XCM410 Series
2 Channel Voltage Detector (Sense Pin separated from VDD)
ETR2426_001
GENERAL DESCRIPTION
The XCM410 series is a multi combination module IC which comprises of two voltage detectors, XC6108 and XC6109 series. The two detectors inside are highly precise, low power consumption voltage detectors using laser trimming technology. The sense pin (VSEN) for channel 1 (VOUT1) is separated from power supply (VIN) so that it allows this pin to monitor added power supply. This feature enables output to maintain the state of detection even when voltage of the monitored power supply drops to 0V. The output configuration is N-channel open-drain.
APPLICATIONS
Microprocessor reset circuitry Charge voltage monitors Memory battery back-up switch circuits Power failure detection circuits

Figure1 is typical application circuit, and Fifure2 is timing chart of figure1.
Figure 1: Typical application circuit example
Input Voltage: VIN Release Voltage: VDF2+VHYS2 Detect Voltage: VDF2 Minimum Operation Voltage: 1.0V Sense Pin Voltage: VSEN Release Voltage: VDF1+VHYS1 Detect Voltage: VDF1
Output Voltage: VOUT1
Output Voltage: VOUT2
Figure 2: The timing chart of Figure 1
As an early state, the VIN power supply pin and the VSEN sense pin are applied sufficiently high voltage (6.0V MAX.). While the sense pin voltage VSEN starts dropping to the detect voltage VDF1 (VSEN>VDF1), the output voltage VOUT1 keeps high level (=VIN). * If a pull-up resistor of the N-ch open drain is connected to added power supply different from the input voltage pin, the high level will be a voltage value where the pull-up resistor is connected.
When the sense pin voltage keeps dropping and becomes equal to the detect voltage (VSEN =VDF1), the output voltage changes into the low level (VINx0.1). The detect delay time tDF1 is defined as time which ranges from VSEN=VDF1 to the VOUT1 goes in low level.
The output voltage (VOUT1) maintains low level while the sense pin voltage increases again to reach the release voltage (VSEN< VDF1 +VHYS1). The release delay time tDR1 is defined as time which ranges from sense pin voltage reaches release voltage (VSEN VDF1+VHYS1) to the VOUT1 goes in high level.

OPERATIONAL EXPLANATION (Continued)
The output voltage VOUT1 maintains high level (=VIN) while the sense pin voltage more than detect voltage (VSEN>VDF1). The VIN input voltage pin is applied sufficiently high voltage to the release voltage (VDF2+VHYS2). While the input pin voltage VIN starts dropping to the detect voltage VDF2 (VIN > VDF2), the output voltage VOUT2 keeps high level (=VIN). * If a pull-up resistor of the N-ch open drain is connected to added power supply different from the input voltage pin, the high level will be a voltage value where the pull-up resistor is connected. When the input pin voltage keeps dropping and becomes equal to the detect voltage (VIN = VDF2), the output voltage changes into low level ( goes in low level. While the input pin voltage keeps below the detect voltage VDF2, and 1.0V or more, the output voltage VOUT2 maintains low level. While the input pin voltage drops to 1.0V or less and it increases again to 1.0V or more, the output voltage (VOUT2) may not be able to maintain low level. Such an operation is called "Undefined Operation", and the output voltage from the VOUT2 pin is called undefined operating voltage VUNS. While the input pin voltage increases from 1.0V to the release voltage level (VIN VDF2 +VHYS2), the output voltage (VOUT2) maintains low level. The release delay time tDR2 is defined as time which ranges from the VIN power supply voltage pin reaches release voltage (VINVDF2+VHYS2) to the VOUT2 goes in high level. The output voltage VOUT2 maintains high level (=VIN) while the power supply voltage more than detect voltage (VIN>VDF2). If a pull-up resistor Rpull1 of the N-ch open drain is connected to power supply VIN, output voltage VOUT1 becomes same to the input voltage VIN. While the VIN power supply voltage drops below 1.0V and increases again to 1.0V or more, the output voltage VOUT2 may not be able to maintain low level. VIN 0.1). The detect delay time tDF2 is defined as time which ranges from VIN =VDF to the VOUT

NOTE ON USE
1. Use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent
damage to the device.
2. The power supply input pin voltage drops by the resistance between power supply and the VIN pin, and by through current
at operation of the IC. At this time, the IC may go into malfunction if the power supply input pin voltage falls below the minimum operating voltage range. 3. When the sense voltage is less than 1.0V, be sure to separate the VIN pin and the sense pin, and to apply the voltage over 1.0V to the VIN pin. 4. Note that a rapid and high fluctuation at the power supply input pin voltage may cause a wrong operation. 5. In N channel open drain output, VOUT voltages at detect and release are determined by resistance of a pull-up resistor connected at the VOUT pin. Please choose proper resistance values with referring to Figure 3; During detection VOUT=Vpull / (1+Rpull / RON) Vpull Pull-up voltage RON(*1) On-resistance of N channel driver M3 can be calculated as VDS / IOUT1 from electrical characteristics, For example, when (*2) RON = 0.5 / 0.8 10-3 = 625 MIN. at VIN=2.0V, Vpull = 3.0V and VOUT 0.1V at detect, Rpull= (Vpull /VOUT-1) RON= (3 / 0.1-1) 625 18 In this case, Rpull should be selected higher or equal to 18k in order to keep the output voltage less than 0.1V during detection. (*1) VIN is smaller RON is bigger, be noted. (*2) For calculation, minimum VIN should be chosen among the input voltage range. During releasing VOUT = Vpull / (1 + Rpull / ROFF) Vpull Pull-up voltage ROFF On-resistance of N channel driver M3 is 15M MIN. when the driver is off (as to VOUT / ILEAK) For example when Vpull = 6.0V and VOUT 5.99V, Rpull = (Vpull / VOUT-1) Roff = (6/5.99-1) 15 106 25 k In this case, Rpull should be selected smaller or equal to 25 k in order to obtain output voltage higher than 5.99V during releasing.
