Resistor short-circuit protective device and protective method used for switching power supply

Номер: CN0101969188A
Принадлежит:

The invention discloses a resistor short-circuit protective device used for a switching power supply. The device is connected into a switching power supply circuit through a power switch and a current detecting resistor, and comprises a comparer, a first phase inverter, a latch counter, a basic counter, a counting locking/starting logic control circuit and a second phase inverter. A resistor short-circuit protective method comprises the following steps of: first, initializing the digital logic of the protective device by utilizing a power-on reset signal to make the latch counter and the basic counter in a reset state; then, making the output of the resistor short-circuit protective device be a high level; switching on the power switch; next, judging whether the voltage of the current detecting resistor is over a threshold voltage in M continuous clock cycles, if so, the resistor is not short-circuited, and otherwise, the resistor is short-circuited; later on, making the output be a low ...
