It won't unless its gate voltage Vgs is >> Pack+ voltage. What drives the gate?but Q3 just won't budge
If Vgs is really 22V then that may exceed the rated maximum for that FET (I haven't checked) but should have been prevented by the 16V zener. Or do you mean Vg? What is the Vs voltage?The Vgs of Q3 is just resting at 22v
My apologies, I meant Vg -> bat-If Vgs is really 22V then that may exceed the rated maximum for that FET (I haven't checked) but should have been prevented by the 16V zener. Or do you mean Vg? What is the Vs voltage?
Is the bq40z80 correctly programmed to handle a 7S pack?
It certainly can be . Glad you've got it sorted.Engineering is hard..
