Texas Instruments Inc. (TI) has launched three new switch-mode standalone battery charger ICs for lithium-based battery-powered applications with a 5V to 28V input. The 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.
TI's battery charger ICs 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.
The BQ24610 and BQ24617 are available now in a 24-pin 4x4mm² QFN package. The BQ24600 is available in a 16-pin 3.5x3.5mm² QFN package.
