yh op-amp could be used, but this circuit has to be as small as possible.
ideal solution would be using lithium protection ICs but again size, and i cant be doing with hand soldering more surface mount stuff (plus deadline is getting closer)
anyway, ill stick in a pot and tune it. just have to hope the default for EN between 0.4 and 1.2 is ON...
also, when i first hooked the circuit up i had a little trouble with my external logic somehow interfering with the IC and it wouldn't properly turn on, so i had to delay turning on the external logic until the 63001 was on. (meant flicking 2 switches one after the other)... i created a delay using a mosfet with a capacitor and resistor on the gate but this made me wonder if the circuit on page 11 my do something like a softer startup... if i could elimit the mosfet, it would make the circuit smaller for sure...
thanks for the help mate,
