First dual-mode 5-W wireless power receiver enters volume production
The new bq51221 inductor-less, 5-watt receiver’s high efficiency and programmable output reduces power loss by as much as 50 percent compared to existing receiver solutions, allowing consumers to more efficiently and quickly charge their mobile phones, headsets and power banks from a Qi or PMA charging station.
In addition to the dual-mode receiver, TI has also introduced the company’s bq51010B next-generation Qi 1.1-compliant receiver with an integrated 7-V regulated supply and foreign object detection. The single-chip receiver, also shipping in volume production, achieves 93 percent power efficiency and ensures the lowest possible power dissipation when charging a Qi-compliant smartphone.
Availability and pricing
The bq51221 and bq51010B wireless power receivers are available in volume production to customers worldwide. The bq51221 dual-mode receiver comes in a 42-pin, 3.6-mm by 2.9-mm by 0.5-mm package at a suggested resale price of $3.00 each in 1,000-unit quantities. Qi-only versions of the bq51221 are currently sampling to select customers, and are expected to be available in volume production in the second quarter. Designers can order the new bq51221EVM-520 evaluation module to get started on dual-mode wireless power receiver designs.
