The present invention discloses a short-circuit detection circuit and a short-circuit detection method. The short-circuit detection circuit detects whether an output node is short-circuited to a first predetermined level. A first switch circuit which is controlled by a control signal is coupled between the output node and a second predetermined level. The short-circuit detection circuit includes: a determination circuit, which is coupled between the output node and the second predetermined level, wherein when the determination circuit is enabled, it generates a determination signal according to whether the output node is short-circuited to the first predetermined level; and a second switch circuit, which generates a short-circuit detection signal according to the determination signal.
