The P9241-G is a highly integrated, magnetic induction wireless power transmitter that supports Wireless Power Consortium (WPC) Qi specification Baseline Power Profile (BPP) and proprietary fast charging modes, including 7.5W for iPhone and up to 10W for Android phones. The P9241-G supports WPC power transmitter design A11a coil configuration.
The P9241-G transmitter generates power through the power coil, detects the presence of a wireless power receiver, decodes the communication packets from the receiver, and adjusts the transmitted power by controlling the voltage based on the feedback from the receiver. The device offers superior Foreign Objects Detection (FOD), which is critical to guarantee a safe operation when transferring power wirelessly.
The P9241-G integrates a 32-bit ARM® Cortex®-M0 processor, offering a high level of programmability with extremely low standby power. Integrated current sense amplifier, full bridge MOSFET drivers and bias regulators reduce the discrete component count and offer a compact solution ideal for mobile applications.
The device is highly configurable with GPIO pins and I2C serial communication channels. Two pre-defined user-programmable LED outputs offer various blinking patterns for user indication. The external step down regulator in the front end of P9241-G design enables wide input voltage range of 5V to 19V. The device also operates at a fixed-frequency, 127.7kHz, to support 7.5W charging for Apple iPhones.
The P9241-G offers a wide range of system protection features, such as over-current, over-voltage, under-voltage lockout, and thermal management to safe guard wireless power systems under fault conditions.
The device is available in a lead-free, space-saving 48-VFQFPN package and rated for a wide operating temperature range of -40ºC to +85ºC.
Pair it with the P9225-R wireless power receiver for a complete wireless charging system solution.

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.
