Stand-alone batteriladere

Texas Instruments lancerer switch-mode stand-alone batterilader controllere til  5V til 28V applikationer (in english).

Texas Instruments (TI) introduces three new switch-mode stand-alone 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.

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.
