Product Details

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.

Low power consumption : 3 μA Operational mode
Precision Voltage measurement : ±7.5 mV
Precision Timer : ±3.5%
Alerts for Low RSOC and / or Low Voltage
Temperature compensation :Sense Thermistor inputVia I2C
Detect Battery insertion
I2C Interface (up to 400 kHz supported)
