1 / 31 page  Wireless Power Transmitter for 15W Applications P9242-R Datasheet © 2016 Integrated Device Technology, Inc 1 December 16, 2016 Description The P9242-R is a highly integrated, magnetic induction, wireless power transmitter supporting up to 15W. The system-on-chip operates with an input voltage range of 4.25V to 21V. The transmitter includes an industry-leading 32-bit ARM® Cortex®-M0 processor offering a high level of programmability while consuming extremely low standby power. The P9242-R features two LED outputs with pre-defined user-programmable blinking patterns, buzzer, and programmable over-current protection supporting a wide range of applications. The I2C serial communication allows the user to read information such as voltage, current, frequency, and fault conditions. The P9242-R includes an under-voltage lockout and thermal management cir- cuit to safe guard the device under fault conditions. Together with the P9221-R receiver (RX), the P9242-R is a complete wireless power system solution. The P9242-R is available in a lead-free, space-saving 48-VFQFN package. The product is rated for a -40ºC to +85ºC operating temperature range.
