The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance taken into consideration by increasing board size and copper area so as not to exceed the maximum junction temperature rating.

When the voltage applied to the VDD reaches the applicable threshold voltage, the VOUT level switches from either “H”→“L” or from “L”→“H”. BD52xxNVX-2C series have delay time function, which set tPLH (output “L”→”H”) using an external capacitor connected in CT pin (CCT). Because the BD52xxNVX-2C series uses an open drain output type, it is necessary to connect a pull up resistor to V DD or another power supply. [In this case, the output (VOUT) “H” voltage becomes VDD or the voltage of the other power supply]. VDD VOUT Vref Delay Circuit GND CT Figure 17. (BD52xxNVX-2C type internal block diagram) Setting of Detector Delay Time Delay time L→H (tPLH) is the time when VOUT rises to 1/2 of VDD after VDD rises up and beyond the release voltage (VDET+∆VDET). Delay time L→H (tPLH) is determined by CT capacitor and can be calculated from the following formula. When CT capacitor ≥ 1nF, tCTO has less effect and tPLH computation is shown on Example No.2. The result has ±50 % tolerance within the operating temperature range of -40 °C to +125 °C.
