PCA9518: Equation (5) of SLVA689

Hi support team.

www.ti.com/.../slva689.pdf


Is it "t1 - t2"?

t1 = 1.2040 * Rp * Cb
t2 = 0.3567 * RP * Cb

t1 > t2

Regards,

    Hey Dice,

    I walked through the equation and can confirm your t1 and t2 values are correct so t1>t2.

    I'll go ahead and make the change to the app note to be t1-t2.

    Thanks for bringing this to our attention.
