Tool/software:
Hi Expert,
Good day!
This is about the current regulator circuit. I wanted to use the current sensing IC INA169. I want to be able to sense current from 0-1A. The image below shows the schematic and simulation graph. Using the Spice model available. Here is the result.
The red line in the graph is sensing current. The green line is the voltage on the output (Pin 1). On the X axis is voltage from voltage source V1. My question is if the spike on the output at voltage V1 = (cca) 3,2V is Spice model error or if it is correct. Differential input voltage V-shunt is around 50mV at the spike.
If it is not a spice error, would you recommend another current sensing IC that is sufficient for this application The voltage supply for this application is 30V and the output current is 0 to 1A.
Thank you in advance for your support.
Best regards,
Jonathan
