P9235A-RB Datasheet | Renesas

Description The P9235A-RB is a highly integrated, magnetic induction, wireless power transmitter supporting up to 5W of total wireless system power with in-band, bi-directional data munication requiring no additional circuitry. The P9235A-RB 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. The P9235A-RB includes an industry-leading 32-bit ARM® Cortex®-M0 processor offering a high level of programmability while consuming extremely low standby power. The transmitter features two open-drain LED outputs with pre-defined blinking patterns and five general-purpose input/output (GPIO) pins. The GPIOs can be firmware-defined for functions such as setting the current limit, setting FOD limits, driving additional coils, or sounding a buzzer, which supports a wide range of applications. The I2C serial munication allows the user to read information such as voltage, current, frequency, and fault conditions. The P9235A-RB includes an under-voltage lockout and thermal management circuit to safeguard the device under fault conditions. Together with the P9225-R receiver (RX), the P9235A-RB forms a plete 5W wireless power system solution with bi-directional data munication. 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 -40ºC to +85ºC. Application Diagram Ext.
