Texas Instruments (TI) recently introduced the bq27421, a Li-Ion battery fuel gauge integrated circuit which boosts battery run-time in portable medical devices, such as wearable health monitors, and industrial devices like inventory scanners and portable emergency lights and other consumer electronics.

Leveraging TI's proven Impedance Track advanced battery technology typically used in tablets and smartphones, the bq27421 system-side fuel gauge in a 9-ball chipscale (WCSP) package accurately reports remaining battery capacity, state-of-charge and battery voltage, allowing portable devices to extend run-time by 50 per cent or higher.

"Users of portable medical and other electronics need an accurate prediction of remaining battery capacity to better manage their mobile device and decide when to recharge or replace the battery. Whether it's a blood glucose meter, wearable patient monitor bracelet or portable inventory scanner, you need accurate information to make good decisions," said Steve Lambouses, vice president of battery management. "TI's fuel gauges give consumers the battery information they can depend on, maximising the level of convenience with their battery-powered devices and allowing them to get more run-time out of their batteries."

The bq27421 battery fuel gauge is available in a 1.5x1.5x0.5mm, 9-ball WCSP package.
