Power Distribution Controllers
ISL6115, ISL6116, ISL6117,
ISL6120
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; RISET 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.
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.
