Tool/software: TINA-TI or Spice Models
Hi,
I am using TL331-EP for my design. I have downloaded Pspice model from TI Web.I am using TL331-EP for Comparator design with hysteresis.
My Comparator design is explained as below
- For an input of 0V-4.5V it should provide high output.
- For an input of 10.5V-49V it should provide low output.
- Range between 4.5V-10.5V is covered by hysteresis.
My application requires supply Voltage of 3.3V to the TL331-EP.The simulation results are not correct with 3.3V power supply to TL331.
But if i change supply voltage to TL331 to 5V then it works satisfactorily.
As per the TL331 supply voltage range (2V-36V)it should work with 3.3V as well, so why i am facing the issue.
I am attaching my deisgn as well.
Thanks ,
Rahul Wagh
