The ISL6142CB is a PMIC (Power Management Integrated Circuit) unit that is part of the Hot Swap Controller family. This device was designed to serve as a solution for installing, pre-charging, and protecting power rails found in many applications. The ISL6142CB integrates an accurate internal reference voltage source along with a low quiescent current high PSRR Operational Amplifier (Op Amp) to control voltage levels, while also providing over-current protection.

The input voltage of the ISL6142CB is nominally set between 4 - 58 V with a 10V minimum under load, and the output voltage can be programmed with externally adjustable resistors. It has built in over-temperature and under-voltage protection as well as an accurate voltage folding function that folds back an output that senses a drop below the set point to ensure an output settling with less than 1mV of error.

The ISL6142CB integrates a high accuracy voltage reference and a differential Op Amp with low quiescent current levels. This enables the unit to accurately monitor, regulate, and protect any pre-specified voltage settings for relevant applications like for power supply applications and circuit protection in computing, automotive, and other industrial fields, as well as telecommunications, networking, and even military applications.

These controllers provide applications with improved operational precision and control in terms of DC and AC voltage inputs, power supplies and dynamic loads. The controllers also have a wide selection of settings for under-voltage, over-voltage, over-temperature, short-circuit and other flag settings for fault protection for the attached circuits. This helps to improve system protection, system regulation, and more efficient use of power in the connected devices.

The ISL6142CB is a smart and cost effective hot-swap controller that is available in a compact 8-lead SOIC package and is RoHS compliant, so it can be used to safely minimize interruption in applications where live insertion, hot plugging, and/or safe removal of circuit boards are foreseeable. An ENABLE input is also available to control when power is allowed to flow through the system.

All in all, the ISL6142CB is a powerful, cost-effective addition to any PMIC family, providing safe and efficient enabling and over-current protection for power rails in a variety of applications. Its easy implementation and wide applications make it a perfect solution for any task requiring accurate and reliable control of power or voltage levels.
