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.

P9242-R and P9242-R3 Mismatch solutions
We have just received a batch of PCBs with the P9242-R transmitter chip, and due to a mix-up/oversight the actual part number of the chip used is P9242-RBNDGI8 instead of P9242-RNDGI8. This means the chip is bootloader only and is useless unless programmed. To ...
