TPS2410 - Resistor value calculation for OV, UV pins.

Other Parts Discussed in Thread: TPS2410

In TPS2410 datasheet, Figure 15, can any body provide formula for calculating RA, RB and RC for UV and OV pins?

    Hi Praveen,

    Welcome to the E2E community. First of all, thank you for choosing and considering one of our parts. The equation for the three resistor divider in Figure 15 of the DS is:

    VUV = 0.6*(Ra + Rb + Rc) / (Rb + Rc)


    VOV = 0.6*(Ra + Rb + Rc) / (Rc)

    Where Vuv is the under voltage threshold and Vov is the over voltage threshold. The 0.6 value came from the electrical characteristics of the datasheet (look below).  I would set the value of Ra to 100kohms, and solve for the rest. I hope this helps.

    Best Regards,
