Switch-mode standalone battery charge controllers provide faster, cooler charging
March 11, 2010 // Paul Buckley
Texas Instruments Incorporated has introduced three new switch-mode standalone battery charger ICs for lithium-based battery-powered applications with a 5-V to 28-V input.
The devices provide 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.
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 US Dollars and the bq24600 and bq24617 are priced at 2.90 US Dollars, in quantities of 1,000.
