APPLICATIO S I FOR ATIO

The current through R

The capacitive load typically dominates.
For a successful start-up without current limit, I

Due to the voltage follower configuration, the V
rate approximately tracks V
At time point 6, V
up continues until it reaches a maximum voltage. This
maximum voltage is determined either by the charge
pump or the internal clamp.
Start-Up Cycle With Current Limit
If the duration of the current limit is brief during start-up
(Figure 4) and it did not last beyond the circuit breaker
function time out, the GATE behaves the same as in start-
up without current limit except for the time interval be-
tween time point 5A and time point 5B. The servo amplifier
