Indie Semiconductor unveils automotive wireless power charging system

The company states: “indie Semiconductor has launched an integrated automotive wireless power charging system-on-chip (SoC) that offers the industry’s highest level of integration. The iND87200 simplifies and accelerates the development of cost-effective WPC ‘Qi’-based in-cabin portable device charging designs. In-cabin charging has become a necessity for drivers and passengers who use their smartphone to provide navigation, music, voice connections and other services on-the-move. The global semiconductor-enabled in-car automotive wireless charger market is estimated1 at $1.3B for2022 and is forecasted to grow to $9.5B by 2032, representing a 22% CAGR over this period. The emerging Qi 2.0 standard featuring the Magnetic Power Profile is particularly relevant to automotive designs, offering faster, more reliable charging by automatically aligning smartphones with an inductive charging coil, maintaining the device in position irrespective of vehicle motion. The iND87200 dual-core design combines an Arm Cortex M4F processor with 2MB of embedded Flash and 256kB of SRAM with a dedicated Arm Cortex M0 processor for the WPC stack. This approach frees SoC compute resources to execute user-specific software without timing and interrupt constraints related to the WPC stack. Further, indie’s wireless charging solution integrates all of the necessary power management, DC-DC converter, signal conditioning, WPC inverter drivers, and power FETs as well as LED and fan drivers. A wide range of serial interfaces such as CAN 2.0B, LIN, I2C, and UARTs provide multiple connectivity options to the vehicle and other peripherals.”
