TPS2115: Is it possible case that Q1(IN1-OUT switch) and Q2 (IN2-OUT switch) are both on?

K.Yaita

Part Number: TPS2115

Hi Team,

The datasheet shows the following TRUTH TABLE.

Is it possible case that Q1(IN1-OUT switch) and Q2 (IN2-OUT switch) are both on under specific conditions?
If the answer is yes, I would like to know the condition.

Hi Yaita,

The TPS2115 is designed in such a way that only one of the transistors (Q1 or Q2) is on at one time. The device does this to block reverse current and prevent current flow from one supply into the other.

Thanks,
