LC709209FXE-01TBG, Battery Management FUEL GAUGE
Power\Power Management ICs\Battery Management
LC709209F is a fuel gauge for 1-cell lithium-ion/polymer batteries. 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-CVR2. The device also supports battery safety by alarm functions and SOH (State of Health) reporting to the application processor. The operating consumption current of 2A is very low, making it suitable for applications such as wearables and 1series N parallel batteries. Typical applications are battery packs, wearables/IoT devices, smartphones/PDA devices, digital cameras, portable game players, USB-related devices.
• Small footprint: no need for current sensing resistor
• Accurate RSOC of aging battery, stable gauging by automatic convergence of error
• Immediate accurate gauging after battery insertion, eliminates learning cycle
• Low power consumption, 2µA operational mode current
• Store the initial setting values required for gauging in the built-in non volatile memory
• Continue gauging even after sudden power down
• Improvement of the battery safety by alarm function RSOC/voltage/temperature
• Battery lifetime measurement SOH/cycle count/operating time
• Remaining time estimation time to full/time to empty
• Input to sense an NTC thermistor, Via I²C
