Overview
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-RB includes an under-voltage lockout, Foreign object detection (FOD) and thermal management circuit to safeguard the device under fault conditions. Together with the P9225-R receiver (RX), the P9235A-RB forms a complete 5W wireless power system solution.
The P9235A-RB is available in a Pb-free, space-saving 5 × 5 mm 40-VFQFPN package. The product is rated over an
operating temperature range of -40°C to +85°C.
