Power Distribution Controllers
This family of fully featured hot swap power controllers
targets applications in the +2.5V to +12V range. The
ISL6115 is for +12V control, the ISL6116 for +5V, the
ISL6117 for +3.3V and the ISL6120 for +2.5V control
applications. Each has a hard wired undervoltage (UV)
monitoring and reporting threshold level approximately 80%
of the aforementioned voltage.
The ISL6115 has an integrated charge pump allowing
control of up to +16V rails using an external N-Channel
MOSFET whereas the other devices utilize the +12V bias
voltage to fully enhance the N-channel pass FET. All ICs
feature 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 cap reaches 1.9V the
IC then quickly pulls down the GATE output latching off the
pass FET.
This family although designed for high side switch control the
ISL6116, ISL6117, ISL6120 can also be used in a low side
configuration for control of much higher voltage potentials.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
