Other Parts Discussed in Thread: LM2904B
I have a question to the LM2904B operational amplifier, which we have in our motor current ripple module.
The OP will be supplied by charge pump voltage and works fine, if we have it in stable mode.
To reduce the current flow out of the charge pump we want to disable this supply if no motor is active.
Can there be a damage of the LM2904B, if the supply is disabled, but there will be some voltage with maximum Vbat on the input lines?
Many Thanks
Josef
