P9235A-R集成电路（IC）的电源管理-专用规格书PDF中文资料

描述 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.
