    1. ISO7637 protection module MRT7637PL data file and package file

      MRT7637PL is a high-voltage protection module dedicated to the ISO7637 standard. Different from the way TVS absorbs peak current, MRT7637PL uses a blocking method to defend against high-voltage pulses. As the name implies, blocking means that when a high-voltage pulse comes, the pulse is directly blocked outside the system, physically blocking the high voltage, thus protecting the subsequent circuits in the system. Its advantages are: it does not absorb high-voltage pulses, so it does not generate heat, and the life of components will not be affected. Since it does not absorb high-voltage pulses, it does not generate large currents, so the fuses in the car will not be blown. The specific parameters of MRT7637PL are as follows: 1. Working voltage: 9-100V 2. The highest withstand voltage is 180V (±2V) 3. Working current <2ma 4. Maximum through current 9.4A 5. Protection voltage 40V (±2V)

    5. CAN isolation module MRT1040DLT data files and package files

      MRT1040DLT is a very good CAN isolation module. This module can directly replace Zhou Ligong\'s CTM8251, CTM1040, and CTM1050 series with PIN to PIN. It has more advantages than Zhou Ligong\'s modules, mainly because its power consumption is about 12ma lower than that of the CTM series modules. MRT1040DLT uses a real isolated power supply inside, not the self-oscillating triode isolated power supply of Zhou Ligong\'s series. It has the advantages of low power consumption and no heat, etc. In addition, MRT1040DLT supports wide voltage input and supports voltage of 3.3V-5.25V, avoiding the trouble of selection.
