Overview

Description

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.

TRANSCRIPT

Hi, my name is Andrew Luchsinger, Technical Marketing at IDT, and today I'd like to introduce the P9235A-R. This is a 3W wireless powered 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 preconfigured to function with a 1-watt, 2-watt, or 3-watt coil, ranging in size from 15 millimeters to 30 millimeters in diameter, making it an ideal solution for a variety of compact applications. For more information please visit IDT.com/P9235A-R. Thank you.
