The iND87200 from indie Semiconductor is an Automotive Qualified In-Cabin Wireless Charging IC that complies with WPC Qi 1.3 and other proprietary specifications. It delivers an output power of up to 15 W across the entire operating battery voltage range. This charging IC consists of a 32-bit ARM Cortex Core that integrates ARM Cortex M4F processor, 2048 KB eFlash, and 256 KB RAM, WPC transmitter, ADC, multiplexers, temperature sensors, communication interfaces, and power management unit (PMU). It supports the emerging maximum power point (MPP) wireless charging feature and integrates an advanced power sensing circuitry that monitors system impedance and phase in real-time. This AEC-Q100 Grade 2-qualified charging IC enables support of a wide range of AM filter topologies with a unique amplitude shift keying (ASK) demodulation engine for robust operation over different filtering and coil matching combinations. It uses the internal PMU to connect directly to an automotive power bus.
This wireless charging IC includes a wide range of serial interfaces such as CAN 2.0B, LIN, I2C, and UART, supporting multiple connectivity options to the vehicle and other peripherals. It is also provided with development kits to accelerate the design and production process, along with an interactive GUI to enable real-time monitoring of relevant system information. This IC is available in a surface-mount package that measures 12 x 12 mm and is ideal for wireless charging in executive seats in vehicles, console, driver, passenger, and rear passenger hubs, and other in-cabin wireless charging applications.
