The STWLC68JRH is a highly integrated wireless power receiver solution from STMicroelectronics. It is designed to offer an efficient and convenient charging solution for a wide range of applications, including smartphones, tablets, portable devices, and industrial equipment. This receiver is compliant with the Qi wireless charging standard set by the Wireless Power Consortium (WPC), ensuring compatibility with a vast array of wireless charging pads and accessories.
With its built-in synchronous rectifier and low-dropout regulator, the STWLC68JRH boasts high efficiency and optimized power management. This not only extends the battery life of the end device but also ensures cooler operation during charging, which is critical for maintaining the longevity and safety of the electronics.
The device supports an input voltage range of 4.5 V to 21 V, which allows it to handle the fast-charging needs of modern devices. Moreover, it is capable of delivering up to 15W of output power, making it suitable for applications that require quick charging times. The STWLC68JRH also includes an I²C interface, which provides a communication channel between the receiver and the host system, enabling the exchange of critical information such as charging status and error messages.
One of the key features of the STWLC68JRH is its Foreign Object Detection (FOD) functionality. This safety feature detects the presence of metal objects on the charging pad that could interfere with the charging process or pose a safety risk. In such cases, the receiver can halt the charging process to prevent overheating or damage to the device.
The STWLC68JRH is available in a compact WLCSP-34 package, making it ideal for space-constrained applications. Additionally, it is designed with an advanced EMI noise mitigation strategy, ensuring that the device operates quietly and does not interfere with other electronic devices in its vicinity.
In summary, the STWLC68JRH from STMicroelectronics is a sophisticated wireless power receiver that offers high efficiency, fast charging capabilities, and advanced safety features, making it an excellent choice for designers looking to integrate wireless charging into their next-generation products.
