XC6132 Series ETR02032-002 Delay capacitor adjustable voltage detectors with sense pin isolation, surge voltage protection and HYS external adjustment ■GENERAL DESCRIPTION The XC6132 series are ultra-small delay capacitor adjustable type voltage detectors that have high accuracy and sense pin isolation. High accuracy and a low supply current are achieved by means of a CMOS process, a highly accurate reference power supply, and laser trimming technology. The sense pin is isolated from the power input pin to enable monitoring of the voltage of another power supply. Output can be maintained in the detection state even if the voltage of the power supply that is monitored drops to 0V. The sense pin is also suitable for detecting high voltages, and the detection and release voltage can be set as desired using external resistors. An internal surge voltage protection circuit and an internal delay circuit are also provided. By connecting a capacitor to the Cd/MRB pin, any release delay time and detect delay time can be set and the pin can also be used as a manual reset pin. The HYS external adjustment pin can be used to establish a sufficient hysteresis width. ■FEATURES ■APPLICATIONS ●Microcontroller reset and malfunction monitoring ●Battery voltage monitoring ●System power-on reset ●Power failure detection Operating Ambient Temperature Operating voltage range Detect voltage range Detect voltage accuracy (Ta=25℃) Detect voltage accuracy (Ta=-40~125℃) Temperature Characteristics Hysteresis width Adjustable Pin for Hysteresis Width Low supply current Manual reset function Output type Output logic Delay capacitance pin Sense pin Packages Environment friendly : -40℃~+125℃ : 1.6V~6.0V : 0.8V~2.0V : ±18mV(VDF<1.5V) : ±1.2%(1.5V≦VDF≦2.0V) : ±36mV(VDF<1.5V) : ±2.7%(1.5V≦VDF≦2.0V) : ±50ppm/℃(TYP.) : VDF×0.1%(TYP.) : Yes : 1.28μA(TYP.)

Fig. 1: Typical block diagram (Active Low product) VSEN pin voltage:VSEN(MIN.:0V,MAX.:6.0V) Release voltage:VDF+VHYS Detect voltage:VDF Cd/MRB pin voltage:VCd/MRB(MIN.:VSS,MAX.:VIN) Cd pin threshold voltage:VTCd1,VTCd2 Output voltage:VRESETB(MIN.:VSS,MAX.:VIN) tDF ① ② tDR ③ ④⑤ ⑥ Fig. 2: Timing chart of Fig. 1(VIN=6.0V、Active Low product) ①In the initial state, a voltage that is sufficiently high (MAX.:6.0V) with respect to the release voltage is applied to the VSEN pin, and the delay capacitance Cd is charged up to the power input pin voltage. The VSEN pin voltage starts to fall, and during the time until it reaches the detect voltage (VSEN>VDF), VRESETB is High level (=VIN). Note: If the pull-up resistor is connected to a power supply other than the power input pin VIN when using the Nch open drain output (XC6132N), High level will be the voltage of the power supply to which the pull-up resistor is connected. 15/30 XC6132 Series ■OPERATIONAL DESCRIPTION (Continued) ②The VSEN pin voltage continues to drop, and when it reaches the detect voltage (VSEN=VDF), the Nch transistor for delay capacitance discharge turns ON, and discharge of the delay capacitance Cd starts through the delay resistor Rn. The time from VSEN=VDF until VRESETB reaches Low level is the detect delay time tDF (the detect time when the capacitor is not connected to the Cd/MRB pin is tDF0). The delay capacitance Cd is discharged through the delay resistor Rn when it is above the threshold voltage of VTCD2. When it is below the threshold voltage of VTCD2, the delay capacitance Cd is discharged faster through the internal built-in low impedance switch. ③During the time that the VSEN pin voltage is below the detect voltage VDF, the delay capacitance Cd discharges to ground level. The VSEN pin starts rising again, and during the time until it reaches the release voltage (VSENVDF), VRESETB holds High level. The above operation description is for an Active Low detection product. For an Active High product, reverse the logic of the reset pin. In the factory shipping state, internal hysteresis is not added (VHYS =VDFx0.001V(TYP.)), so please add a hysteresis of 1% or more with an external resistor. For the calculation method, refer to below. Also please refer to “Notes on use 5&6” on page 19. Hysteresis can be added as desired by inserting a resistor between the node to monitor and VSEN pin, and between the VSEN pin and HYS pin. The calculation method for adding hysteresis by increasing only the release voltage and leaving the detect voltage unchanged is given below. For the circuit schematic, refer to Fig. 3: Hysteresis Augmentation Circuit 1. VDR(H)=VDR(T)×{1+(RD/RE)} Hysteresis width=VDR(H)-VDF(T) Example 1: RD=200kΩ, RE=200kΩ, VDF(T)=1.000V, VDR(T)=1.001V. VDR(H)=2.002V Hysteresis width=2.002-1.000 =1.002V The calculation method for detecting high voltage and adding hysteresis is shown below. For the circuit schematic, refer to Fig. 4: Hysteresis Augmentation Circuit 2. VDF(H)=VDF(T)×{1+(R1/R2)} VDR(H)=VDR(T)×{1+(R1/R2)+(R1/R3)} Hysteresis width=VDR(H)-VDF(H) Example 2: R1=R3=500kΩ, R2=200kΩ, VDF(T)=2.000V, VDR(T)=2.002V. VDF(H)=7.0V VDR(H)=9.009V Hysteresis width=9.009-7.0=2.009V (Note 1) VDF(H) is the detect voltage after external adjustment. (Note 2) VDR(H) is the release voltage after external adjustment. (Note 3) VDR(T) is the release voltage. (Note 4) VDF(T) is the detect voltage. (Note 5) The R2 resistance is in parallel with the internal RSEN resistance, and thus to increase the accuracy of the detect voltage and release voltage after external adjustment, select an R2 resistance that is sufficiently small with respect to the RSEN resistance. For RSEN resistance values, refer to SPEC TABLE (p.11). (Note 6) If high voltage is to be detected, divide the voltage with resistors R1 and R2 so that VSEN pin≦6V. The battery voltage (+B) assumes up to 12V in this case.

