Hi team,
Regarding LM74722-Q1 -
- If OV pin is not used, how should I connect this pin? Can I connect it to ground via a pull-down resistor and what is the recommended pull-down resistor?
- Regarding Zener usage, if the selected MOSFET has VGS,max = 20V, do I still need to put the Zener to protect VGS <14V? Or I can just remove it?
- Regarding inrush current limit capacitor CdVdT, using equation (1) in datasheet, based on IPD_DRV = 50uA, Cload = 470uF, Iinrush = 250mA in datasheet example, the calculated CdVdT is 94nF (or round up to 100nF) instead of 10nF in datasheet. Is the equation wrong or the example is wrong?
