TCAN334: TCAN334DR protection

Part Number: TCAN334
Other Parts Discussed in Thread: SN65HVD234

Hai,

In our current design we are using TCAN334DR part and for this design we are going to conduct ARAI test ,

As a part of test this particular IC output pins CAN H and CAN L will get shorted to VCC_12V/VCC_24V for 1 min for which IC should get protected from this test,

Please confirm whether  CAN H and CAN L can sustain this voltage if not what sort of protection to be provided for IC to get pass this test

Regards

Jyothi

    Unfortunately, this device could be damaged by any voltages on the CAN pins exceeding +/- 14 V, as indicated by the "absolute maximum" ratings table in the datasheet. To pass this test, you could design a circuit which disconnects the transceiver from the bus when high voltages are detected or you could switch to a transceiver with a wider absolute maximum voltage rating such as SN65HVD234.
