We use LM26-CIM5-TPA in our design and we must have a time constant at the OS_lowactive pin, as this signal is used diode ored for several functions.
We pull up this output by 100k ohms to 4.2V, capacitve load should/must be 33nF.
That means the LM26 must sink the load of the 33nF directly, when going low active. I found on LM26lv, that this product can source 1.6mA@3.3V. That is enough for the application.
The only question is: can my device lm26-TPA be destroyed because of (Ic=C*dU/dt) ? I just can find on the datasheet a current limit of 5mA into any pin.
But if the internal FET sinks some mA in any case, that would be no problem, as the low active state only has to sink this current dynamically and not in DC operation.
