BASIC OPERATION
Operation of the IXD5120 in a typical application circuit is exlained by the timing diagram shown below.
Note: To simplfy explanation, an operation time of the circuit is not included.

Product Specification
IXD5120
When input voltage VIN is higher than detect voltage VDF, output voltage VOUT is equal input voltage VIN. (Output
of the IXD5120N version with N-channel open drain is in high impedance state.)
When input voltage VIN falls below detect voltage VDF, output voltage VOUT becomes equal to the ground voltage
VSS level.
When input voltage VIN falls below minimum operating voltage VMIN, output becomes unstable. In this condition,
VOUT is equal pull-up voltage, which is VIN in typical application.
When input voltage VIN rises above the minimum operating voltage VMIN, output keeps the ground voltage level
VSS, until VIN becomes equal or higher than a release voltage VDR.
When the input voltage VIN rises above the release voltage VDR, output voltage VOUT becomes equal to the input
voltage VIN. (Output of the IXD5120N version with N-channel open drain is in high impedance state.)
The difference between VDR and VDF represents the hysteresis width.
TYPICAL APPLICATION CIRCUIT
IXD5120C
IXD5120N
LAYOUT AND USE CONSIDERATIONS
1. The IC may malfunction if absolute maximum ratings are exceeded.
2. To stabilize the IC's operations, please, ensure that VIN rise and fall times are more than several μs/V.
3. IXD5120N version with N-channel open drain configuration is recommended, when a resistive divider is
used to set VIN voltage (see figure below). Voltage drop at resistor RIN caused by supply and load currents,
changes level of detect and release voltages. Those errors are not constant because of the fluctuation of
currents. In addition, oscillation may occur if voltage drop caused by load or transient current exceeds
hysteresis VHYS = VDR - VDF. In such cases, please ensure that RIN is less than 10 kΩ and that C is more
than 0.1 μF.
