Can bus short to ground
WebJan 14, 2024 · 1. 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 ...

The most common failures are poor connections, opens, short to power, and short to ground. A module could also fail and bring down the whole CAN bus by shorting it to ground or power. If you’ve lost communication to only one module, it could be the module, a poor connection, wiring …
WebWaveform notes. These known good waveforms have the following characteristics: The CAN-L and CAN-H waveforms mirror each other about 2.5 V and have a 1 V peak to peak amplitude. The CAN-L waveform switches from 2.5 V down to 1.5 V and the CAN-H waveform switches from 2.5 V up to 3.5 V. The low and high voltages and transitions … Web\$\begingroup\$ Short answer is yes. Unless you have complete optical or magnetic isolation, you ALWAYS need common ground for basically any circuit. ...
WebCAN controllers will tolerate a short circuit of one of the two lines to ground because of the characteristics of the differential bus.

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).