The ratio of the delay resistances (Rp and Rn) is selectable from 5 options. The delay time is adjustable using the combination of delay resistance and delay capacitance value. (Refer to “Selection Guide”) The release delay time (tDR) is calculated using Equation (1). * ln is the natural logarithm. tDR=Rp×Cd×{-ln(1-VTCd1/VIN)}+tDR0 …(1) The delay capacitance pin threshold voltage is VTCd1=VIN/2(TYP.), and thus when tDR0 can be neglected, the release delay time can be calculated simply using Equation (2). tDR=Rp×Cd×[-ln{1-(VIN/2)/VIN}]=Rp×Cd×0.693 …(2) The detect delay time (tDF) is calculated using Equation (3). tDF=Rn×Cd×{-ln(VTCd2/VIN)}+tDF0 …(3) * ln is the natural logarithm. The delay capacitance pin threshold voltage is VTCd2=VIN/2 (TYP.), and thus when tDF0 can be neglected, the detect delay can be calculated simply using Equation (4). tDF=Rn×Cd×{-ln(VIN/2)/VIN}=Rn×Cd×0.693 …(4) Example 3: When type A is selected (Rp:Rn=144kΩ:0Ω),the delay times are as follows: If Cd is set to 0.1uF, tDR=144×103×0.1×10-6×0.693=10ms tDF is the detect delay time (tDFO) when the delay capacitance Cd is not connected. Example 4: When type B is selected (Rp:Rn=144kΩ:18kΩ),the delay times are as follows: If Cd is set to 0.1uF, tDR=144×103×0.1×10-6×0.693=10ms tDF =18×103×0.1×10-6×0.693=1.25ms (Note 7) The release delay times tDR in Examples 3 and 4 are the values calculated from Equation (2). (Note 8) The detect delay time tDF in Example 4 is the value calculated from Equation (4). (Note 9) Note that the delay times will vary depending on the actual capacitance value of the delay capacitance Cd. The Cd/MRB pin can also be used as a manual reset pin. When the Cd and RESET switch are connected to the Cd/MRB pin (refer to Fig.1), and under the release condition, if the RESET switch turns on, then the detect signal is generated at the RESET/RESETB pin forcibly. For Active Low type (RESETB), under the release condition, if the RESET switch turns on, then the voltage at the RESETB pin changes from H to L after the detect delay time. For Active High type (RESET), under the release condition, if the RESET switch turns on, then the voltage at the RESET pin changes from L to H after the detect delay time. Under the detect condition, the condition will be kept even if the RESET switch turns on and off. In the case that either H level or L level is fed to the Cd/MRB pin without the RESET switch, the behavior of the XC6132 follows the timing chart in Fig. 5. L level is fed to the MRB pin under the detect condition, the RESET switch will be kept. H level is fed to the MRB pin under the detect condition, the RESET switch will be undefined. Even though the voltage at the VSEN pin changes from a higher voltage than the detect voltage to a lower voltage, as long as H level is fed to the MRB pin, the release condition is kept. If H level or L level is fed to the Cd/MRB pin forcibly, then even though Cd is connected to the pin, the XC6132 can’t have any delay time.

