can touch a grounded surface, a charged machine can touch an IC, or an electrostatic field can induce a voltage across a dielectric sufficient to break it down. The main threat of ESD damage occurs during the assembly and manufacturing of circuits. After assembly and installation, the main pro...
When no transmitter is driven, pull-up resistors set the bus to VCC/2, producing the recessive signal, which represents a logic high. A standby control puts the transceiver into a low-power mode. A low-power receiver remains active during standby mode, monitoring the bus for state changes—...
and electrostatic discharge can cause damage to CAN transceivers by generating large transient voltages. The following electrostatic discharge (ESD) protection, electrical fast transients (EFT) protection, and surge protection specifications are relevant to industrial applications: ...
Warning!Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other components. The circuit board must only be handled at an ESD workstation. If an approved station is not available, some measure of protection can be provided by wearing a grounded antistatic wrist strap. Keep...
If we didn’t have the termination resistors in the middle, the common-mode choke would go second. Figure 4. Example routing. In our example PCB, there is still room for improvement. The TVS diode could be rotated by 180 degrees to reduce the ESD loop area further. The capacitors C5 ...
This prevents transients, ESD and noise from penetrating onto the board and disturbing other devices. Bus termination: Figure 27 shows split termination. This is where the termination is split into two resistors, R5 and R6, with the center or split tap of the termination connected to ground ...
-there is no short circuit between CAN_H and CAN_L wiring -there are not more than two terminating resistors -the nodes do not have faulty transceivers. If the value is higher than 70 S , please make sure that: -there are no open circuits in CAN_H or CAN_L wiring -your bus system...
12.4 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance...
