Power & Power Management

Overview

Description

The P9242-R is a highly-integrated 15W magnetic induction wireless power transmitter compliant to the WPC-1.2 specification. The product is designed to withstand a wide input voltage range of 4.25V to 21V, while consuming very low power in standby mode.

The transmitter includes a 32-bit ARM Cortex®-M0 processor, foreign object detection (FOD), full bridge drivers and on-chip simultaneous voltage and current demodulation. The device features a programmable current, programmable LED pattern; and I2C serial interface protocol to read back information such as voltage, current and fault conditions. Together with P9221-R receiver, the P9242-R is a complete wireless power system solution for 15W applications. The P9242-R is available in a , space-saving 6 x 6 mm 48-VFQFPN package. It is rated for -40ºC to +85ºC ambient operating temperature range.

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.
