    摘要: 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.

    摘要: For a charge pump, a control circuit switches two or more input voltages to apply to one or more pumping capacitors under auto-sensing control to modulate a maximum pumping voltage as close as to a demanded output voltage to thereby reduce the difference between the maximum pumping voltage and the output voltage for efficiency and thermal improvement of the charge pump. The maximum pumping voltage is produced by mixing the different input voltages and the charge pump may provide more operation modes.
