1 / 23 page © Semiconductor Components Industries, LLC, 2015 1 Publication Order Number: March 2015- Rev. 8 LC709203F/D LC709203F Smart LiB Gauge Battery Fuel Gauge LSI for 1-Cell Lithium-ion (Li+) Overview LC709203F is a Fuel Gauge for a single lithium ion battery. It is part of our Smart LiB Gauge family of Fuel Gauges which measure the battery RSOC (Relative State Of Charge) using its unique algorithm called HG-CVR. The HG-CVR algorithm eliminates the use of a sense resistor and provides accurate RSOC information even under unstable conditions (e.g. changes of battery; temperature, loading, aging and self- discharge). An accurate RSOC contributes to the operating time of portable devices. LC709203F is available in two small packages realizing the industries smallest PCB footprint for the complete solution. It has minimal parameters to be set by the user enabling simple, quick setup and operation. Features HG-CVR algorithm technology No external sense resistor 2.8% accuracy of RSOC Accurate RSOC of aging battery Automatic convergence of error Adjustment for the parasitic impedance around the battery Simple and Quick Setup Low power consumption 3μA Operational mode Precision Voltage measurement ±7.5mV Precision Timer ±3.5% Alerts for Low RSOC and / or Low Voltage Temperature compensation Sense Thermistor input Via I2C Detect Battery insertion I2C Interface (up to 400 kHz supported) Applications Wireless Handsets Smartphones / PDA devices MP3 players Digital cameras Portable Game Players USB-related devices www.onsemi.com ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 23 of this data sheet WDFN8 3x4, 0.65P Pb-Free, Halogen Free type WLCSP9, 1.60x1.76 Pb-Free, Halogen Free type * I 2C Bus is a trademark of Philips Corporation. |
