Overview
Wireless Power Transmitter for ≤3W Applications P9235A-R Datasheet 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 communication 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 complete 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.
