Wireless Power Transmitters P9235 and P9236 by IDT



Introduction to a new family of magnetic induction wireless power transmitters designed for the next generation of wireless charging products, delivering greater flexibility and ease of use while reducing overall development cost through a high level of integration. As an expansion to an existing broad portfolio of products, the ultra-compact transmitters feature low electromagnetic interference (EMI) and high efficiency, making them ideal for a wide variety of applications, including wearables, smart phones and furniture.
The P9235 and P9236 transmitters are compliant with the latest Wireless Power Consortium (WPC) Qi 1.1.2 standard. Featuring an integrated 32-bit ARM® Cortex®-M0 processor, the P923x family offers a high level of programmability and flexibility while consuming ultra-low standby power to meet Energy Star requirements.  The transmitters span input voltages ranging from 4.0 V to 21 V and target applications requiring from 0.5 to 10W  of power. In addition, the devices offer a high level of integration, including all digital and analog functions, which minimizes the number of external components while reducing overall system cost.

Hi, my name is Andrew Luchsinger, technical marketing manager at IDT. Today, I’d like to briefly introduce the P9235 and P9236 wireless power transmitters. These are compact high efficiency, and highly flexible wireless power transmitters compliant to the WPC 1.1.2 specification. One of the coolest things about these parts is the fact they feature an integrated 32 bit ARM Cortex-M0 processor making them highly programmable, but consuming really low standby power to meet energy star requirements. The transmitters work with input voltages ranging from four volts all the way up to 21 volts, with power transfer capability from half a watt up to 10 watts making them ideal for applications such as wearables, smart phones, and furniture.

Specifically, The 9235 features a full bridge rectifier, and supports WPC’s A5 and A11 single-coil transmitter configurations. It comes in a 5x5 mm 40-lead package. The P9236 is a half bridge device supporting WPC’s A6 single and multi-coil transmitter configurations. It’s offered in a 6x6 mm 48-lead package.
