IDT Introduces Industry’s First Single-chip 5V Wireless Power Transmitter Solution

Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced the industry’s first Qi-compliant single-chip wireless power transmitter solution supporting a 5V input. The highly-integrated solution enables the development of USB-powered wireless charging bases with 75% fewer ICs than competing solutions. IDT’s transmitter solution is ideal for use in wireless charging systems that seek to take advantage of a universal power port while minimizing system complexity and physical size.

The IDTP9038 is a single-chip wireless power transmitter IC compatible with the Wireless Power Consortium (WPC) 1.1 “Qi” standard for A5 and A11 coil configurations, enabling OEMs to develop charging bases that are fully compatible with any Qi-compliant portable device. The device operates with a 5V input, allowing it to be powered by any standard USB port, USB wall adapter, or traditional 5V adapter. Such ports and adapters are ubiquitous and already included with many popular portable electronics, streamlining the user experience and reducing solution cost. In addition, IDT’s device is designed as a single high-efficiency IC, whereas existing solutions require four or more ICs. This enables system designers to minimize system complexity, ease PCB routing constraints, and simplify the bill-of-materials.

“IDT continues to lead the market with the industry’s most integrated and feature-rich wireless power solutions,” said Arman Naghavi, vice president and general manager of the Analog and Power Division at IDT. “The IDTP9038 empowers our customers to create USB-powered wireless charging mats that use the same USB adapters they already bundle with their portable devices, or that can be plugged into a laptop or docking station for convenience. In addition, our highly-integrated solutions benefit customers by minimizing system complexity, easing PCB routing challenges, and simplifying the BOM – all factors that help ensure a successful product development and, ultimately, improve time-to-market.”

The IDTP9038 features an embedded microcontroller and integrated full-bridge inverter with low-resistance FETs for exceptional flexibility, minimized PCB real estate, and high-efficiency power transfer. IDT’s patent-pending control circuit offers world-class EMI performance measured at 15 dB lower than CISPR requirements, reducing concerns of cross-talk with other sensitive electronics. The 5V device features USB connectivity meeting the requirements of BCS 1.2 (D+/D- detection) for fully controlled power delivery and added safety.

In addition, the IDTP9038 features a proprietary high-power transfer mode capable of delivering up to 60% more power than specified by the Qi standard – transmitting up to 8 watts of power when paired with an IDT wireless power receiver. This enables OEMs to offer ultra-fast charging times between their IDT-equipped portable devices and IDT-equipped charging mats.

Product Availability

The IDTP9038 is currently sampling to qualified customers and is available in a standard 7x7 mm 56-ld VFQFN package. Evaluation boards, layout guides, and other support tools are available to ease the design-in process.
