Other Parts Discussed in Thread: TINA-TI
Tool/software:
Hi,
I'm currently simulating the INA302A3 and I'm having issue understand if the model has an issue or if my simulation settings are causing this issue. I have connected the LATCH pins to Vs to get the latching functionality. The two ALERT pins latches immediately to 0 like if there was an overcurrent even if there is no current. I verified the voltage on the latch pins and they are at the correct level. The circuit works as expected if I remove the latching mode and tie LATCH pins to GND. I'm wondering if there is an issue with the model of the INA302A3 or if I'm missing a circuitry to make this work properly. The datasheet seems to indicate we can tie the LATCH pins to high. I've attached my TINA-TI file and the schematic. I tried this circuit in LTSpice also and got the same behavior.
INA302A3.TSC
