LC709203FQH-04TWG ON Semiconductor

Smart LiB Gauge Battery Fuel Gauge LSI For 1Cell Lithiumion/ Polymer (Li+) LC709203F www.onsemi.com Overview LC709203F is a Fuel Gauge for a single lithium ion/polymer 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 1 eliminates the use of a sense resistor and provides accurate RSOC WDFN8 WLCSP9 CASE 509AF CASE 567JH 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. MARKING DIAGRAMS LC709203F is available in two small packages realizing the WDFN8 industries smallest PCB footprint for the complete solution. It has minimal parameters to be set by the user enabling simple, quick setup 9203F and operation. ** ASWLYW Features HGCVR Algorithm Technology 9203F**= Specific Device Code No External Sense Resistor ** = 01 (LC709203FQH01TWG) 2.8% Accuracy of RSOC 02 (LC709203FQH02TWG) Accurate RSOC of Aging Battery 03 (LC709203FQH03TWG) Automatic Convergence of Error 04 (LC709203FQH04TWG) AS = Assembly Location Adjustment for the Parasitic Impedance around the Battery WL = Lot Number Simple and Quick Setup YW = Work Week Low Power Consumption = PbFree Package 3 A Operational Mode (Note: Microdot may be in either location) Precision Voltage Measurement 7.5 mV WLCSP9 Precision Timer 3.5% 203** Alerts for Low RSOC and/or Low Voltage YMXXX Temperature Compensation Sense Thermistor Input 203** = Specific Device Code 2 Via I C ** = 01 (LC709203FXE01MH) 02 (LC709203FXE02MH) Detect Battery Insertion 03 (LC709203FXE03MH) 2 I C Interface (up to 400 kHz Supported) 04 (LC709203FXE04MH) These Devices are PbFree, Halogen Free/BFR Free and are RoHS 05 (LC709203FXE05MH) Y = Year Compliant M = Month Code XXX = Lot Number Applications Wireless Handsets ORDERING INFORMATION Smartphones/PDA Devices See detailed ordering and shipping information on page 19 of MP3 Players this data sheet.
