Frequently Asked Questions
What wireless charging standard does the BQ500511RHAR support?
The BQ500511RHAR is designed to implement the Qi wireless power standard defined by the Wireless Power Consortium (WPC). Qi is the dominant wireless charging standard for consumer electronics worldwide, used by smartphones from Apple, Samsung, Google, and others. Implementing Qi compliance with the BQ500511RHAR allows transmitter pad designs to charge a wide range of Qi-certified receivers without modifications.
What package does the BQ500511RHAR come in?
The BQ500511RHAR is housed in a 40-pin VQFN (Very Thin Quad Flat No-Lead) square plastic package with JESD-30 code S-PQCC-N40. The QFN package has an exposed metal pad on the bottom for thermal dissipation and a compact footprint suitable for space-constrained charging pad PCB designs. The lead-free construction carries JESD-609 code e4, confirming RoHS compliance.
Does the BQ500511RHAR include foreign object detection?
Yes, the BQ500511RHAR includes foreign object detection (FOD) functionality, which is a mandatory requirement for Qi certification. FOD monitors power loss during wireless charging to detect metallic objects placed on the transmitter coil that could heat up dangerously. When a foreign object is detected, the transmitter stops power transfer to prevent safety hazards, protecting both the charging pad and nearby objects.
What is the YTEOL value for the BQ500511RHAR and what does it indicate?
The BQ500511RHAR has a YTEOL (Years to End of Life) value of 3.9, indicating that the product is projected to remain in active production for approximately 3.9 more years from the data snapshot date. Designers planning new products should verify current lifecycle status directly with Texas Instruments or authorized distributors and consider product lifecycle planning when designing the BQ500511RHAR into new applications requiring long-term support.
What are typical system-level components needed alongside the BQ500511RHAR?
A typical wireless charging transmitter using the BQ500511RHAR requires an external resonant transmitter coil, resonant capacitors, a half-bridge or full-bridge gate driver and FETs for the inverter stage, an AC adapter or USB power source, and filtering capacitors. The IC handles Qi protocol communication, FOD, and coil driver control, while the external power stage components must be selected based on target transmitter power level, efficiency, and form factor requirements.
