The P9242-G is a highly integrated, magnetic induction, wireless power transmitter supporting applications up to 15W. The system-on-chip device (P9242-G) operates with an input voltage range of 5V to 19V. The P9242-G converges all popular wireless charging protocols including WPC Baseline Power Profile (BPP), Extended Power Profile (EPP), up to 7.5W charging for iPhone, and Android proprietary fast charging modes. 

The P9242-G includes an industry-leading 32-bit ARM® Cortex®-M0 processor offering a high level of programmability while consuming extremely low standby power. The transmitter features two LED outputs with pre-defined user-programmable blinking patterns, buzzer, and programmable over-current protection supporting a wide range of applications. The device is designed to support a fixed frequency operation compliant to WPC MP-A11 coil configurations. It uses an external oscillator for very accurate 127.7kHz fixed frequency operation. The I²C  serial communication allows the user to read information such as voltage, current, frequency, and fault conditions. 

The P9242-G includes an under-voltage lockout and thermal management circuit to safeguard the device under fault conditions. Together with the P9221-R receiver (RX), the P9242-G forms a complete wireless power system solution.

The P9242-G is available in a lead-free, space-saving 48-pin VFQFPN package. The product is rated for a -40ºC to +85ºC operating temperature range.
