Hi,
I am planning to use the LM74930-Q1 as the surge protection IC for a battery protection circuit.
But since I'm trying to protect the battery in this case. I need to supply the circuit from my battery, which will be in the output, to be protected. Because if I try to supply the circuit from the input (where would the surges and overcurrents come from) circuit would only work when there is a charger connected to the terminals, and would not work when the battery is supposed to supply a load.
So long story short, would LM74930-Q1 work if I supply it from the output if:
-I use the IC in overvoltage clamp mode, so there is always voltage in the output. (Other than reverse polarity event)
-I pull the MODE pin to GND to allow current in both directions.
Would current protections cause any problems when the battery is discharging current into the load? (There is reverse current in the bus.) If so, can I disable the current protections in some way? I already have overcurrent protections on the battery side. I just need input reverse polarity, and surge clamp functionality from the IC.
