Key Features of the BQ40Z555RSM IC

High-accuracy state-of-charge (SOC) estimation

The BQ40Z555RSM IC gives very accurate SOC readings. It figures out how much battery power is left. It does this by combining charge counting and voltage checks. This method stays reliable even as the battery gets older. The IC keeps track of charge going in and out of the battery. It also updates its calculations during full charges or discharges to stay precise.

Note: Knowing the SOC helps users plan battery use better.

This feature is important for devices like medical tools and industrial machines. These need batteries to work well all the time.

Impedance Track technology for enhanced accuracy

Texas Instruments added Impedance Track technology to the BQ40Z555RSM IC. This special system improves SOC accuracy by checking battery resistance. As batteries age, their resistance increases, which can lower performance. Impedance Track adjusts for these changes, keeping readings correct over time.

• How it works:

  1. The IC measures battery resistance as it works.

  2. It updates SOC readings based on the resistance.

  3. This keeps results accurate, even with changing power use.

This technology makes the IC great for devices needing long-lasting batteries.
