Dear Dawei, I'm assuming you're using one of the application boards (STEVAL) available on st.com. Could you let me know which board code are you using? If you're using your own design, could you share the schematic, please?I agree that the waveform s...
Hallo @Okeskin , apologizes for the late feedback. We spent some time in the characterization of the characteristic Iout vs. Vout between OUT and GND pins of VN751S. As you can see from the first sheet of the attached excel file, this is not linear....
Hallo @Okeskin . Have you ever considered IPS160H (or IPS160HF) for your design? These part numbers integrate the wire break detection feature: you just need to set an external resistor, while the voltage comparator is integrated. Also, the pin-to-p...
@Okeskin We did a quick check on our side and measured around 40kΩ. We're waiting for the feedback from designers about the internal structure between OUT and GND. I'll keep you posted and according to the feedback we'll consider the possibility of ...
@Okeskin I don't see your computation about the open load detection: independently by VN751S the R30 should be much higher if you expect Vfb.io17 = 19V at Vcc.bat = 24V. . However, I can see ~350uA flowing into VN751S when Vcc.bat =24V and R22 = 27k...
