As a leading manufacturer dedicated to providing a wide variety of products and solutions, ON Semiconductor has designed distinctive solutions to customer system requirements in its key automotive areas to help customers improve automotive energy efficiency, reduce energy consumption, and achieve environmental Continue to develop.
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 higher than the average growth rate of the semiconductor market. In 2010, China alone produced 18.4 million vehicles. These cars have added many new comfort and convenience functions, as well as advanced headlight systems and LED lighting. In addition, due to the impact of hybrid vehicles and future emission regulations, hybrid and pure electric vehicles have begun to be on the development agenda.
ON Semiconductor ’s key automotive applications for the Chinese market include in-vehicle networking (IVN), automotive infotainment systems and automotive LED lighting. Power management and in-vehicle networks achieve fuel economy and emission reduction through engine control, transmission, and hybrid power; power supplies provide power to microcontrollers, infotainment systems, telematics systems, body computers, and gateways; lighting includes external (LED, HID, xenon lamp, advanced headlamp system (AFS)), interior (instrument panel, door, accent lighting). In addition, there are ASICs for power systems to implement engine control, sensors, starting AC motors, and transmission control.
Infotainment system solution
ON Semiconductor's products used in power supplies for infotainment systems are mainly 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 controller / regulator, synchronous / asynchronous operation, high frequency / low quiescent current, battery and post-regulation; power management unit (PMU), with Higher integration and optimized size / performance. These products meet the requirements of next-generation size and energy efficiency.
The use of advanced power management technology can achieve low quiescent current (Iq) power management, sleep wake-up function and high energy efficiency energy saving methods. ON Semiconductor's Iq> 60 μA standard quiescent current LDO NCV42xx provides a second source beyond Infineon's TLE42xx devices; NCV85xx is feature-rich and can replace similar devices from Infineon / STMicroelectronics / National Semiconductor or exclusive supply Device. Very low quiescent current LDO NCV86xx (33 μA <Iq <50 μA) is pin-to-pin compatible with standard quiescent current devices; ultra-low quiescent current LDO NCV87xx (Iq <33 μA) is 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 two types, buck and boost. The former includes voltage regulator NCV8901 / 02 series, high-performance controller NCV8851 and low-cost controllers NCV3020, LV5749NV, etc. The latter includes boost controllers such as high-performance NCV8871 and low-cost NCV3063.
The power management unit NCV8855 has the following characteristics: switching power supply buck controller, 2 A switching power supply buck converter, 2 way LDO controller, 2 A high-side switch, its frequency is up to 600 kHz, providing 170 kHz, 340 kHz options, And ROSC or SYNC options. NCV8612 is a 3-way LDO output, with different voltage / current selection, automatic switching (ASO) function, ultra-low quiescent current (Iq) <50 μA can reduce power dissipation. NCV8881 uses 1.5 A switching power supply voltage regulator control converter, 8.5 V / 40 mA / 5.0 V / 100 mA LDO, with ROSC and SYNC and watchdog function, the frequency is up to 600 kHz.
ON Semiconductor's DSP tuner is a high-performance solution in line with current trends, suitable for high-end digital radios. Its unique continuous modulus algorithm (CMA) technology can greatly reduce multi-channel noise and reduce peripheral components (such as coils, diodes, ceramic filters) by 52. It supports HD broadcast interface, adopts LNA / MIX new design, corresponds to the global frequency band, and the dual-tuner adaptive array antenna (adapTIve-array-antenna, AAA for short) technology is mature.
ON Semiconductor also provides the RTIC (Real-TIme Traffic InformaTIon of China) program, which provides taxi-backed road condition information for the road information feedback system in 22 cities in China, which is then released.
ON Semiconductor's automotive infotainment system power supply solutions can meet both high performance requirements and low-cost solutions, covering most infotainment system power supply applications.

In short, Dashcoin Dash is a variant of the Bitcoin cryptocurrency that runs on the same blockchain network. Dashi, which combines the words "digital" and "cash," has become one of the most widely watched counterfeit coins in recent months. Originally released as "XCoin", it was later changed to "Darkcoin" and later Dash.
Arguably the biggest benefit of Dashi is that its transactions can be sent completely anonymously, just like legal cash payments. This is achieved by using a hybrid protocol that operates a dedicated network of servers called Masternodes. While Bitcoin operates only a single-layer network of miners, Dashcoin uses these master nodes as additional layers to its network, eliminating the need for a trusted third party to authorise a transaction that could compromise the anonymity of any payment.
Another major difference between Dashcoin and Bitcoin is that the former distributes mining rewards between its mining community, participants holding a specified amount of Dash, and the Dash community's long-term development fund.
