Hi,

Need a clarification on Functional Block diagram of TPS7A9001DSKT Device.

In the Block Diagram Input for Op-Amp is showing 0.889xVREF.

Is that Voltage is product of those two or only just VREF..? i can see VREF=0.8V from the electrical characteristics.

Thanks

Hi Rajeshnag,

It's the product of the two which is 0.889 x Vref. This comparator is controlling the PG logic s. As you can see, PG threshold is a percentage of Vref voltage and this is where the 0.889 comes from.
