(1) In the initial state, an input voltage (VIN) higher than the release voltage (VDR) is applied, and VIN gradually drops. When a voltage higher than the detect voltage (VDFL) is applied to the input voltage (VIN), the output voltage (VOUT) is equal to the input voltage (VIN). *On the N-ch open drain output product, the VOUT pin is in a high impedance state, and when the output is pulled up, the output voltage (VOUT) is equal to the pull-up voltage. (2) When the input voltage (VIN) drops below the detect voltage (VDFL), the output voltage (VOUT) is equal to the ground voltage (VSS). (Detection state) *This also applies to the N-ch open drain output product. (3) If the input voltage (VIN) drops below the minimum operating voltage (0.7V), the output becomes unstable. *If the output pin on the N-ch open drain output product is pulled up, the pull-up voltage may be output as the output voltage (VOUT). (4) The output voltage (VOUT) remains at the ground voltage as the input voltage (VIN) rises past the minimum operating voltage (0.7V) and reaches the release voltage (VDR). (5) If the input voltage (VIN) rises higher than the release voltage (VDR), the output voltage (VOUT) is equal to the input voltage (VIN). *On the N-ch open drain output product, the VOUT pin is in a high impedance state, and if the output is pulled up, the pull-up voltage is output as the output voltage (VOUT) as in (1). (6) The difference between the release voltage (VDR) and the detect voltage (VDFL) is the hysteresis width (VHYS). Note: For simplicity, the above explanation omits the circuit operation time. 6/16 XC6126 Series ■NOTE ON USE 1. Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded. 2. Note that there is a possibility of malfunctioning if the input voltage changes sharply or undergoes repeated, cyclical changes. 3. If the resistance RIN is connected between the VIN pin and the power supply VDD, the voltage drop due to the flow through current in the internal circuit and RIN may cause oscillation when release takes place. When using the CMOS output product, oscillation due to RIN and the flow through current may occur without relation to release and detection, and thus RIN should not be connected. 4. Please use N-ch open drains configuration, when a resistor RIN is connected between the VIN pin and the power supply VDD. In such cases, please ensure that RIN is less than 33kΩ. Vpull-Up RIN≦33kΩ XC6126N Series VIN VDD Rpull VOUT VOUT VSS [Figure 1: Circuit connected with the input resistor fro N-ch open drain] N-chオープンドレイン品で入力抵抗を接続する場合の回路例 5. When N-ch open drain output is used, the VOUT voltage at detection is determined by the pull-up resistance connected to the output pin. Select the resistance based on the following considerations: At detection: VOUT = (Vpull-Up)/(1+Rpull/RON) Vpull-Up: Voltage after pull-up RON(*1): ON resistance of N-ch driver (calculated from VOUT/IOUT1 based on electrical characteristics) (*3) Example: When VIN = 2.0V (*2), RON = 0.5/4.5×10-3≒111Ω（MAX.）. If it is desired to make the VOUT voltage at detection 0.1V or less when Vpull-Up is 3.0 V, Rpull = (Vpull-Up /VOUT-1)×RON=(3/0.1-1)×111 ≒ 3.2kΩ Therefore, to make the output voltage at detection 0.1 V or less under the above conditions, the pull-up resistance must be 3.2kΩ or higher. (*1) Note that RON becomes larger as VIN becomes smaller. (*2) For VIN in the calculation, use the lowest value of the input voltage range you will use. (*3) IOUT1 in the electrical characteristics is at Ta = 25℃. IOUT1 varies depending on the ambient temperature. To select a pull-up resistance taking ambient temperature into account, consult us. At release: VOUT = (Vpull-Up)/(1+Rpull/ROFF) Vpull-Up: Voltage after pull-up ROFF: 40MΩ (MIN.) resistance when N-ch driver is OFF (calculated from VOUT/ILEAK based on electrical characteristics) Example: Making VOUT 5.99 V or higher when Vpull-Up is 6.0 V: Rpull = (Vpull-Up/VOUT-1)×ROFF = (6/5.99-1)×40×106 ≒ 66 kΩ Therefore, to make the output voltage at release 5.99 V or higher under the above conditions, the pull-up resistance must be 66kΩ or less. 6. Torex places an