Frequently Asked Questions
What is the maximum power output of STWBC86JR and which wireless charging standard does it follow?
The STWBC86JR supports up to 5W output power and is compatible with the Qi inductive wireless charging standard, ensuring interoperability with Qi-certified receivers used in smartphones and wearables. This 5W limit aligns with Qi baseline power profile requirements, making it suitable for standard charging accessories without the additional complexity of proprietary fast-charge protocols.
How does the integrated linear battery charger in STWBC86JR reduce system BOM in a wireless charging pad design?
By combining the wireless power transmitter and a linear battery charger with adjustable threshold on a single die, STWBC86JR eliminates a separate charge management IC and its associated passive components, potentially saving 5 to 10 components per design. This integration reduces PCB area, simplifies firmware, and cuts procurement cost for single-cell Li-ion battery applications in IoT devices and smart accessories.
For a slim wireless charging mat design, how does the 72-ball BGA package of STWBC86JR help achieve a low-profile PCB?
The 72-ball BGA measures 8 mm x 9 mm with a 1 mm ball pitch, offering a smaller footprint than equivalent SOIC or QFP packages while placing all 72 I/O connections directly underneath the die for shorter power traces. This geometry allows the charging mat PCB to remain under 1.6 mm thick while accommodating the necessary decoupling capacitors and coil driver circuitry beside the IC.
What is the typical lead time for STWBC86JR and how should procurement be planned for a new product launch?
The factory lead time for STWBC86JR is 20 weeks, which requires ordering at least 5 months before the production start date for a new product. Design teams should place buffer stock orders of at least 1.2x the initial build quantity during the prototype phase to protect against supply chain delays common for BGA-packaged wireless charging ICs.
