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: 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. https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2021-10-16 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2021-10-21 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2021-12-06 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2023-02-12 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2024-04-29 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2024-10-30 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2024-11-16 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2025-02-16 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2025-03-06 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2025-04-03 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2025-04-12 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2025-06-30 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2025-07-10 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2025-12-02 https://elecena.pl/product/19644479/stwbc2-hp-digital-controller-for-wireless-battery-charger-transmitters 2026-03-15
