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.

Runshi Technology recently launched the RS3011-Q1 voltage following LDO, which redefines the power supply standards for automotive off board sensors with groundbreaking technical parameters. This product, crafted with automotive grade technology, achieves an ultra wide input voltage range of -40V to 45V. Its output voltage accurately tracks the reference input (VOUT=VREF) with a maximum tracking error of only 4mV, providing unprecedented power supply reliability guarantee for automotive electronic systems
