Figure 2 illustrates the turn-on and Figure 3 illustrates the
nominal turnoff timing diagram of the ISL6123 and ISL6124
product.
The ISL6125 is similar to the ISL6124 except that instead of
charge pumped GATE outputs, there are sequenced open
drain outputs that can be pulled up to a maximum of V
Note the delay and flexible sequencing possibilities. Multiple
series, parallel or adjustable capacitors can be used to easily
fine tune timing between that offered by standard value
capacitors.
