LC709202F
CMOS LSI
1-Cell Li+ (lithium-ion)
Battery Monitor IC
http://onsemi.com
Overview
The LC709202F is an IC that measures the remaining power level of 1-cell lithium-ion (Li+) batteries used for a
portable equipment etc.
This product is able to reduce a fuel gauge errors by implementing its unique correction technology for measurement
value of battery temperature and voltage.
It is possible for this to realize high precision for measurement in battery power measurement IC that does not need a
current sensing resistor. (±3% under certain conditions)
Applications
• Wireless Handsets
• Smartphones/PDA devices
• MP3 players
• digital cameras
• Portable Game Players
• USB-related devices
