TI switch-mode standalone battery charge controllers provide faster, cooler charging for 5-V to 28-V applications

bq24600, bq24610 and bq24617 offer high charging efficiency and accuracy for optimal battery life cycle

PRNewswire
Mar 10, 2010

DALLAS, March 10 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced three new switch-mode standalone battery charger ICs for lithium-based battery-powered applications with a 5-V to 28-V input. These devices provide highly accurate and efficient charging in a small package for mass market applications, such as industrial handhelds, mobile Internet devices (MIDs), netbooks, power tools and portable medical devices. For product details, see: www.ti.com/bq24600-pr, www.ti.com/bq24610-pr, and www.ti.com/bq24617-pr.

These devices offer a constant-frequency synchronous switching pulse-width modulation (PWM) controller with highly accurate charge current and voltage regulation, charge preconditioning, termination, adapter current regulation and charge status monitoring. The battery is charged in three phases: preconditioning, constant current and constant voltage. A programmable charge timer provides a safety backup.

Key features and benefits

  • Higher efficiency results in less heat dissipation than other solutions.
  • Greater than 99 percent charge voltage and current accuracy optimize battery life cycle.
  • Integrated, standalone solution enhances design flexibility and reduces overall solution size.
  • Dynamic power management maximizes use of adapter power to power the system while charging the battery.

Availability and pricing

The bq24610 and bq24617 are available now in a 24-pin 4x4 mm2 QFN package. The bq24600 is available in a 16-pin 3.5 x 3.5 mm2 QFN package. The bq24610 is priced at $2.60 and the bq24600 and bq24617 are priced at $2.90, in quantities of 1,000.  

New battery charger selection tool helps speed selection process

TI provides a broad range of battery charger ICs that support single-cell and multi-cell battery packs used in handheld, portable medical and portable industrial equipment. Designers can select recommended products using TI's new Battery charger selector tool, where one can choose criteria based on battery chemistry, number of cells, topology needed and battery voltage levels.
