FN6855.0
12V Power Distribution Controllers
This fully featured hot swap power controller targets +12V
applications. The ISL6115A with its integrated charge pump
has a higher (6.5V vs 5V) gate drive than its sister part the
ISL6115 making this part an immediate efficiency
improvement replacement.
This IC features programmable overcurrent (OC) detection,
current regulation (CR) with time delay to latch-off and soft-
start.
The current regulation level is set by 2 external resistors;
R_ISET sets the CR Vth and the other is a low ohmic sense
element across, which the CR Vth is developed. The CR
duration is set by an external capacitor on the CTIM pin,
which is charged with a 20µA current once the CR Vth level
is reached. If the voltage on the CTIM capacitor reaches
1.9V the IC then quickly pulls down the GATE output latching
off the pass FET.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish,
which is RoHS compliant and compatible with both SnPb and Pb-free
soldering operations). Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
