TechInsights Teardown: LG ADAS front camera

Late last year, LG unveiled its advanced driver assistance systems (ADAS) front camera for use in Mercedes-Benz C-class vehicles.

The front camera acts as the eye of the vehicles to support safety features inside the car. These functions include automatic emergency braking, land departure warning, lane keeping assist, traffic sign recognition, automatic high beam and adaptive cruise control.

ADAS has become a huge part of the future of vehicles with numerous automotive OEMs making a major push into the technology to not just make vehicles safer, but also to differentiate between other vehicle models.

The LG ADAS front camera features SDRAM and serial NOR flash memory from Micron Technology as well as image sensors from Onsemi.

The following is a partial deep dive into the LG ADAS front camera from TechInsights.

Main board

The main board includes the NOR serial flash and the SDRAM memory from Micron Technology as well as other discrete and power management ICs. Specifically, the board includes:

• Renesas’ R-car V3H system on chip
• NXP Semiconductors’ dual supply translating transceiver and flexray node transceiver
• Analog Devices’ step-down DC-DC converter
• Diodes Inc.’s Schottky diode and power MOSFET
• Texas Instruments’ power switch and two-bit bidirectional voltage-level transistor
• Nexperia’s single two-input AND gate
• Onsemi’s dual differential comparator

Front camera subsystem

The front camera obviously needs a camera to operate, and the subsystem includes many electronic components such as:

• A 1.2 amp/1.2-volt LDO regulator from Onsemi
• A 3.1-megapixel BSI CMOS image sensor from Onsemi
• Serial EEPROM memory from Onsemi
