Tool/software:
I tried simulating TPS26601 Transient Model in Start Up state. I see difference in behavior of simulation output vs calculated results.
Calculated Values of R1,R2, & R3 for OVP & UVLO fault as per TI Spreadsheet calculator as below,
I used the same recommended values of R1,R2 &R3 in pspice simulation shown below,
As per calculated threshold limits shown in above spreadsheet calculation, Fault is not triggering at 3.4%.
Simulation observation :
UVLO Fault triggering at 44.71V
OVP Fault triggering at 48.8V
Could you please clarify it & pspice model i download is write access denied - it could be problem in getting wrong outputs?
Thanks
