Product Description

The BQ26220PW is a flash-based precision multi-chemistry Charge/Discharge Counter with voltage measurement. It is designed to accurately measure the charge and discharge currents in rechargeable battery packs. Intended for pack integration, the BQ26220 contains all the necessary functions to form the basis of a comprehensive battery capacity management system in portable applications such as cellular phones, PDA"s, or other portable products. It works with the host controller in the portable system to implement the battery management system. The host controller is responsible for interpreting the charger data and communicating meaningful battery data to the end-user or power management system. This device provides 64 bytes of general-purpose flash memory, 8 bytes of ID ROM and 32 bytes of flash-backed RAM for data storage.
Internal temperature sensor eliminates the need for an external thermistor
Programmable digital input/output port
High-accuracy internal timebase eliminates external crystal oscillator
Low power consumption
Differential current sense
Provides state of charge information for rechargeable batteries
Provides accurate battery voltage and temperature measurement
Green product and no Sb/Br
