Are you still using bus isolation modules in automotive projects? [Copy link]

Are you still using bus isolation modules in vehicle-mounted projects? The profits of vehicle-mounted projects are relatively low now, and I feel that I can't afford it....., and I'm afraid that the chip will burn if I use it directly... For example, Zhou Ligong's CTM8251 series, RSM485 series, MRT1040DLT MRT485DLT series. We have been using MRT1040 and MRT485 series before, but the price is relatively high, more expensive than Zhou Ligong's, but one advantage is the low power consumption of the MRT series. The CTM series consumes too much power. The 8251 series is almost 40ma, the MRT1040 is only about 28ma, and the MRT485 is only 12ma. As for the price, I heard that MRT will soon launch low-cost modules, and I am looking forward to it.

I hope some niche brands can develop and the market can have more choices;

It is true. There are two companies on the market now: one is Jinshengyang and the other is Zhou Ligong. Both of them use the same solution, which is an isolated power supply with high power consumption and high heat generation. It is time to change it.
