The IDTP9024, IDTP9025A, and IDTP9028 are fully-integrated, single-chip wireless power receivers supporting PMA, WPC Qi 1.1, and dual mode (PMA and Qi) standards, respectively. The devices utilise a high-efficiency low-dropout regulator (LDO)-based architecture to minimise component count, resulting in significant savings in board area and bill-of-materials (BOM) cost. In addition, optimized control logic minimises power losses to ensure highly-efficient power delivery to the load.
The space- and cost-optimised wireless power receivers are ideal for wireless handsets, cell phone sleeves, and tablets.
All three wireless power receivers integrate a high-efficiency synchronous full bridge rectifier, high-efficiency LDO, and advanced control circuits in a single-chip. These functions work together with a thin receiver coil to wirelessly receive power from a compatible transmitter and provide a well-regulated 5 V output for powering and charging portable electronics.
The IDTP9024 and IDTP9025A enable the development of portable devices that are fully compatible with any PMA- or Qi-compliant transmitter, respectively.
For maximum versatility, the IDTP9028 offers seamless dual-mode capability, switching between the Qi and PMA protocols and negotiating the power exchange without user intervention. The high-level of integration greatly simplifies the system architecture, enabling designers to complete their designs with minimal effort, while proven standards compliance ensures a user-friendly experience.
