Tool/software: TINA-TI or Spice Models
Dear colleagues,
Im develloping an application circuit which the main purpose is to charge a battery (Li-on) from an magnetic source. After, the aim is to put a load that works at 3.5V.
I have designed the circuit using a pspice model, however some of my results are not consistent with the data i should get. The problems i find are
- The Vbat_ok is always off, even the battery its fully charged. I tested in other simulations.
- Is it normal that the 1F capacitor starts charging from 0seconds time?
In the other hand, regarding the Vout, the Vout (PINK) is on from the moment that Vstor =Voc_sample reaches the voltage reference: Vbat_ok_hyst (3,4V set by me). This result is consistent with the literature.
(To simplify the circuit Im using an 1F capacitor instead of a lithium Bat.)
I would like to have your help regarding this issue, I cannot figure out what is missing.
Thank you in advance!
