$ _' [' x5 T, Y& h* _Pin9 SS:Soft Start Pin. This pin controls the reference on the current sense amplifier. A 10 μA current source charges this pin at startup. A capacitor on this pin then sets the slope of the initial current ramp. This pin can also be driven to a voltage to alter the reference directly, thereby adjusting the current limit level with a gain of 10.
