BQ25910YFFT Product Details

Texas Instruments' bq25910 is an integrated three-level switch-mode parallel battery charge management device for single cell Li-ion and Li-polymer batteries. Utilization of the three-level converter maintains highest switch-mode operation efficiency while reducing solution footprint and increasing power density. The device supports fast charging with high input voltage for a wide range of portable devices. The solution integrates reverse-blocking FET (QBLK), and four switching FETs (QHSA, QHSB, QLSB, QLSA). The I2C serial interface with charging and system settings makes the device a truly flexible solution.<strong>Features:</strong> Parallel charger operation provides fast charging in dual charger configuration High efficiency 750 kHz switch mode three-level buck parallel charger, Reduced ripple to support low profile inductor, 95.4% charge efficiency at 1.5 A from 5 V input, 93.3% charge efficiency at 3 A from 9 V input, Superior efficiency compared to traditional buck converter in compact form factor, High integration includes all MOSFETs, current sensing and loop compensation, Lossless charge current sensing without sense resistor, Single input to support USB input and adjustable high voltage adapters Support 3.9 V to 14 V input voltage range with 20 V absolute maximum input voltage rating, Input current limit (500 mA to 3.6 A with 100 mA resolution) to support USB 2.0 and USB 3.0 standard and high voltage adapters, Maximum power tracking by input voltage limit (VINDPM) up to 14 V, Flexible I2C mode for optimal system performance, <10 µA low battery leakage current during standby mode, Smartphones, Tablets, Wireless charging, Portable electronics, Electronic point of sales (ePOS)
