Recently, International Data Corporation (IDC) released the latest "China POL Market Tracking Report, 2024H2". The report shows that Huawei ranks first in the market share of Passive Optical LAN (POL) in China in 2024, which is also the sixth consecutive year that Huawei has been ranked first in this market.

The new gate driver integrated circuit integrates bootstrap diodes and resistors, which helps simplify the high-speed design of brushless motors, power tools, and DC-DC converters

With the popularization of 800V high-voltage platforms, the risk of overvoltage in vehicle electronic systems has sharply increased. The traditional voltage detection IC faces the technical paradox of "increasing speed inevitably increases power consumption" - for every 1 μ s increase in response speed, power consumption often increases by more than 5 μ A. ABLIC (a subsidiary of Meibeiya Sanmei) has made a breakthrough by launching the S-19116 series voltage detector IC, which achieves a revolutionary upgrade in safety and energy efficiency with the industry’s fastest overvoltage response of 6.8 μ s and ultra-low operating current of 2.0 μ A. It builds a safety defense line for core systems such as BMS and OBC.

Thick film resistors have become key components in automotive electronic systems due to their high power density, high temperature resistance, and resistance to pulse impact. Under the trend of electrification and intelligence, its application scenarios have extended from traditional ECU control units to high-voltage battery management systems (BMS). This article focuses on two core scenarios: CAN bus terminal matching and BMS current detection. Combining vehicle certification with real cases, it analyzes the selection strategy of thick film resistors and the original factory solutions.
