• Launches World’s First Hot Plug Safe Design in Support of Global Telematics Applications
• Highly Integrated Single Chip Solution Dramatically Reduces Customers’ Time to Market and Bill of Materials

ALISO VIEJO, Calif. — (BUSINESS WIRE) — March 11, 2021 — indie Semiconductor, an Autotech solutions innovator which is currently in the process of becoming a public company through a planned merger with Thunder Bridge Acquisition II, Ltd. (Nasdaq: THBR), a special purpose acquisition company, today launched a new on-board diagnostics (OBD) device, the OnBrD™. The OnBrD™ is a complete hardware and software solution for high-performance OBD-II applications including vehicle tracking, geofencing, connectivity, real-time automotive diagnostics and black box event data recorders. Specifically, indie’s compliant line drivers and hardware controllers make the OnBrD™ a hot plug safe device, while its distinctive, highly integrated, single layer architecture supports both new and existing system platforms.

OBD-II solutions monitor a car's computer system and report trouble codes. The electronic control unit then uses a microprocessor to read inputs from various engine sensors in real time. When a reading is outside of the expected values, the system logs a diagnostic trouble code (DTC), which is read through the OBD port. Remote diagnostics are extremely valuable tools in preventive maintenance and scheduling vehicle service cycles, reducing downtimes and the risk of breakdowns.

“Telematics, remote diagnostics and black box event data recorders are rapidly proliferating across a wide range of automotive applications including fleet management of passenger and commercial vehicles,” said Paul Hollingworth, indie’s executive vice president of sales and marketing. “Leveraging our decade-plus of Autotech system-level expertise, indie has developed a truly breakthrough single chip OBD-II interface solution to accelerate Tier 1 time to market, while substantially reducing their bill of materials. At a higher level, today’s announcement reflects how indie is rearchitecting the vehicle of tomorrow today, addressing the market’s need for innovative platforms that enhance safety, deliver real-time diagnostics and support new and emerging high growth applications.”

According to Technavio, the automotive on-board diagnostics market is expected to grow by $35 billion from 2020 to 2024 driven by the growing focus on remote monitoring and system management. Factors such as the shift in focus from OBD hardware and OBD software, and the integration of OBD with telematics will have a significant impact on the growth of the automotive OBD market value during the forecast period.

About OnBrD™

The OnBrD™ is a complete hardware and software solution for high-performance OBD-II applications. It includes the full stack from PHY through to application layer in a single, easy-to-drop-in package for both new and existing designs.

This highly integrated platform is designed to direct wire to the J1962 interface. An innovative crossbar function inside the design enables the multiplexing of any protocol on any connector pin, providing software configurable support for government mandated pinouts, as well as proprietary, per vehicle/machine interfaces. All pins are capable of being driven by the CPU or commonly, through the built-in hardware protocol accelerator.

OnBrD™ integrates an application processor, reducing bill of material costs by enabling the user application to run on the single-chip solution. Provided reference software includes support for a world-class turnkey J1979 stack supporting vehicle compatibility, ignition algorithms and safety functions, including crash detection. The firmware also provides support for common peripherals including radio/location/MEMS sensors and includes integrated RTOS, filesystem and logging infrastructure. Peripherals available to the CPU include GPIO, UART, RTC, PWM, I2C and SPI.

The OnBrD™ leverages indie’s field-proven, mixed-signal automotive technology and has been production-qualified to the AEC-Q100 Grade 1 standard. The iND83405 is available now in production quantities. References designs include J1979, system-on-module, vehicle simulator and cable accessory based products.
