Title:
CHARGING SYSTEM, ELECTRONIC CIRCUIT DEVICE HAVING SECONDARY CELL AND POWER SUPPLY DEVICE FOR CHARGING
Document Type and Number:
WIPO Patent Application WO/2008/029665
Kind Code:
A1
Abstract:
Provided is a charging system wherein a voltage and a current can be accurately
supplied from a power supply device even with a cable wiring resistance and a connector
contact resistance, and the power supply device can be commonly used even for
a plurality of kinds of electronic circuit devices whereupon different secondary
cells are mounted. The charging system is provided with an electronic circuit
device (50) having a secondary cell (E2), and a power supply device (10) which
can be connected/removed to and from the electronic circuit device and supplies
power for charging the secondary cell when connected. In the charging system,
a detection signal for charge control is transmitted from the electronic circuit
device (50) to the power supply device (10), and the control circuit (12) controls
output from an SW power supply circuit (11) based on the detection signal.
