Indie Semiconductor has introduced a highly integrated automotive wireless power charging system-on-chip (SoC) for Qi-based automotive in-cabin portable device charging. The iND87200 wireless charging SoC is compliant with the Wireless Power Consortium (WPC) Qi 1.3 standard and supports the emerging Qi 2.0 for improved “on-the-move” charging. It is qualified to AEC-Q100 Grade 2.
The emerging Qi 2.0 standard features the Magnetic Power Profile (MPP), which offers faster and more reliable charging by automatically aligning smartphones with an inductive charging coil, said the company.

The iND87200 features an integrated boost converter that can deliver up to 15 W of power across the entire VBAT operating range. It also integrates advanced power sensing circuitry that monitors system impedance and phase in real-time, which allows system designers to optimize tuning and algorithms, enabling intelligent features such as adaptive foreign object detection, according to indie.
The high levels of semiconductor and software integration reduce the bill of materials by almost half, compared to discrete solutions, while reducing system complexity and improving overall reliability, said the company.
The iND87200 dual-core design features an Arm Cortex M4F processor with 2 MB of embedded Flash and 256 kB 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,” said the company.
The wireless charging solution also integrates all necessary power management, DC/DC converter, signal conditioning, WPC inverter drivers and power FETs as well as LED and fan drivers. It also offers a range of serial interfaces, including CAN 2.0B, LIN, I2C and UARTs for multiple connectivity options to the vehicle and other peripherals.
The iND87200 is sampling to customers. Advanced application-oriented reference designs also are available.
