MOSFET overcurrent protection circuit to avoid power supply burnout accidents

Power supply as electronic equipment distribution components, in addition to the characteristics to consider the provisions of the power supply system equipment, its own protective measures are also very important, such as over-current, over-voltage, over-temperature maintenance. Once the power supply does not have overcurrent protection design program, in the output of short-circuit failure or overload will cause damage to the power supply, but also very likely to further cause the destruction of electronic equipment, and even cause the actual operation of the staff of the electrocution accident and fire and other safety accidents, and overcurrent protection of the power supply with the use of MOSFETs related.
