Soft-start
When both V
CC
and V
IN
are above their turn-on thresholds (V
IN
is monitored by the OCH pin)
the start-up phase takes place. Otherwise the SS pin is internally shorted to GND. At start-up, a
ramp is generated charging the external capacitor C
SS
with an internal current generator. The
initial value for this current is 35μA and charges the capacitor up to 0.5V. After that it becomes
10μA until the final charge value of approximately 4V (see
Figure 5.
).
