TEXAS INSTRUMENTS bq2058 handbook(1)
bq2058 is a lithium ion battery pack supervisor that protects and individually monitors 3 or 4 series lithium ion (Li-Ion) cells for overvoltage, undervoltage and overcurrent. It is designed for battery pack integration, has minimal external components, drives external FET switches and has selectable overvoltage (VOV) thresholds.

Texas lnstruments bq2052 handbook
The bq2052 Lithium Primary Gas Gauge IC is intended for battery-pack or in-system installation to maintain an accurate record of available battery capacity. The IC monitors a voltage drop across a sense resistor connected in series with the cells to determine discharge activity of the battery. The bq2052 applies compensations for battery temperature and discharge rate to the available charge counter to provide available capacity information across a wide range of operating conditions. Compensated available capacity may be directly indicated using an LED display. The LED display is programmable and can be configured as two, four, or five segments. These segments are used to depict available battery capacity. The bq2052 supports a single-wire serial communications link to an external micro-controller. The link allows the micro-controller to read

Texas lnstruments bq2040EVM handbook
Texas lnstruments bq2040 handbook
The bq2040 gas gauge IC with SMBus interface is intended for battery pack or in-system installation to maintain an accurate record of available battery charge. The bq2040 directly supports capacity monitoring for NiCd, NiMH, and Li-Ion battery chemistries. The bq2040 uses the System Management Bus v1.0 (SMBus) protocol and supports the Smart Battery Data (SBData) commands. The bq2040 also supports the SBData charge control functions. Battery state-of-charge, remaining capacity, remaining time, and chemistry are available over the serial link. Battery-charge state can be directly indicated using a four-segment LED display to graphically depict battery full-to-empty in 25% increments. The bq2040 estimates battery self-discharge based on an internal timer and temperature sensor and user-programmable rate information stored in external EEPROM. The bq2040 also automatically re-calibrates or “learns” battery capacity in the full course of a discharge cycle from full to empty.
Texas lnstruments bq2031 handbook
The bq2031 is a lead-acid battery fast charge ic that can achieve constant voltage, constant current or pulsed current charging, and can set the regulator frequency by an external capacitor for design flexibility. The switch-mode design keeps power dissipation to a minimum, suitable for high charge current applications. A charge cycle begins when power is applied or the battery is replaced. For safety, charging is inhibited until the battery voltage is within the configured limits.
TEXAS INSTRUMENTS bq2023 handbook
This 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.
