产品概述

描述

The STWBC2 is a digital controller specifically dedicated to design Qi-certified Wireless Power TX applications. The STWBC2 is an SiP including an STM32™ microcontroller and an application-specific front-end die. Specifically, the STM32™ microcontroller embedded into the STWBC2 is the STM32G071.
The STWBC2 is capable of driving the DC-DC stage and the half- or full-bridge inverter stage of a generic Qi wireless battery charging TX. It generates and controls the relevant PWM signals by means of a PWM machine capable of 1.47 ns resolution. In order to achieve that, the front-end die includes a 40 MHz PLL and a 17-step DLL.
The STWBC2 front-end is capable of working from any DC voltage in the range of
5 V to 24 V and embeds:
The front-end die also includes specific registers and an SPI interface with the STM32, in combination with an output mux for analog signals to the STM32 ADC, and GPIOs for digital signals to the STM32 core.
The STM32 microcontroller embeds an ARM Cortex™-M0+ CPU with up to 128k Flash memory and up to 32k of SRAM with parity check, with a clock frequency up to 64 MHz. It also embeds a 12-bit, 0.5 μs ADC and provides UART, I2C, SPI and GPIOs.
The STM32G071 embedded in the STWBC2 also provides two 12-bit DACs and USB-PD controller.
