LM317: Can't simulate in TINA-TI for battery constant current charging

Part Number: LM317

Can' charge a battery in TINA when configured as constant charging mode.

  • Hi Lanhua,

    The TINA simulation you have provided uses a fixed voltage source as the "battery".  Yes, I realize that in TINA it is labeled as a "battery" however you can think of this Spice element as a fully charged battery, with nearly zero source impedance, that is feeding voltage back into the linear regulator.  What you need instead is a circuit that models or approximates your real world battery.  There are many battery chemistries available so you will need to research the right model for your particular battery chemistry.

    Thanks,
