Smart LiB Gauge Battery Fuel Gauge LSI For 1‐Cell Lithium‐ion/ Polymer (Li+) LC709203F 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 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 ♦ 3 mA Operational Mode • Precision Voltage Measurement ♦ ±7.5 mV • 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) • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Applications • Wireless Handsets • Smartphones/PDA Devices • MP3 Players • Digital Cameras • Portable Game Players • USB-related Devices www.onsemi.com 1 WDFN8 CASE 509AF WLCSP9 CASE 567JH MARKING DIAGRAMS WDFN8 9203F ** ASWLYW G 9203F** = Specific Device Code ** = 01 (LC709203FQH−01TWG) 02 (LC709203FQH−02TWG) 03 (LC709203FQH−03TWG) 04 (LC709203FQH−04TWG) AS = Assembly Location WL = Lot Number YW = Work Week G = Pb−Free Package (Note: Microdot may be in either location) WLCSP9 203** YMXXX 203** ** Y M XXX = Specific Device Code = 01 (LC709203FXE−01MH) 02 (LC709203FXE−02MH) 03 (LC709203FXE−03MH) 04 (LC709203FXE−04MH) 05 (LC709203FXE−05MH) = Year = Month Code = Lot Number ORDERING INFORMATION See detailed ordering and shipping information on page 19 of this data sheet. © Semiconductor Components Industries, LLC, 2015 January, 2020 − Rev. 16 1 Publication Order Number: LC709203F/D Application Circuit Example T LC709203F 10 kW 10 kW System VDD I2C Bus VDD Master SCL SDA TSENSE TSW PACK− PACK+ Battery Pack LC709203F ASIC TEST VSS VDD ALARMB 10 kW 1 mF System Interrupt Input VSS System VSS Figure 1.

PIN FUNCTION WDFN8 WLP9 Pin Name I/O Description 1 B1 TEST I Connect this pin to VSS. 2 A1 VSS − Connect this pin to the battery’s negative (−) pin. 3 A3 VDD − Connect this pin to the battery’s positive (+) pin. 4 A2 ALARMB O This pin indicates alarm by low output(open drain). Pull-up must be done externally. Alarm conditions are specified by registers (0x13 or 0x14). Connect this pin to VSS when not in use. 5 B3 TSW O Power supply output for thermistor. This pin goes HIGH during temperature read operation. Resistance value of TSW (for thermistor pull-up) must be the same value as the thermistor. (Note 1) 6 C3 TSENSE I Thermistor sense input. If you connect this pin to thermistor, insert 100 W resistance between them for ESD. (Note 1) 7 C1 SDA I/O I2C Data pin (open drain). Pull-up must be done externally. 8 C2 SCL I/O I2C Clock pin (open drain). Pull-up must be done externally. − B2 NC − Don’t care. 9 − Exposed − Don’t care. PAD 1. TSW and TSENSE must be disconnected as Figure 1 when not in use. Table 2.
