Common problems in using power MOSFET circuits include:
1.Conduction loss: the energy loss when the MOSFET is conducting.
2.Switching loss: the energy loss generated during the switching process.
3.Thermal runaway: the accumulation of heat may lead to the failure of the device.
4.Gate driving problem: inappropriate driving signals may affect the performance.
5.Short-circuit withstand capacity: the withstand capacity in the case of a short circuit.
6.Current sharing problem of parallel devices: the uneven current distribution when multiple devices are paralleled.
