OPERATIONAL EXPLANATION
(Especially explained for the CMOS output products)
When input voltage (VIN) is higher than detect voltage (VDF), output voltage (VOUT) will be equal to VIN.
(A condition of high impedance exists with N-ch open drain output configurations.)
When input voltage (V
SS) level.
(V
IN) falls below detect voltage (VDF), output voltage (VOUT) will be equal to the ground voltage
When input voltage (VIN) falls to a level below that of the minimum operating voltage (VMIN), output will become
unstable.(As for the N-ch open drain product of XC61CN, the pull-up voltage goes out at the output voltage.)
When input voltage (V
minimum operating voltage (V
IN) rises above the ground voltage (VSS) level, output will be unstable at levels below the
MIN). Between the VMIN and detect release voltage (VDR) levels, the ground voltage (VSS)
level will be maintained.
When input voltage (V
IN) rises above detect release voltage (VDR), output voltage (VOUT) will be equal to VIN.
(A condition of high impedance exists with N-ch open drain output configurations.)
The difference between V
DR and VDF represents the hysteresis range.

NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded.
2. When a resistor is connected between the VIN pin and the power supply with CMOS output configurations, oscillation may
occur as a result of voltage drops at R
3. When a resistor is connected between the V
N-ch open-drain output configurations, oscillation may occur as a result of through current at the time of voltage release even if load current (I
4. Please use N-ch open drain output configuration, when a resistor R
source. In such cases, please ensure that RIN is less than 10k and that C is more than 0.1μF, please test with the actual device. (refer to the Oscillation Description (1) below)
5. With a resistor RIN connected between the V
power supply voltage as a result of the IC's supply current flowing through the V
6. In order to stabilize the IC's operations, please ensure that V

7. 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.
Oscillation Description
(1) Load current oscillation with the CMOS output configuration
When the voltage applied at power supply, release operations commence and the detector's output voltage increases. Load current (IOUT) will flow at RL. Because a voltage drop (RIN x IOUT) is produced at the RIN resistor, located between the power supply and the V voltage level at the V commence. Following detect operations, load current flow will cease and since voltage drop at R voltage level at the V Oscillation may occur with this " release - detect - release " repetition. Further, this condition will also appear via means of a similar mechanism during detect operations.
(2) Oscillation as a result of through current
Since the XE61C series are CMOS IC release and detect operations). Consequently, oscillation is liable to occur as a result of drops in voltage at the through current's resistor (R Since hysteresis exists during detect operations, oscillation is unlikely to occur.
Power supply

IN pin. When the VIN pin voltage level falls below the detect voltage level, detect operations will
