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 under
voltage (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 i...
