TI,
I am having issues with the TI Models for the INA139 and INA169 Current Sense Monitors. Simulation files for each type are attached.
Neither model will work correctly in a bipolar configuration to measure negative current and also the INA139 will not converge properly in this configuration. I would expect the output of either model provided to be 1V no matter which direction the current is flowing, per the datasheet.
Can you assist with this? Much appreciated.
