TCAN1043HG-Q1: 48V system request

Part Number: TCAN1043HG-Q1

Tool/software:

Hi expert,

My customer (Enpower) is looking for 48V CAN devices, and I have promoted TCAN1043HG-Q1 to them. But they think the 70V Absolute Maximum Voltage of TCAN1043HG-Q1 is too low for 48 V battery. The maximum transient voltage is about 100V in customer's 48V system. Do you think TCAN1043HG-Q1 can meet this request or do we have more suitable devices? Thanks.

Best Regards,

Ryker

    Hi Ryker,

    TCAN1043HG is the correct device to recommend for 48V systems. Currently 70V fault protection is the highest we offer. 

    TCAN1043HG can handle 100V transients if they strictly follow ISO 7637-2. However, this is a very specific test, and I would recommend the customer validate this with their particular system. I would presume that this device will work with their 100V transient, but that is just my speculation. 

    Let me know if that answers the customer's question,
