How do I calcuate "SENSE Threshold Overdrive Voltage percent" to determine the "SENSE Pulse duration" in Figure 9 of the datahsheet?  In my application, I have addition hysteresis resistor Rh.


  • Sam,

    Figure 9 is not based on calculation but on data of sampled points on actual device units. Figure 9 shows a typical approximation. Overdrive is calculated as: Overdrive = | (V_sense / V_IT-   -  1) x 100% |

    Please let me know if you have additional questions.
