If the input voltage to a TPS249X controlled system is reversed, The TPS249X will bedestroyed and the load will be exposed to the reverse voltage. This app note proposesa solution for both. A schematic is shown and design consideration noted for each pin. - Hotswap Design Using TPS2490/91 and MOSFET Transient Thermal ResponsePDF, 339 Kb, File published: Jul 21, 2004
Hotswap circuits rely on the thermal capacitance of the series-limiting MOSFET to dissipate the large transient energy under current- or power-limit operation. The peakjunction temperature must be controlled in order to achieve a robust design. The constant-power MOSFET protection of the TPS2490 provides a simple method to useinformation provided by MOSFET manufacturers to determine peak junct - Selecting Transistors for Hot-swap ApplicationsPDF, 500 Kb, File published: Dec 16, 2009
In hot-swap circuits, series-limiting devices such as MOSFETs are used to control start-up inrush and fault currents. During these transient events, the MOSFET dissipates power greater than steady-state and can well exceed the thermal limits of the MOSFET. These factors require consideration when selecting the MOSFET.

This application note provides a simple circuit for adding undervoltage and overvoltage control to the TPS2490 and TPS2491 hotswap controllers. - Hot Plug Express CardPDF, 99 Kb, File published: Sep 23, 2005
- Surge Stopping and Reverse Voltage Protection with the LM5069PDF, 393 Kb, File published: Apr 11, 2013
Many automotive and industrial applications require protection from a wide range of input supply insertion errors and voltage surges. Automotive voltage rails can exceed 40V during a load dump event, and at the same time, protection circuitry can encounter negative voltage surges below -24V during a reversal of the battery polarities. Several devices are available to block or clamp these events, h
