT-89 SOT-89 SOT-89 SOT-89 SOT-89 SOT-89 * Available 0.9V～5.0V detection voltage for N-ch output and 2.0V～5.0V detection voltage for CMOS output at 0.1V step as semi-custom-made IC. 148 VOLTAGE DETECTOR ELM97xxxxA ■ MARKING SOT-89 Rule 1 ① : Represents the integer digit of the detection voltage Symbol A B C D E F Detection Voltage 0.*V (N-ch) 1.*V (N-ch) 2.*V (N-ch) 3.*V (N-ch) 4.*V (N-ch) 5.*V (N-ch) Symbol P R S T Detection Voltage 2.*V (CMOS) 3.*V (CMOS) 4.*V (CMOS) 5.*V (CMOS) ① ② ③ ④ ② : Represents the decimal digit of the detection voltage SOT-23 Symbol 0 1 Detection Voltage *.0V *.1V *.2V *.3V *.4V Symbol 5 6 7 8 9 Detection Voltage *.5V *.6V *.7V *.8V *.9V ①②③④ 2 3 4 ③ : Represents the assembly lot number A ～ Z repeated (I,O,X excepted) ④ : Represents the assembly lot number 0 ～ 9 repeated Rule 2 ① : Represents the ELM97xxxxA series ELM97xxxxA series = A ② : Represents the integer digit of the detection voltage Symbol 0 1 2 3 4 5 Symbol 0 1 2 3 4 Detection Voltage 0.*V (N-ch) 1.*V (N-ch) 2.*V (N-ch) 3.*V (N-ch) 4.*V (N-ch) 5.*V (N-ch) Detection Voltage *.0V *.1V *.2V *.3V *.4V Symbol Y W U V Detection Voltage 2.*V (CMOS) 3.*V (CMOS) 4.*V (CMOS) 5.*V (CMOS) ③ : Represents the decimal digit of the detection voltage Symbol 5 6 7 8 9 Detection Voltage *.5V *.6V *.7V *.8V *.9V ④ : Represents the assembly lot number 0 ～ 9, A ～ Z repeated (I,O,X excepted) *Remarks --- ELM97xxxxA series have two kind of mraking rules each package. 149 VOLTAGE DETECTOR ELM97xxxxA ■ BLOCK DIAGRAM 1.CMOS Output VDD VREF + VDD VREF OUT + - 2.N-ch Opendrain Output OUT VSS VSS ■ TIMING CHART VDD VDETP VDETN VopMin VSS OUT VHYS VSS tPHL tPLH ■ MAXIMUM ABSOLUTE RATINGS Parameter Power Supply Voltage Output Voltage Output Current Power Dissipation Operating Temperature Storage Temperature Symbol VDD CMOS VOUT N-ch IOUT SOT-89 Pd SOT-23 Top Tstg Limits 10 VSS-0.3～VDD+0.3 VSS-0.3～+10 50 300 200 -30～+80 -40～+125 (VSS=0V) Units V V mA mW ℃ 150 VOLTAGE DETECTOR ELM97xxxxA ■ ELECTRICAL CHARACTERISTICS ELM9709NBA Parameter Detection Voltage Hysteresis width Current Consumption Operating Voltage Output Current Delay Time Temperature Characteristics of VDETN Symbol VDETN VHYS ISS VDD IOUTN tPHL △VDETN △Top Conditions Min.
