Tool/software:
Hi,
I am calculating Pullup resistance based on this article but the values don't align well. Can you please check and confirm what I am missing out?
Rpmin = (Vcc-VoL)/IoL = 2.5-0.8/(10uA) = 170kohms
Rpmax = tr/(cb*0.8473) = 1us/(400pF*0.8473) = 3kohms
Vcc = 2.5V is considered since my resistor pullup voltage is 2.5V even though the IC's supply is 3.3V
VoL = 0.8V taken from Pg 6 VIN(0) value
IoL = corresponding Logical “0” Input Current
Cb = 400pF for std mode
tr = 1us based on SMBus Rise Time in Pg6
Thanks
