The Texas Instruments BQ24705RGET is an active host-controlled battery charger IC designed for multi-chemistry applications. It supports charging of 2, 3, or 4 Li-Ion/Li-Polymer cells, with a maximum charge current of 8A. The device operates within an input voltage range of 5V to 24V, with an absolute maximum rating of 30V.
Key electrical specifications include a charge voltage range of 8V to 18V, with programmable charge voltage per cell from 4V to 4.512V. The charger features high accuracy for voltage and current regulation, with ±0.5% charge voltage accuracy and ±3% charge current accuracy. It utilizes a Switch-Mode Buck control topology and operates at a frequency of 600 kHz, achieving efficiencies greater than 95%.
The BQ24705RGET communicates via the SMBus interface and includes features such as BAT temperature thermistor monitoring, input overvoltage protection, and dynamic power management. It is housed in a compact 24-VQFN (4x4 mm) package, suitable for surface mounting.
This battery charger IC is well-suited for applications including notebook and ultra-mobile computers, portable data-capture terminals, portable printers, medical diagnostics equipment, battery bay chargers, and battery back-up systems.
