TCAN2451-Q1: Lifetime Switching Cycles

Part Number: TCAN2451-Q1

Hello everyone,
I have a question regarding the behavior of the module with a high number of switching cycles.
Do you see any risk of the component lifetime by having about 300.000 power supply (12 V) on/off cycles?

Best regards

    Hi Dennis,

    Thanks for reaching out on E2E. 

    Nope, no risk at all. Cycling the 12V supply on the VSUP pin will not degrade the IC's lifetime performance as it is well within the devices absolute maximum voltage rating. So consistent cycling will not be a problem. 

    Best,

    Ethan
