The LTC4240CGN#PBF is a hot-swap controller designed for power delivery to cards plugged into regulated hot-swappable systems. It is a versatile controller for controlling up to three current-limited power delivery paths in power systems. The LTC4240CGN#PBF is part of the Power Management IC (PMIC) family, specifically Hot Swap Controllers.

Application Field

The LTC4240CGN#PBFis commonly used in applications such as enterprise servers and telecom hubs, which require hot-swap controllers that are capable of handling a variety of applications. The LTC4240CGN#PBF offers a low quiescent current operation and a wide range of operating voltages, making it ideal for data center applications, or powering off PCI-Express cards with fast auto-regulation capabilities for improved system performance. It is also suitable for applications in automotive, consumer electronics and military/aerospace applications.

Working Principle

The LTC4240CGN#PBF is designed to deliver up to three isolated outputs with automatic current-limiting protection. The device monitors both the output voltage and the current drawn by the load in each of its three channels. Each output has independent overcurrent, overvoltage, and overtemperature protection with indicator LEDs that respond to sensor conditions. The LTC4240CGN#PBF also features a precision voltage reference that provides an accurate feedback voltage, which allows the device to accurately monitor the output voltage.

The LTC4240CGN#PBF also provides an adjustable soft-start circuit, which prevents large inrush currents that can occur when hot-plugging a high power load into the system. This feature also minimizes voltage overshoots and the possibility of system reset.

The LTC4240CGN#PBF also features adjustable current-limit protection, in which the user can selectcurrent-limiting levels based on the power system requirements. The device adjusts the current-limiting levels as the output voltage varies, reducing the risk of catastrophic overcurrent events.

In addition, the LTC4240CGN#PBF includes a remote enable(RE) pin that allows the user to enable and disable the power delivery paths. This feature allows the user to disconnect one or more of the power paths as needed. The device also includes a logic enable(LE) input to enable or disable the logic portion of the device separately from the power delivery portion.

Conclusion

The LTC4240CGN#PBF is a versatile hot-swap controller designed for controlling up to three current-limited power delivery paths. It features low quiescent current operation, wide range of operating voltages, adjustable soft-start, adjustable current-limit protection and capability to enable and disable power paths through logic pins. The device is suitable for many applications such as enterprise servers and telecom hubs, automotive, consumer electronics and military/aerospace applications.
