Description
The bq20z45 SBS-compliant gas gauge and protection IC is a single IC solution designed for battery-pack or in-system installation. The bq20z45 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analog peripherals, monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack as well and reports the information to the system host controller over a serial-communication bus.
Key Features
- Supports the Smart Battery Specification SBS V1.1
- Flexible Configuration for 2 to 4 Series Li-Ion and Li-Polymer Cells
- Powerful 8-Bit RISC CPU With Ultralow Power Modes
- Full Array of Programmable Protection Features – Voltage, Current, and Temperature
- Satisfies JEITA Guidelines
