WPC Qi Wireless Power Transmitter Datasheet
Description
Features
The CV90328B is a system-on-chip device for magnetic
induction wireless power transmitter application,
supporting WPC specifications. The SoC is comprised of a
MCU, Three half-bridge power stage drivers,12bits ADCs,
high-speed PWM, a low offset Operational amplifiers ,
Demodulation unit, and 2000 times MTP memory.The
device support I2C, Uart, SPI interface.The transmitter
includes an industry-leading 32-bit ARM® Cortex®-M0
processor offering a high level of programmability while
consuming extremely low standby power and meeting the
ENERGY STAR® requirements. In addition, the
microcontroller empowers the user to customize features
such as LED patterns, buzzer, and FOD threshold settings.
The enhanced MCU and high-speed PWM can offer high
High-precision power delivery, each analog part can be
disable/enable, so chip consumes extremely low standby
power and meet the Energy Star® requirements.
The transmitter includes input under-voltage, input over-
voltage, output short circuit, and over-temperature protection.
The CV90328B is available in a Pb-free, 7x7 mm,
60pins-QFN package, and it is rated over the
industrial temperature range of -40ºC to +85ºC
