LM66100: The circuit structure has a 6mA pour current.

Arabella Zhang
Intellectual 2880 points
Part Number: LM66100

1.Have R&D engineers help to see why this circuit structure has a 6mA pour current (The electrical circuit diagrams are attached)？


2.There is a question about this circuit: If it happens that two LM66100 VIN's are equal in size, would it be possible that both LM66100 would not have output? This means that the voltage difference between the int+ and int- is small enough.

    Hi Arabella,

    1. It could be that both LM66100s are ON, which is causing cross conduction from one battery to the other. What do the ST pins show when they see this 6mA current from one device to the other?

    2. If both LM66100 inputs are similar in voltage, both devices would be ON. However, if both LM66100 inputs are similar in voltage and both devices were previously disabled for the immediate time before that, it's possible that they could both get stuck in OFF state.

    Thanks,

    Patrick
