Renesas Electronics P9235A-RBNDGI, Battery Charger IC, 5 V 40-Pin, 40-VFQFPN

The Renesas Electronics wireless power transmitter is a highly integrated, magnetic induction, supporting up to 5W of total wireless system power with in-band, bi-directional data communication requiring no additional circuitry. It offers a pre-programmed bootloader that must be used in conjunction with an external flash memory that contains control firmware. This architecture allows the user to change the firmware in the external flash to meet application-specific requirements. Renesas also provides firmware to implement standard WPC coil configurations, such as the A11a addendum.

It includes an industry leading 32-bit ARM Cortex M0 processor
The transmitter features two open drain LED outputs with pre-defined blinking patterns
It consists of five general purpose input/output (GPIO)pins
The GPIOs can be firmware defined for functions which supports a wide range of applications
The I2C serial communication allows the user to read information
It includes an under-voltage lockout and thermal management circuit to safeguard the device under fault conditions
Together with the receiver (RX) the P9235A-RB forms a complete 5W wireless power system solution with bi-directional data communication.
It is available in a Pb-free and space-saving 5 x 5 mm 40-VFQFPN package
The product is rated over an operating temperature range of -40ºC to +85ºC
