Innovative Technologies from Texas Instruments

Dynamic Power Path Management (DPPM)
Found in the bqTINY-III, Dynamic Power Path Management (DPPM) powers the system while independently charging the battery. It also reduces the charging current for excessive loads.
Single-Chip Charger and DC/DC Converter
The integration found in the bq25010 combines a battery charger with a low-power, efficient, synchronous DC/DC converter. The chip supports space-limited, Li-Ion powered portable applications, such as Bluetooth headsets & MP3 players.
Impedance Track™
The bq20z70 and bq20z90 battery fuel gauges feature Impedance Track™ which calculates the remaining run-time to within 1% error for the entire life of the battery. Impedance Track enables longer run times by allowing the system to use all the capacity of the battery without experiencing an unexpected low voltage condition and subsequent system shutdown.
System Peripheral Authentication
Authentication techniques in the bq26150, enable the validation of batteries and peripherals, assuring they meet OEM requirements. An encryption transform and a secure device ID are used to generate a unique response to a random challenge from the host system to the peripheral. The host system compares the response to the expected result, enabling authentication.
