The performance parameters of CAN isolators are a key indicator to evaluate their suitability and performance. Here are some common CAN isolator performance parameters:
1) Isolation voltage: The isolation voltage that the isolator can withstand, usually in volts (V). This parameter determines the ability of the isolator to isolate between systems with different potentials, thus protecting the system from electrical noise and interference.
2) Transfer Rate: The maximum data transfer rate supported by a CAN isolator, usually measured in bits per second (bps) or megabits per second (Mbps). This parameter determines the performance of the isolator in a high-speed communication environment.
3) Delay time: The transmission delay of data as it passes through the isolator, usually measured in nanoseconds (ns) or microseconds (s). Latency is important for systems with high real-time requirements.
4) Common mode transient immunity: The ability of the isolator to resist common mode transient interference. This parameter reflects the stability and reliability of the isolator in harsh electromagnetic environments.
5) Insulation resistance: The insulation resistance value of the isolator between the input and output, usually in megaohms (m). This parameter determines the performance of the isolator in terms of galvanic isolation.
6) Operating temperature range: The temperature range within which the isolator works normally. This parameter is important for systems operating at different ambient temperatures.
7) Power supply requirements: the power supply voltage, current and stability requirements required for the isolator. This parameter is crucial in selecting the right power supply** device.
8) Package and interface type: The package form and interface type of the isolator, such as DIP, SIP, SMD, etc., and the interface type such as DB9, M12, etc. These parameters determine how the isolator is installed and connected in a practical application.
