Team-
The SPICE model for the TLV7031 contains various references to simulation ground ("0") within it.
This prevents the model from simulating properly when V- is biased elsewhere from "0" (see example below).
For instance, here are just a few lines within the model that reference simulator ground:
V_V1 N332115 0 10m
I_I1 V+ 0 DC 315n
R_R1 0 VOUT 1k TC=0,0
Below is a circuit for an ultra-low power ideal-diode that is capable of operate over an arbitrary voltage range, not limited to 6.5V.
T2 provides the ideal diode function and T1 is a cascode transistor that protects the input of the TLV703x. V1 represents a negative voltage regulator operating from the common-output of the OR'ing network.
In order to get this to work, I had to place simulator ground at TLV7031:V- as shown. Very strange results occur if the circuit is grounded in the proper location "REAL_GND".
I have included the TINA simulation if you would like to play with this.
Thanks, Best, -Steve
