Note: For explaining in a simplified case, an operation time of the circuit is not counted.

The following explains the operation of the typical application circuit along number symbols shown in the timing chart.

①

When input voltage (V_IN) rises above detect voltage (V_DF), output voltage (V_OUT) will be equal to input voltage (V_IN). (A

condition of high impedance exists with N-ch open drain output configurations.)

②

③

When input voltage (V_IN) falls below detect voltage (V_DF), output voltage (V_OUT) will be equal to the ground voltage

(V_SS) level.

When input voltage (V_IN) falls to a level below that of the minimum operating voltage (V_MIN), output will become

unstable. If In this condition, V_INwill equal the pulled-up output (should output be pulled-up.) (Input voltage, V_IN, in

the typical application circuit.)

④

⑤

When input voltage (V_IN) rises above the minimum operating voltage (V_MIN) level until it achieves a release voltage

(V_DR), output keeps the ground voltage level (V_SS).

When the input voltage (V_IN) rises above the release voltage (V_DR), output voltage (V_OUTwill be equal to input voltage

(V_IN). (A condition of high impedance exists with N-ch open drain output configurations.)

The difference between V_DRand V_DFrepresents the hysteresis width.

■NOTE ON USE

1. Please use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent

damage to the device.

2. In order to stabilize the IC's operations, please ensure that V_INpin's input frequency's rise and fall times are more than

several μs / V.

3. With a resistor connected between the V_INpin and the power supply V_DDsome errors may be observed from the input

voltage at the detect and release voltage. Those errors are not constant because of the fluctuation of the supply current.

4. When a resistor is connected between the V_INpin and the power supply V_DD, oscillation may occur as a result of through

current and voltage drop at the R_INat the time of voltage release. (refer to the Oscillation Description (1) below ) Especially

in the CMOS output configurations, oscillation may occur regardless of detect/release operation if load current (I_OUT

exists. (refer to the Oscillation Description (2) below)

)

5. Please use N-ch open drains configuration, when a resistor R_INis connected between the V_INpin and the power supply

V_DDpower source. In such cases, please ensure that R_INis less than 10kΩ and that C is more than 0.1μF.

●

Oscillation Description

(1) Oscillation as a result of through current

Since the XC6120 series are CMOS ICs, transient through current will flow when the IC's internal circuit switching operates

regardless of output configuration. Consequently, oscillation is liable to occur as a result of the similar operations as in (1)

above. This oscillation does not occur during the detect operation.

(2) Output current oscillation with the CMOS output configuration

As shown in figure 2, when the voltage applied at the power supply (V_DD) rises from below detect voltage to above release

voltage, the IC commence release operations and the internal P-ch driver transistor will be on. The output current (I_OUT) flows

the input resistor (R_IN) via the P-ch driver transistor. Because of the input resistor (R_IN) and the output current (I_OUT), an input pin

voltage drops R_INx I_OUT

. If the voltage drop level is larger than the IC’s hysteresis width (V_HYS), the input pin voltage will falls

below the V_DFand detect operations will commerce so that the internal P-ch driver transistor will be off. The voltage drop will

stop because the output current (I_OUT) which was flowing the P-ch driver transistor will run down. The input pin voltage will

become the same voltage level as the input voltage (V_IN). For this, the input pin voltage will rise above the release voltage (V_DR),

therefore, the release operations will begin over again. Oscillation may occur with this repetition. Further, this condition will

also appear via means of a similar mechanism during detect operations.
