TLV3202: Equation (4)

Ryo Akashi

Part Number: TLV3202

Hello experts,

I have question about equation (4) in datasheet P14.
"Vin1 = R1 x Vref / R2 x Vref" is correct equation? It should be "Vin1 = R1 x Vref / R2 + Vref "?

Thanks and best regards,

Hi Ryo,

I agree with you."Vref / R2" is the current that must flow through "R1", "R1 x Vref / R2" is the voltage drop across "R1" and this voltage drop plus "Vref" gives the necessary "Vin1" to make the comparator to switch.

Seems to be a typo.

Hi Ryo,

Thanks for bringing this up. Yes this is a typo and we are aware of this, we are looking to update this in the next datasheet revision. Should be “… + VREF” as you mentioned
