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.

The development platform for i.MX 6Quad from element14 (built to the Freescale SABRE Lite design) is an evaluation platform featuring the powerful i.MX 6Q, a multimedia application processor with Quad ARM Cortex-A9 cores at 1.2 GHz from Freescale Semiconductor.
This month, Freescale and element14 are giving away five such platforms, worth £128.06 each, for EETimes Europe's readers to win. The platform helps evaluate the rich set of peripherals and includes a 10/100/Gb Ethernet port, SATA-II, HDMI v1.4, LVDS, parallel RGB interface, touch screen interface, analog headphone/microphone, micro TF and SD card interface, USB, serial port, JTAG, camera interface, and input keys for Android.
And the winners are...
In our previous reader offer, Pico Technology was giving away one of its recently launched PicoScope 3207B, a 2-channel USB 3.0 oscilloscope worth 1451 Euros. Lucky winner Mr L. Sanchez-Gonzalez from Spain should be receiving his PicoScope 3207B soon. Let's wish them some interesting findings with his projects.
