Texas Instruments (TI) has introduced new lithium-ion battery charger integrated circuits (ICs) that reduce charge time by 50 percent in smartphones and tablets compared to other charger solutions. The bq2419x family of 4.5A output, 20V input-rated switch-mode chargers with I2C interface and USB on-the-go (OTG) support delivers faster and cooler charging to a wide array of applications ranging from power banks and packs to 4G LTE routers, Wi-Fi speakers, portable medical and industrial designs.
Consumers continue to seek faster battery charging in portable electronics. New designs require more accurate, highly-efficient charge circuitry that keeps the system cool and safe while charging at a faster rate. Available in a 24-pin, 4mm x 4mm QFN package, the bq24190, bq24192, bq24192i, bq24193, bq24195, bq24195L and bq24196 fast-charge circuits reduce charge time through battery path impedance compensation, and offer programmable thermal management capability to ensure the safest, most reliable system operation, says the company.
