Fuel Gauge ICs Enable ‘Highest’ Capacity Measurement

( 1 Nov 2009 )

Texas Instruments Inc. has introduced the bq20z4x and bq20z6x family of battery fuel gauge ICs with enhanced charging, including the Japan Electronics and Information Technology Association (JEITA) profile. The battery fuel gauges feature Impedance Track technology and provide the highest degree of capacity measurement for two- to four-cell battery packs used in next-generation notebooks and netbooks, portable industrial and medical equipment. The bq20z45 and bq20z65 are single-package ICs with integrated battery protection, while the bq20z40 and bq20z60 are dual-package ICs requiring a companion bq29330 analog front-end device. The bq20z6x family supports LED functionality.
