製品概要
概要
The STWBC2HP is a digital controller specifically designed for wireless power transmitter (TX) applications. It is a System-in-Package (SiP) that includes an STM32 microcontroller and an application-specific front-end die.
The STWBC2HP is capable of driving the DC-DC stage and the half- or full-bridge inverter stage of a generic wireless battery charging transmitter (TX). It generates and controls the relevant PWM signals using a PWM machine with a resolution of 1.47 ns. To achieve this, the front-end die includes a 40 MHz PLL and a 17-step DLL.
The STWBC2HP front end can work from any DC voltage in the range of 4.1 V to 24 V and embeds:
- 3x half-bridge drivers capable of driving both the FB inverter or the DC-DC MOSFET
- 2x PWM outputs for external gate drivers
- 2x LED drivers
- 3.6 V/5 V monolithic buck DC-DC to supply the analog portion of the die
- 3.3 V LDO to supply the STM32
- 1.8 V LDO to supply the core
- 6 V or 9 V voltage doubler to supply the gate drivers
- Resonant tank current, voltage, and phase sense circuitry and Q-factor driver
- USB D+/D-, CC1, CC2 external interface pins for USB PD
The STM32 microcontroller features an Arm Cortex™-M0+ CPU with up to 128 KB of flash memory and up to 32 KB of SRAM with parity check, operating at a clock frequency of up to 64 MHz. It also includes a 12-bit, 0.5 μs ADC and provides UART, I2C, SPI, and GPIO interfaces.
The STM32 embedded in the STWBC2HP also provides two 12-bit DACs and a USB Power Delivery controller.
