Package : 44-Pin TSSOP (DBT) Type
Manufacturers : Texas Instruments
Pinouts :
Description :
The bq34z950 SBS-compliant gas gauge and protection IC, incorporating patented Impedance Track technology, is a single IC solution designed for battery-pack or in-system installation.
The device measures and maintains an accurate record of available charge in Li-Ion or Li-Polymer batteries using its integrated high-performance analog peripherals. The bq34z950 monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack which reports the information to the system host controller over a serial-communication bus. SMBus and single-wire DQ communication interfaces are both available.
Together with the integrated analog front-end (AFE) short-circuit and overload protection, the IC maximizes functionality and safety while minimizing external component count, cost, and size in smart battery circuits.
Features :
1. Supports the Smart Battery Specification SBS V1.1
2. Optional DQ Communication Interface
3. Powerful 8-Bit RISC CPU with Ultralow Power Mode
4. Added Flexibility to Handle More Complex Charging Profiles
Applications :
1. Notebook PCs
2. Medical and Test Equipment
3. Portable Instrumentation
