Once the slow ramp period has expired, the clamp is removed, and the IRAMP voltage continues to ramp up
at a constant rate of:

IRAMP
Since the linear amplifier acts to maintain equal voltages at its inputs (see Figure 2), it slews the GATEx output
such that the CSx voltage tracks the internally generated reference at its inverting input. Therefore, the linear
voltage ramp at the IRAMP pin results in a linear current ramp to the three positive loads.
