Automotive market environment and its application requirements

From the perspective of the automotive market environment, the automotive application semiconductor market is huge, and the growth rate is even higher than the average growth rate of the semiconductor market. In 2010 alone, China produced 18.4 million vehicles. These cars have added many new comfort and convenience features, as well as advanced headlamp systems and LED lighting; in addition, due to the impact of hybrid vehicles and future emission regulations, hybrid and pure electric vehicles are on the rise.

ON Semiconductor's key automotive applications for the Chinese market include the automotive network (IVN), automotive infotainment systems and automotive LED lighting. Power management and in-vehicle networking for fuel economy and reduced emissions through engine control, gearbox, and hybrid power; power supplies for microcontrollers, infotainment systems, telematics, body computers, and gateways; lighting includes external (LED, HID, Xenon lights, Advanced Headlight System (AFS), internal (dashboard, door, accent lighting). There are also ASICs for powertrains for engine control, sensors, AC motors, and gearbox control.

Infotainment system solution

ON Semiconductor's products for infotainment systems include linear regulators for battery and post regulation, as well as standard/low quiescent current, high power supply rejection ratio (PSRR) / ultra-low quiescent current, tracker and current Sensing; switching power supply (SMPS) for buck and boost controllers/regulators, synchronous/non-synchronous operation, high/low quiescent current, battery and post regulation; Power Management Unit (PMU) with Higher integration and optimized size/performance. These products meet the next generation size and energy efficiency requirements.

Advanced power management techniques enable low quiescent current (Iq) power management, sleep wake-up, and energy-efficient power-saving methods. ON Semiconductor's Iq > 60 μA Standard Quiescent Current LDO NCV42xx offers a second source of supply beyond the Infineon TLE42xx device; the NCV85xx is a feature-rich alternative to Infineon/STMicroelectronics/National Semiconductor or similar offerings Device. Very Low Quiescent Current LDO NCV86xx (33 μA < Iq < 50 μA) is pin-for-pin compatible with standard quiescent current devices; ultra-low quiescent current LDO NCV87xx (Iq < 33 μA) and very low quiescent current device pin-to-pin Compatible, can achieve the purpose of energy saving.

Switching power supplies for infotainment system power supplies are available in both buck and boost modes. The former includes the regulator NCV8901/02 series, high-performance controller NCV8851 and low-cost controller NCV3020, LV5749NV and so on. The latter includes high-performance NCV8871 and low-cost NCV3063 boost controllers.

The power management unit NCV8855 has the following features: switching power supply buck controller, 2 A switching power supply buck converter, 2 LDO controllers, 2 A high side switch, frequency up to 600 kHz, 170 kHz, 340 kHz selection, And ROSC or SYNC selection. The NCV8612 is a 3-way LDO output with different voltage/current selection, automatic switching (ASO) functions, and ultra-low quiescent current (Iq) < 50 μA to reduce power dissipation. The NCV8881 features a 1.5 A switching power supply regulated converter, 8.5 V/40 mA/5.0 V/100 mA LDO, ROSC and SYNC and watchdog functions up to 600 kHz.

ON Semiconductor's DSP tuner is a high-performance solution that meets current trends and is suitable for mid- to high-end digital radios. Its unique continuous modulus algorithm (CMA) technology can significantly reduce multi-channel noise and reduce the number of peripheral components (such as coils, diodes, ceramic filters) up to 52. It supports HD broadcast interface, adopts LNA/MIX new design, corresponding to global frequency band, dual tuner adaptive array antenna (adaptive-array-antenna (AAA) technology has matured.

ON Semiconductor also offers the RT-R (Real-time Traffic Information of China) program, which provides road information for taxi feedback in road information feedback systems in 22 cities in China, and then publishes it.

ON Semiconductor's automotive infotainment power solutions range from high performance to low cost solutions for most infotainment systems.
