I am using 2 TLV6710 ICs to provide undervoltage disconnect for a Battery operated Bipolar 6V supply. In my (LTSpice) simulation the TLV6710 monitoring the positive rail works perfectly.
I plan to use the TLV6710 that monitors the Negative Rail by connecting its VDD pin to LTSpice GND and its "GND" pin to Negative 6V. In the actual circuit, the TLV6710 should not be able to tell the difference between the two connection methods, but the spice model does not work when powered that way. It seems that the model may have actually referenced Spice GND instead of its own "GND" pin. The voltages from the voltage divider to the input pins are correct when referenced to the "GND" pin, but the outputs are stuck firmly to LTSpice GND.
I am not savvy enough to figure out why the model isn't working. I'm hoping you can help.
