Texas Instruments has introduced a 3 MHz, switch-mode battery charge management IC for portable electronics, which can be charged from an adaptor or a USB port.
The tiny 2 x 2 mm switching charger, the bq24150, is said to improve charge time, reduce power dissipation and cut board space in half compared to typical implementation with linear chargers.
The device, with integrated 1,25 A FETs, is claimed to be the industry's smallest I²C programmable buck-charger solution, providing excellent battery charging performance and design flexibility in USB-powered applications, such as smart phones, portable media players or other consumer electronics. The charger only requires the use of a tiny 1 μH inductor and small ceramic capacitors, resulting in a solution size of 7,6 x 10,4 mm. The bq24150 also features a reverse boost USB on-the-go (OTG) mode that generates a voltage supply to power accessories that are plugged into a mini-USB port, eliminating the need for another discrete device.
The bq24150 fully complies with USB charging standards. It can achieve high peak efficiency of up to 92%, while supporting a USB battery charging current up to 900 mA. This speeds the charging rate without exceeding the 500 mA input current limit mandated by the USB standard.
The device's USB-friendly boot-up sequence allows the charge IC to boot autonomously, which helps replenish deeply discharged batteries. In addition, it features input current sensing and offers multiple programmable charge parameters through its I²C communications interface.