importance on improving our products and its reliability. However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment. 7/16 XC6126 Series ■TEST CIRCUITS Circuit 1 (Unused for the CMOS output products) Circuit 2 Circuit 3 Circuit 4 (Unused for the CMOS output products) Measurement of waveform 8/16 XC6126 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (1) Supply Current vs. Input Voltage (2) Supply Current vs. Ambient Temperature VDF(T)=1.5V VDF(T)=1.5V 1.4 VIN=0V→6.0V→0V 1.2 Supply Current : ISS (μA) Supply Current : ISS (μA) 1.4 1.0 0.8 0.6 -40℃ 0.4 25℃ 0.2 85℃ 0.0 0 1 2 3 4 Input Voltage : VIN (V) 5 1.2 1.0 VIN=VDFL*1.1V 0.8 0.6 0.4 0.2 0.0 -50 6 VIN=VDFL*0.9V -25 1.4 1.4 1.2 VIN=0V→6.0V→0V Supply Current : ISS (μA) Supply Current : ISS (μA) 100 VDF(T)=2.7V VDF(T)=2.7V 1.0 0.8 0.6 -40℃ 0.4 25℃ 0.2 85℃ 0 1 2 3 4 Input Voltage : VIN (V) 5 1.2 6 VIN=VDFL*0.9V 1.0 VIN=VDFL*1.1V 0.8 0.6 0.4 0.2 0.0 -50 0.0 -25 VDF(T)=5.5V 0 25 50 75 Ambient Temperature : (℃) 100 VDF(T)=5.5V 1.4 1.4 1.2 VIN=0V→6.0V→0V Supply Current : ISS (μA) Supply Current : ISS (μA) 0 25 50 75 Ambient Temperature : (℃) 1.0 0.8 0.6 0.4 -40℃ 25℃ 0.2 1.2 1.0 0.8 0.6 VIN=VDFL*0.9V 0.4 VIN=6.0V 0.2 85℃ 0.0 0 1 2 3 4 Input Voltage : VIN (V) 5 6 0.0 -50 -25 0 25 50 75 Ambient Temperature : (℃) 100 9/16 XC6126 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (3) Output Voltage vs. Input Voltage1 (4) Detect Voltage, Release Voltage vs. Ambient Temperature VDF(T)=1.5V VDF(T)=1.5V VIN=1.4V～1.8V 1.8 Detect Voltage, Release Voltage : VDFL, VDR (V) 1.8 Output Voltage : VOUT(V) 1.6 1.4 1.2 1.0 0.8 -40℃ 0.6 25℃ 0.4 85℃ 0.2 0.0 1.4 1.5 1.6 1.7 Input Voltage : VIN (V) VDFL 1.7 VDR 1.6 1.5 1.4 1.3 -50 1.8 -25 0 25 50 75 Ambient Temperature : (℃) VDF(T)=2.7V 100 VDF(T)=2.7V VIN=2.4V～ 3.0 Detect Voltage, Release Voltage : VDFL, VDR (V) Output Voltage : VOUT(V) 3.2 2.8 2.4 2.0 1.6 1.2 -40℃ 0.8 25℃ 0.4 85℃ 0.0 2.4 2.6 2.8 3 Input Voltage : VIN (V) VDFL 2.9 VDR 2.8 2.7 2.6 2.5 -50 3.2 -25 0 25 50 75 Ambient Temperature : (℃) VDF(T)=5.5V 100 VDF(T)=5.5V VIN=4.8V～ 6.0 Detect Voltage, Release Voltage : VDFL, VDR (V) Output Voltage : VOUT(V) 6.0 5.0 4.0 3.0 -40℃ 2.0 25℃ 1.0 85℃ 0.0 4.8 10/16 5 5.2 5.4 5.6 Input Voltage : VIN (V) 5.8 6 5.9 VDFL 5.8 VDR 5.7 5.6 5.5 5.4 -50 -25 0 25 50 75 Ambient Temperature : (℃) 100 XC6126 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (5) Output Voltage vs. Input Voltage2(VIN≦1.4V) CMOS Output N-ch Open Drain Output 7 1.6 6 Output Voltage : VOUT(V) Output Voltage : VOUT(V) Vpull-Up=6.5V, Rpull=100kΩ 1.8 1.4 1.2 1 0.8 -４0℃ 0.6 25℃ 0.4 85℃ 0.2 0 5 4 3 -４0℃ 2 25℃ 85℃ 1 0 0 0.2 0.4 0.6 0.8 1 Input Voltage : VIN (V) 1.2 1.4 (6) Output Current (Nch Driver) vs. Input Voltage 0 0.2 0.4 0.6 0.8 1 Input Voltage : VIN (V) VDF(T)=1.5V 7 20 16 VOUT=0.5V Output Current : IOUT(mA) -40℃ Output Current : IOUT(mA) 1.4 (7) Output Current (Pch Driver) vs. Input Voltage VDF(T)=5.5V 25℃ 85℃ 12 8 4 0 0 1 2 3 4 Input Voltage : VIN (V) 5 VOUT=VIN-0.5V 25℃ 5 85℃ 4 3 2 1 0 1 2 3 4 Input Voltage : VIN (V) 5 6 (9) Release Delay Time vs. Ambient Temperature 50 Release Delay Time : tDR (μｓ) 100 VDF（T）=1.5V 80 VDF（T）=5.5V 60 40 20 0 -50 -40℃ 6 0 6 (8) Detect Delay Time vs. Ambient Temperature Detect Delay Time : tDF (μｓ) 1.2 -25 0 25 50 75 Ambient Temperature : (℃) 100 VDF（T）=1.5V 40 VDF（T）=5.5V 30 20 10 0 -50 -25 0 25 50 75 Ambient Temperature : (℃) 100 11/16 XC6126 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (10) Leakage Current vs. Ambient temperature N-ch Open Drain Output Leakage Current : ILeak (μA) 0.05 VIN=VOUT=6.0V 0.04 0.03 0.02 0.01 0 25 12/16 35 45 55 65 75 Ambient Temperature : (℃) 85 XC6126 Series ■PACKAGING INFORMATION ●USPN-4B02 (unit：mm) 0.75±0.05 1pin INDENT 0.18±0.05 1 2 4 3 (0.4) ●USPN-4B02 Pattern Layout (unit : mm) ●USPN-4B02Reference 参考パターンレイアウト (unit：mm) 0.23 0.14 ●USPN-4B02 Metal Mask Design (unit : mm) ●USPN-4B02 Reference 参考メタルマスクデザイン (unit：mm) 0.23 0.4 0.18 0.14 0.115 0.18 0.4 0.115 13/16 XC6126 Series ■MARKING RULE SSOT-24 (With the orientation bar at the top) 3 ② ④ ① ③ 4 1 2 ① represents product series, detect voltage range and output configuration.
