Product Details

Battery Monitor/Fuel Gauge, Texas Instruments

The battery charge monitoring system is the component responsible for determining the energy remaining in the battery. It provides information such as remaining battery capacity (mAh), state-of-charge (%), and battery voltage (mV). It minimises dependence on host processor and improves standby power.

Safety protections such as over/under-​temperature, extra levels of over/under-voltage, discharge short circuit, charge overcurrent
Autonomously measures all cell voltages, integrated pack current and temperature every 1 second
Capacity Indication with advanced algorithms
Accurate battery State-Of-Health (SOH) enables accurate prediction of available capacity
Smart charging and adaptability
