Protection circuit
A protection circuit, comprising: a transient suppression circuit, configured to suppress a transient voltage; and a short-circuit protection circuit connected between the transient suppression circuit and a ground terminal, wherein when the transient suppression circuit is shorted out and the transient voltage is a protection voltage, the short-circuit protection circuit disconnects a loop where the transient suppression circuit is located. The short-circuit protection circuit has a turned-on state and a turned-off state; the short-circuit protection circuit is in a turned-on state when the transient suppression circuit is shorted out and the transient voltage is greater than the protection voltage; and the short-circuit protection circuit is in a turned-off state when the transient suppression circuit is shorted out and the transient voltage is a protection voltage.
