Overview
Description
The RA9530 is a highly-integrated single-chip wireless power transmitter/receiver IC (TRx). The device can be configured to receive or transmit an AC power signal through magnetic induction.
The RA9530 integrates a high-efficiency Synchronous Full Bridge Rectifier and control circuitry to modulate the load to send message packets to the Transmitter (Tx) to optimize power delivery. Wireless power transfer is managed by an integrated 32-bit ARM® Cortex®-M0 processor offering a high level of programmability while consuming extremely low standby power. The processor can also control GPIOs to indicate operating and fault modes.
The RA9530 features EEPROM or non-volatile memory that enables customers to customize the design parameters such as default FOD thresholds and implement over-the-air (OTA) control firmware updates. It is available in an ultra-small 48-DSBGA package.

IDT Overview & Wireless Charging
IDT develops and sells a broad range of semiconductors that are used in a wide variety of industrial applications and consumer products. Established in Silicon Valley in 1980, IDT employs 1,500 people worldwide. The company's chips are used to enable today's mobile Internet. In fact, virtually every 3G and 4G phone call made around the world goes through IDT products. IDT's semiconductors play an essential role in today's advanced technology. Its market leading timing devices, for example, serve as the heartbeat of electronic systems. Another one of its products is helping scientists at CERN move, manage, and make sense of the vast amounts of data gathered from experiments at the Large Hadron Collider.
Always on the cutting edge, IDT is also the leader in wireless charging. Wireless charging delivers cord free convenience for today's consumer products and is a great differentiator for highly competitive markets. The company's wireless power transmitters and receivers are currently in use by countless consumers in smartphones, wearables, charging stations, computer monitors, lamps, remote controls, and furniture. IDT recently introduced wireless charging kits, removing much of the cost and engineering expertise previously required to integrate wireless charging into consumer products. Wireless charging is just the latest way IDT is helping make life a little easier for us all.
