P9235A-R Datasheet | Renesas

Wireless Power Transmitter for ≤3W Applications Description The P9235A-R is a 3W, magnetic induction, wireless power transmitter for low power applications. The system-on-chip operates with an input voltage range of 4.5 - 5.5V while integrating micro-controller, voltage regulation, over-current protection, full bridge power stage drivers and on-chip simultaneous voltage and current demodulation. The transmitter includes industry-leading 32bit ARM® Cortex®M0 processor offering a high level of programmability, while consuming extremely low standby power. The device Features two LED outputs with pre-defined user programmable blinking patterns, buzzer and programmable over-current protection supporting wide range of applications. The I2C serial munication allows the user to read back information such as voltage, current, frequency and fault conditions. Together with the P9027LP-R receiver, the P9235A-R is a plete wireless power system solution. The P9235A-R is available in a Pb-free, space-saving VFQFN 5 mm X 5 mm, 40 pin package. The product is rated over an operating temperature range of -40ºC to +85ºC. Typical Applications - Smart Watches - Headsets - Health and Fitness monitors - Portable Medical applications Features - VIN range: 4.5 - 5.5 V - Supports receiver for up to 3W of power transfer - 80% peak efficiency (when coupled with P9027LP receiver) - Integrated power stage drivers - Low standby power - Simultaneous voltage and current demodulation - Integrated 32 bit ARM® Cortex®-M0 Processor - Supports I2C interface for field programmability - Programmable current limit - Over-Current and Over-Temperature protection - Active low enable pin for electrical on/off - Pre-defined programmable LED patterns - Dedicated remote temperature sensing - -40ºC to +85ºC ambient operating temperature range - VFQFN 5mm X 5mm, 40 pin package Figure 1.
