| description | A discharge protection circuit for discharging a full-bridge circuit in a brushless DC fan, wherein the brushless DC fan comprises a control circuit outputting at least one first control signal and at least one second control signal to the full-bridge circuit. The second control signal is a reverse signal of the first control signal; and the full-bridge circuit comprises a first impedance, a second impedance and a switch. The switch has a first terminal, a second terminal, and a third terminal that is grounded. The first terminal and the first impedance are in series connection for receiving the first control signal to control the status of the switch. The second terminal and the second impedance are in series connection and are connected to the input terminal of the second control signal of the full-bridge circuit, and the full-bridge circuit is discharged according to the status of the switch. |
