Assignee: SEIKO EPSON CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. The electronic device according to claim 7, wherein
the discharge system circuit includes:
the regulator configured to supply the regulated power supply voltage based on the battery voltage to the power feeder circuit; and
a power-on reset circuit configured to generate a power-on reset signal based on the regulated power supply voltage,

the power-off setting circuit includes a first latch circuit and a second latch circuit,
the second latch circuit outputs a power-off control signal indicating the power-off state when the power-on reset signal is in a reset state,
the charge system circuit outputs a power-off release signal to the power-off setting circuit after the power receiving unit starts receiving the power,
the first latch circuit outputs a power-off release trigger signal based on the power-off release signal, and
the second latch circuit outputs the power-off control signal indicating release of the power-off state when the power-off release trigger signal is input.