A surge current of +2.5mA(≧200ms), -2.5mA(≧20ms) is possible. A positive surge current (ISENSURGE(+)) flows when M1 is turned ON by a SURGE VOLTAGE PROTECT BLOCK signal. A negative surge current (ISENSURGE(-)) is made to flow by the M1 parasitic diode. When a positive surge current flows and the surge voltage protection circuit activates, the VSEN pin voltage rises in proportion to the VIN voltage and surge current, so adjust the ISEN current with an external resistor so that the VSEN pin voltage does not exceed the operating voltage. Refer to Fig. 7. ※The VSEN voltage rise is most pronounced at high temperature. Example 5: When VIN=3.3V and ISENSURGE(+)=2.5mA (MAX), the VSEN pin voltage from Fig. 7 is 5.6V. If the maximum battery voltage (+B) pin voltage is 100V, a voltage of (100-5.6)=94.4V will be applied to the R1 resistor. To keep the surge current from exceeding 2.5mA, use a resistance of R1=V/I=94.4/0.0025=37.8kΩ or above. Example 6: When VIN = 3.3V and ISENSURGE(-) = -2.5mA(MAX), Vf of the parasitic diode M1 is -0.9V (MAX). If the battery voltage (+B) maximum is -100V, the voltage applied to the R1 resistor will be {-100 - (-0.9)} = -99.1V. To limit the surge current to -2.5mA, set the R1 resistance to R1 = V/I= -99.1/-0.0025 = 39.6kΩ or higher. If the surge voltage on the positive side is different from the negative side, calculate the R1 resistance value using the side where the voltage difference applied to the R1 resistor is greatest. +B Resistance for hysteresis external adjustment R1 R2 HYS R3 VSEN RSEN=RA+RB+RC RA + SURGE VOLTAGE PROTECT BLOCK RB M1 - VIN ↓ISENSURGE (+) VREF ↑ISENSURGE(-) RC M2 Surge voltage protect circuit Fig. 6: Surge voltage protect circuit Fig. 7: Example of VIN-VSEN characteristics 18/30 M3 XC6132 Series ■NOTES 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) The power input pin voltage may fall due to the flow through current during IC operation and the resistance component between the power supply and the power input pin. In the case of CMOS output, a drop in the power input pin voltage may occur in the same way due to the output current. When this happens, if the power input pin voltage drops below the minimum operating voltage, a malfunction may occur. 3) Note that large, sharp changes of the power input pin voltage may lead to malfunction. 4) Power supply noise is sometimes a cause of malfunction. Sufficiently test using the actual device, such as inserting a capacitor between VIN and GND. 5) Internal hysteresis is not initially included with the product. Connect external resistors to the VSEN pin and HYS pin to add a hysteresis of 1% or more. Note that if hysteresis is not added with external resistors, oscillation will occur when switching takes place at the detect voltage or the release voltage. 6) There is a possibility that oscillation will occur if the resistances of the VSEN pin and HYS pin are high. Use a resistance of 1MΩ or less between the node to monitor and VSEN pin, and between the VSEN pin and HYS pin. 7) Exercise caution if VIN and VSEN are started in common, as the output will be undefined until VIN reaches the operating voltage. 8) For a manual reset function, in case when the function is activated by feeding either MRB H level or MRB L level to Cd/MRB pin instead of using a reset switch, please note these phenomena below; ・The RESET output signal will be undefined when MRB H is fed to Cd/MRB pin under the detect condition. ・The RESET output signal will be undefined based on the voltage relationship between VSEN pin and Cd/MRB pin. 9) When an N-ch open drain output is used, the VRESETB voltage at detection and release is determined by the pull-up resistance connected to the output pin. Refer to the following when selecting the resistance value. At detection: VRESETB=Vpull/(1+Rpull/RON) Vpull:Voltage after pull-up RON(*1):ON resistance of N-ch driver M6 (calculated from VRESETB/IRBOUTN based on electrical characteristics) Example: When VIN=2.0V(*2), RON=0.3/4.2×10-3=71.4Ω (MAX.). If it is desired to make VRESETB at detection 0.1V or less when Vpull is 3.0V, Rpull={(Vpull/VRESETB)-1}×RON={(3/0.1)-1}×71.4≒2.1kΩ Therefore, to make the output voltage at detection 0.1V or less under the above conditions, the pull-up resistance must be 2.1kΩ or higher. (*1) Note that R ON becomes larger as VIN becomes smaller. (*2) For V in the calculation, use the lowest value of the input voltage range you will use. IN At release: VRESETB=Vpull/(1+Rpull/Roff) Vpull: Voltage after pull-up Roff: Resistance when N-ch driver M6 is OFF (calculated from VRESETB/ILEAKN based on electrical characteristics) Example: When Vpull is 6.0V, Roff=6/(0.1×10-6)=60MΩ (MIN.). If it is desired to make VRESETB 5.99V or higher, Rpull={(Vpull/VRESETB)-1}×Roff={(6/5.99)-1}×60×106≒100kΩ Therefore, to make the output voltage at release 5.99V or higher under the above conditions, the pull-up resistance must be 100kΩ or less. 10) If the discharge time of the delay capacitance Cd at detection is short and the delay capacitance Cd cannot be discharged to ground level, charging will take place at the next release operation with electric charge remaining in the delay capacitance Cd, and this may cause the release delay time to become noticeably short. 11) If the charging time of the delay capacitance Cd at release is short and the delay capacitance Cd cannot be charged to the VIN level, the delay capacitance Cd will discharge from less than the VIN level at the next detection operation, and this may cause the detect delay time to become noticeably short. 12) Torex places an importance on improving our products and their reliability.
