product specification IXD5120 ps03 43 01 - 0515 preliminary 5 ? when input voltage v in is higher than detect voltage v df , output voltage v out is equal input voltage v in . ( output of the IXD5120n version with n - channel open drain is in high impedance state . ) ? when input voltage v in falls below detect voltage v df , output voltage v out becomes equal to the ground v oltage v ss level. ? when input voltage v in falls below minimum operating voltage v min , output become s unstable. in this condition, v out is equal pull - up voltage, which is v in in typical application. ? when input voltage v in rises above the minimum operating voltage v min , output keeps the ground voltage level v ss , until v in becomes equal or higher than a release voltage v dr . ? when the input voltage v in rises above the release voltage v dr , output voltage v out becomes equal to the input voltage v in . ( output of the IXD5120n version with n - channel open drain is in high impedance state.) ? the difference between v dr and v df 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. t o stabilize the ic's operations, please , ensure that v in rise and fall times are more than several s/v. 3. IXD5120n version with n - channel open drain configuration is recommended, when a resistive divider is used to set v in voltage (see figure below). voltage drop at resistor r in caused by supply and load current s, changes level of detect and release voltages. those errors are not constant because of the fluctuation of current s . in addition, oscillation may occur if voltage drop caused by load or transient current exceeds hysteresis v hys = v d r - v d f . in such cases , please ensure that r in is less than 10 k and that c is more than 0.1 f.
