Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[Details]
I. Introduction
Since RS232 has a short communication distance (only 15 meters according to EAT/TAI-232 standard), and can only perform point-to-point communication, it cannot directly f...[Details]
1. System Structure
This system is a simulation system of indoor air-conditioning temperature/humidity control system. The data acquisition and control center collects temperature/humidity...[Details]
1. Introduction
Testing the temperature of steel billets before rolling is an important measure to ensure the quality of steel. Traditional manual testing is difficult to ensure product qu...[Details]
Digital array radar (DAR) uses digital beam forming (DBF) in both receiving and transmitting modes to achieve flexible distribution and reception of RF signal power in the airspace, obtain excellent t...[Details]
TC9012F is a universal CMOS large-scale integrated circuit for infrared remote control signal transmission, suitable for remote control of TV, VTR, laser player and other equipment. In the market, ...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
The TPS92210 is a single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimmable solution not only regulates the LED current, but also achieves a power factor close to 1. The...[Details]
Against the backdrop of global warming, energy conservation and emission reduction have become a global hotspot and focus, which has also sounded the clarion call for the take-off of the LED lighti...[Details]
Car lights, whether headlights, fog lights or tail lights, play an important role in driving safety. However, the material of the car lights determines that the probability of damage in a collision...[Details]
Multimedia processors are often the most power-hungry devices in portable electronic devices. Common ways to reduce CPU power requirements are to reduce clock frequency or operating voltage, but th...[Details]
