Hi

I looked through reference design of 2x60W rev3 (CCG3PA + MPQ4230). I'm a little confused by Vconn control circuit which I attach here. What's the resistor circuit of R16/R59 for ? Thanks.

Hi Grace,

R16/R59 is for Vgs(th) enable and disable threshold divider. This two resistor is to make sure disable voltage lower than 1.5V and enable voltage higher than 2.5V.

Best Regards,

Lisa
