Voltage Tracking
In some applications, voltages may have to track each other as
they ramp up and down, whereas others may just need
sequencing. In these cases, tracking can be accomplished and
has been demonstrated over a wide range of load currents (1A to
10A) and load capacitances (10μF to 3300μF) with the ISL612X
family. Figure 22 and Figure 23 illustrate output voltage ramping
tracking performance. Note that differences are less than 0.5V.
With the relevant GATE pins tied together in a star pattern, so
that resistance between any two GATE pins is equivalent
(1k to 10k), GATE ramping voltage is shared. With the same or
similar enough FETs, this behavior is also observed.
It is suggested that this circuit implementation be prototyped
and evaluated for the particular expected loads prior to
committing to manufacturing build.
