Power: Battery Management

There are three main components to battery management:

  • Charge Management -
    Charge management ICs integrate all functionality required to safely charge rechargeable batteries to maximize capacity and minimize charge time.
  • Battery Fuel Gauging -
    Battery fuel gauge ICs allow the system to acquire the exact state of battery charge. The information from a TI battery fuel gauge IC can form the basis of a complete power management routine in a portable system, enabling the system to extend its run time.
  • Battery Protection -
    Li-Ion battery packs need protection from overcharge or over discharge conditions. TI's line of protection ICs offer protection for 1-to-4 series Li-Ion battery packs. In some cases, a TI Li-Ion protection IC can work with a TI battery fuel gauge IC to offer a comprehensive battery fuel gauge/protection solution.
