In many industrial and automotive applications, protecting interface transceivers from various electrical overstress events is a major concern. Transient Voltage Suppressor (TVS) diodes are commonly used for this purpose as they can clamp voltage spikes by creating a low-impedance current path. The electrical characteristics of TVS diodes are determined by several process factors. These parameters … Read more
In today’s fiercely competitive true wireless headphone market, semi-in-ear headphones have finally ushered in their noise-canceling revolution. While various manufacturers are still battling over parameters in the in-ear noise-canceling domain, the Edifier Lolli ANC has entered the battlefield with its stylish design and ‘semi-in-ear active noise cancellation’ technology, elevating the competition to a new dimension. … Read more
During the development phase of CAN chips, various issues related to communication error management need to be validated. The ISO-16845 international standard specifies comprehensive testing standards, such as error frame detection, transmission frame-related detection, and error management logic validation. This article mainly shares effective and convenient methods to complete the testing. Traditionally, to simulate CRC … Read more
In-vehicle network communication refers to the process of data transmission and communication between various electronic control units (ECUs) within a vehicle. Modern vehicles contain multiple ECUs, each responsible for specific functions, such as vehicle control (VCU), engine control (EMS), braking system (ESC), steering system (EPS), driver assistance systems, body control systems, air conditioning systems, and … Read more
