Abstract:
A power-supply controller circuit includes: a power-supply switch unit configured to output an ON-signal when manually operated; 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 an 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 an OFF-state; and the 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.
