The MAX5978ETJ+T is a fully integrated power hot-swap controller for flexible and efficient power management of on-board hot swap applications. It features a high-voltage MOSFET power stop switch, hot-swap start-up sequencing, undervoltage, foldback current limit, inrush current limit, and programmable overvoltage tracking capability. This device is specifically designed to provide power control and hot swap control capabilities to systems operating from either a positive or negative voltage. The MAX5978ETJ+T is located in the ‘PMIC - Hot Swap Controllers’ categories, featuring a high level of integration, using minimal external components, and saving board space.

Generally, the MAX5978ETJ+T provides two switch outputs, an error output, a high voltage power stop switch, and a load current sensing circuit, which can detect the load current that is being routed through the high voltage MOSFET. The device further comprises a voltage supervisor input, a feedback input, and a programmable timer output.

The MAX5978ETJ+T device has a wide operating voltage range, from -50V to 50V. Its hot-swap input pin features both high voltage and low voltage tolerance, allowing for powering up or down in both high and low voltage domains. It also features fast hot swap response times and low power consumption. The MAX5978ETJ+T provides overvoltage protection, eliminating the risk of damage even at high voltage levels.
