ISL6115, ISL6116, ISL6117, ISL6120

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;

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.
