Description:The P9235A-RB is a highly integrated, magnetic induction, wireless power transmitter supporting up to 5W of total wireless system power. The P9235-RB offers a pre-programmed bootloader that must be used in conjunction with an external flash memory that contains control firmware. This architecture gives user a flexibility to change the firmware in the external flash to meet application specific requirements. IDT also provides firmware to implement standard WPC coil configurations such as the A11a.The P9235A-
A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the center of the board, and the input and output capacitors should be placed close to the device. A minimum of 10 mils of clearance should be maintained between the device and other components.
To ensure stability, the output voltage should be decoupled with a minimum of 10uF ceramic capacitor and a 1uF ceramic capacitor in parallel. The capacitors should be placed close to the output pins and the device should be operated within the recommended input voltage range.
The maximum ambient temperature range for the P9235A-RBNDGI8 is -40°C to 125°C. However, the device should be derated for temperatures above 85°C to ensure reliable operation.
Yes, the P9235A-RBNDGI8 is suitable for high-reliability applications. It is manufactured using a robust process and has undergone rigorous testing to ensure its reliability. However, it is recommended to follow the recommended operating conditions and to perform thorough testing and validation for the specific application.
To troubleshoot issues with the P9235A-RBNDGI8, first check the input voltage and ensure it is within the recommended range. Then, check the output voltage and ensure it is within the expected range. If the issue persists, check the PCB layout and ensure it meets the recommended layout guidelines. If the issue still persists, contact Renesas Electronics Corporation support for further assistance.
