  • Dual-mode, 5-watt receiver: Compliant with Qi 1.1 and PMA communication and control.
  • High efficiency for fast charge time: Achieves up to 96 percent power efficiency, and the device's adjustable output voltage helps reduce power loss by as much as 50 percent.
  • Industry's smallest, thinnest solution: 3.6-mm by 2.9-mm by 0.5-mm single-chip wireless power receiver achieves a solution size of 75 mm 2 without the need for an inductor.

In addition to the dual-mode receiver, TI also introduced its bq51010B next-generation Qi 1.1-compliant receiver with an integrated 7-V regulated supply and foreign object detection.
