SpletWhen the output is shorted to ground or the load current is higher than a certain value, the TPS61088 is disconnected from the load. Similar solutions can be used on the ... In this application, the switching aspects of a MOSFET matter little because the MOSFET is on almost 100% of the time. So, the on resistance, RDS(on), is the key factor. We ... Splet0.23 V. The MOSFET is switched off when the following equation is reached: By extracting IS: Using the current sense ratio of the MOSFET G ID: The current limitation is obtained with the FB pin shorted to ground (VFB = 0 V). This leads to a negative current sourced by this pin, and expressed by: By reporting this expression in the previous one, it

SpletIf a transistor is totally shorted, it's like a piece of wire with very low resistance, which means that even if current is flowing through it, very little power (watts) is dissipated, which means it doesn't make heat. It's possible for a transistor to be partially shorted, so it's a resistor, in which case it would get hot. briswatch mark c hennig

Click to … Splet11. apr. 2024 · Shorted drain-source: A shorted drain-source will result in a low resistance path between the drain and source, causing it to conduct current even when it should be off. You can identify this by measuring the resistance between the drain and source with a multimeter, which should register as very high when the MOSFET is off.
