Other Parts Discussed in Thread: LM5066
Tool/software:
Hello,
I am now building a system to change the power source during operation.
For example: change to another Battery pack if the other is close to empty; replace battery pack while the system is operating for charging or something else.
The structure can be expressed as below
But as I read the LM5066I datasheet, I did not find information about how it handles the reverse current.
if my two battery packs are not balanced then if there are an interval when a battery is switched on and the other is switched off, a reverse current may occur.
I can see that the current sense signal can be up to -0.3V according to datasheet.
But as I understand, a hot swap controller will increase it gate voltage if the output current is below the programmed value.
In case the switching on battery pack has lower voltage than the switching off pack, can the reverse current on switching on battery cause the gate voltage to be saturated and when the other battery is completely removed this saturated gate voltage can cause over current event or something?
I simulated the system on PSPICE for TI and did not see anything dangerous if I switch the two Packs simultaneously, but in the real life does my system lack of some protection solution?
Is OR-ing diode controller needed in this Case?
