Description
The CV90331 is a wireless charging transmitter SoC
chip integrated with PD/QC function, which supports
power supply from various adapters such as PD2.0, PPS
(3.0), QC2.0, QC3.0, AFC, SCP, etc., supports WPC
V1.2.4 wireless charging protocol, and CV90331
integrates an enhanced 8bit MCU, 16Kbytes MTP memory
that supports 2000 erasing, 1Kbits Xdata RAM, and 12bits
high-precision analogue-to-digital converter (ADC).
High-speed PWM generator can support multiple outputs,
digital decoding circuit, built-in full-bridge drive and a
high linearity low offset operational amplifier for current
sensing, rich IO interface resources.
The enhanced 51CPU core provides the flexibility of the
system, and high-speed PWM can provide higher
adjustment accuracy, thereby providing more accurate
energy transmission and improving the systematic
efficiency. Each analog module can be closed and enabled
independently to ensure the lowest static power
consumption of the system, which conforms to low power
requirements for European Energy Star（Energy Star? )
The wireless charging transmitter chip provides
complete low voltage reset（UVLO），OVP、OCP、OTP
etc. functions and support FOD.
The CV90331 has QFN48L 5mmX5mm and 6mm x
6mm two types QFN-package, and MOQ are 3Kpcs and
2.5Kpcs respectively. The working temperature is -40oC to
+85oC.
