P9235A-R Wireless Power Transmitter for 0.5W to 3W Applications
The P9235A-R is a 3W, magnetic induction wireless power transmitter IC supporting up to three different coil sizes targeted for ≤3W power applications. The product is designed to withstand a wide input voltage range of 4.5 to 5.5V while consuming only 1mA of current in the standby mode.
The transmitter includes 32-bit ARM® Cortex®-M0 processor, full bridge power stage drivers and on-chip simultaneous voltage and current demodulation. The device supports read-back of voltage, current and fault conditions. The P9235A-R is available in a 40-VFQFPN package (5 × 5 mm), and it is rated for -40 to +85°C temperature range.
The P9235A-R with the P9027LP-R receiver make a complete solution for ≤3W power applications.

Hi, my name is Andrew Luchsinger, Technical Marketing at IDT, and today I’d like to introduce the P9235A-R. This is a three-watt wireless power transmitter optimized for small-form factor applications. The device features a proprietary slew-rate control on the drivers, eliminating the EMI filter components on the input and resulting in very low EMI. The embedded microcontroller functions with extremely-low standby and sleep mode power for maximum efficiency. The device is pre-configured to function with a one-watt, two-watt, or three-watt coil, ranging in size from 15 millimeters to 30 millimeters in diameter, making it an ideal solution for a variety of compact applications.
