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.
