Patent ID: 8912783

Claim:
A power-supply controller circuit comprising: a power-supply switch unit configured to output an ON-signal when operated manually; a switching unit configured to switch ON and OFF an output voltage to a controller unit in response to the ON-signal of the power-supply switch unit; a latching unit configured to latch the ON-state of the switching unit, when the power-supply switch unit outputs an ON-signal under a condition where the switching unit is in the OFF-state; and a controller unit configured to control an unlatching signal to unlatch the ON-state latched by the latching unit when the latching unit is in the ON-state and detects the ON-signal sent from the power-supply switch unit, wherein the latching unit includes: a first latch configured to continue to latch the ON-state, while the ON-state is being latched, irrespective of whether or not there is an ON-signal sent from the power-supply switch unit; and a second latch configured to unlatch the ON-state latched by the first latch.
