Hi team,

by definition , BT pin will pull low under type-3 or 4,

so customer wants to know if below condition (2-3 class cycle) would also pull low BT?

    Hi Fred,

    Thanks for reaching out. 

    If the PSE is BT standard, the 1st classification pulse length will be longer than AT/AF. Then the BT pin should be L no matter the PD class. Let me know if BT pin output is not as expected. 

    Best regards,
