TINA/Spice/LM5104: LM5104 TINA model, doesn't work?

Part Number: LM5104
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Hello everyone,

I am trying to control the LM5104 with an external voltage (pulse generator) in the pin IN to control 2 gating signals. According to what I understood, when there is high level in IN pin you get high level in OH and low in LO and vice versa.

The left part of the circuit is the one included in the datasheet. The right part is my circuit, where I want to control the voltage coming to the diode, either -50V or 1V. In this simulation in TINA I always get -50V in the diode. The idea is to connect a pulse generator in IN pin, so the diode will be directly polarized only in certain cases. -50V is in the pin I_PIN_EN_OL. Best regards,
