The LTC4280IUFD#TRPBF is an integrated power management circuit that provides hot swapping, overvoltage, and overcurrent protection in an industrial-grade package suitable for almost any application. It is designed specifically to provide protection and flexibility to a power supply system, minimizing board complexity and size. The controller’s internal circuitry, along with external components, detect overvoltages and overcurrents from overcurrent sources, and coordinates the automatic insertion and removal of loads in the power supply system.

The LTC4280IUFD#TRPBF is part of the LTC4280 series of hot-swap controllers that are designed for protection and flexibility in power systems. It is a highly integrated device that provides overvoltage, overcurrent and automatic insertion/removal control. The device utilizes an internal current sense amplifier, voltage detector and two N-channel MOSFET drivers to accurately sense the input current and voltage of the system and to precisely control the power switching events. The device also features an adjustable current limit, shutdown input, and adjustable output voltage. To ensure system safety, the device can detect inadvertent remote insertion of power and automatically remove the loads in case of an overload or short circuit.

The LTC4280IUFD#TRPBF is designed to provide a highly efficient and reliable solution for hot-swap and overvoltage/overcurrent applications. The device can be used in numerous applications, such as DIN-rail power supplies, industrial machinery, computer peripherals, and consumer electronics. It is ideal for protecting sensitive trip points in the power rail. The device can be used in a wide range of Vin conditions, from 6V to 48V, and can provide up to 120W of output power. The device is available in a temperature-hardened 8-lead SOIC package and is rated for -40⁰C to 85⁰C operation.

The LTC4280IUFD#TRPBF utilizes a unique dual-mode overcurrent protection circuit to provide protection for power devices that are connected to the power rail. The device monitors the input voltage to detect overvoltages and ensue the user’s safety. If an overvoltage or short circuit is detected, the MOSFETs connected to the power rail are disabled to prevent further damage. The device also has an adjustable current limit and external shutdown input to enable the user to customize and optimize the protection settings.

The LTC4280IUFD#TRPBF also features a trip-point detection circuit that monitors the input voltage and senses when it has crossed a certain threshold. When the threshold has been met, the device can actuate the MOSFETs in order to either insert or remove the power load from the power system. The device is capable of providing up to 120W of output power with an adjustable trip-point accuracy within 10mV.

The LTC4280IUFD#TRPBF hot-swap controller is an ideal solution for devices that require hot swapping, overvoltage and overcurrent protection. Its internal monitoring circuitry is optimized for switching accuracy and its adjustable trip-point detection allows for precise calibration of the overcurrent protection thresholds. Its 8-lead SOIC package offers the user an industrial-grade solution in a highly efficient and reliable device.
