TI Integrates Smart Battery And Power Management On Single Chip

Texas Instruments Incorporated announced a power conversion integrated circuit (IC) with "smart charging" capability that incorporates all essential power transistors onto a single device. Occupying up to 70 percent less board space versus discrete solutions, the programmable chip delivers high DC/DC conversion efficiency and battery management to one-cell Li-Ion powered communication and multimedia devices with multiple voltages, such as smart phones, portable audio and media players, satellite radio and GPS systems.

TI's TPS65800 power management unit integrates several power control building blocks, including two synchronous step-down DC/DC converters with integrated FETs, one boost DC/DC converter for white LED display backlight, an RGB LED driver, seven linear regulators (LDOs), a high-performance analog-to-digital data converter, SIM card and RTC power supplies and an I2C communications interface that allows full programmability of the TPS65800. In addition to the power regulation blocks, the device applies TI's patented linear charge and system power path management technology for Li-ion batteries using integrated charge FETs.

The TPS65800 is currently sampling and is scheduled to be available in volume production later this year from TI and its authorized distributors. The TPS65800 power management unit comes in 56-pin, 8x8mm QFN package, and is priced at $6.50 each in quantities of 1,000 units. Evaluation modules of the TPS65800, application notes and TI's online power management product selection tool are available through power.ti.com.
