Hi,

i'm currently prototyping this circuit and it's not quiet working as it should

when i check OUTA & OUTA individually with it's own pull up everything works

but i once tried to replicate the case where i OR the two outputs together using a single resistor it does not work and the voltage stays low at around 2V

Can someone kindly help please

Hi Jonathan,

Can you please let me know what is your VDD and Vmon voltage ?

Thanks,

Sila

Hi Sila,

if VDD is max voltage to be seen then it's 15.5V

and i want OVP=15.5V ,UVP=13V,voltage divider current to be 10uA,

can you run me through the calculation step by step to get the correct resistor values

Hi Jonathan,

Please check the "8.2.2 Detailed Design Procedure" section of the datasheet. You can use Equation 1 through Equation 4 to calculate the resistor divider values and target threshold voltage.

Did you use the above resistor values to test your circuit? I'm trying to understand your VMon values and resistor divider that yields the voltage stays low at around 2V. Could you please clarify more so I can better assist you with your inquiry?

Thanks,

Sila
