Part Name(s) : DS2434
Description : Battery Identification Chip
Dallas Semiconductor -> Maxim Integrated
DESCRIPTION The DS2434 Battery Identification Chip provides a convenient method of tagging and identifying battery packs by manufacturer, chemistry, or other identifying parameters. The DS2434 allows the battery pack to be coded with a unique identification number, and also store information regarding the battery life and charge/discharge characteristics in its nonvolatile memory.
FEATURES ■ Provides unique ID number to battery packs ■ Eliminates thermistors by sensing battery temperature on-chip ■ 256-bit nonvolatile user memory available for storage of user data such as gas gauge and manufacturing information ■ Operating range of -40°C to +85°C ■ Applications include portable computers, portable/cellular phones, consumer electronics, and handheld instrumentation. ■ Surface-mount package (209-mil SSOP16) available
The bq29330 is a 2-series, 3-series, and 4-series cell lithium-ion battery pack full-protection analog front end (AFE) IC that incorporates a 2.5-V, 16-mA and 3.3-V, 25-mA low dropout regulator (LDO). The bq29330 also integrates an I2C-compatible interface to extract battery parameters such as battery voltage, individual cell voltages, and control output status. Other parameters such as current protection thresholds and delays can also be programmed into the bq29330 to increase the flexibility of the battery management system.
The ISL88731A is a highly integrated Lithium-ion battery charger controller, programmable over the SMBus system management bus (SMBus). The ISL88731A is intended to be used in a smart battery charger (SBC) within a smart battery system (SBS) that throttles the charge power such that the current from the AC-adapter is automatically limited.
The MAX6439–MAX6442 are a family of ultra-low-power battery monitors with integrated microprocessor (µP) supervisors. The battery monitors are offered with single or dual low-battery output options that can be used to signal when the battery is OK (enabling full system operation), when the battery is low (for low-power system operation), and when the battery is dead (to disable system operation).
These devices also have an independent µP supervisor that monitors VCCand provides an active-low reset output. A manual reset function is available to reset the µP with a push-button. No external components are required.
