BQ2023 描述

The bq2023 is an advanced battery monitoring IC that accurately measures the charge and discharge currents in rechargeable battery packs. Intended for pack integration, the bq2023 contains all the necessary functions to form the basis for an accurate battery gas gauge in cellular phones, PDAs, or other portable products. Gas gauging is accomplished by coulomb counting (i.e., measuring the charge input to and subsequently removed from the battery). The bq2023 achieves that by measuring the differential voltage drop across a low-value series sense resistor between the negative terminal of the battery and the battery-pack negative contact. An internal voltage-to-frequency converter (VFC) converts this voltage into charge and discharge counts
