Can bus short to ground
WebAug 18, 2024 · A ground fault is a type of fault in which the unintentional pathway of the straying electrical current flows directly to the earth (to the ground). Here, too, the circuit is "short," in that it has bypassed the circuit wiring, so a ground fault can technically be defined as one type of short circuit. And, as with any short circuit, the ...

WebA split bus termination, consisting of two identical resistors (60 Ohm) and one capacitor (typically 4.7 nF), acts like a low-pass filter; high-frequency signals are shunted to ground without affecting the d.c. voltage relationships. Measurements have shown that this can improve noise immunity and reduce emissions. WebOct 3, 2024 · There must be a ground plane right underneath whatever signal you’re clamping to ground to keep the path of least impedance as short as possible. Your TVS …

The most common CAN-Bus issue is too much or too little termination resistance. In a low speed CAN each device should have a 120 Ohm resistor. In a high speed CAN-Bus (>100Kbit, used in automotive) only each end of the main loop should have a 120 Ohm resistor. Measure with a multi-meter the resistance …
WebAug 11, 2024 · Hence the capacitor C1: Provides the shortest path from digital ground to earth at very high frequencies (i.e. noise) by its nature. C1 is open at low frequencies or DC, but you want a path from your digital ground to the earth. Hence the resistor R3. 1M/1n pair is widely used for that purpose (e.g. ethernet chassis to earth). WebTo test for defective transceivers, please proceed as follows: Switch on all supply voltages. Terminate all network communication. Measure the DC voltage between CAN_H and GND (measuring point (2), see circuit …

Those are worst case short circuit currents. If something breaks and the CANL pin gets directly connected to 12V supply voltage, maximum of 200mA can flow when it tries to drive it low. And the other case, if CANH gets connected to -7V, max 200mA can flow. Wires must handle at least this current. Surely most small signal relays can switch 1 ... reacher in prime
