- A Robust Solution for 100-Amp Hot Swap of 12-Volt Supply RailsPDF, 318 Kb, Archivo publicado: abr 21, 2008
As intermediate bus voltages decrease, a corresponding increase in line card load currents further complicates the design of power distribution and control sub-systems in networking equipment. As one part of the overall power system, designers need a hot swap solution capable of performing its required functions while reliably surviving both normal module operation and fault conditions. But as l - TPS2490, Reverse Input Voltage BlockPDF, 56 Kb, Archivo publicado: jun 23, 2009
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, Archivo publicado: 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, Archivo publicado: dic 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 report describes the steps required to properly choose a M - Undervoltage and Overvoltage Control for the TPS2490/91 (Rev. A)PDF, 63 Kb, Revisión: A, Archivo publicado: oct 7, 2008
This application note provides a simple circuit for adding undervoltage and overvoltage control to the TPS2490 and TPS2491 hotswap controllers. - TPS2350, A High-Negative Voltage ORing ControllerPDF, 354 Kb, Archivo publicado: mayo 8, 2008
This application note addresses a method to OR the high side of the power source as well as the low side using N-channel MOSFETs, thus replacing diodes D1 and D2 with more efficient MOSFETs in the high current path. The MOSFET switch of the return current is referred to here as the high side switch. A circuit schematic for high side switching is recommended and component selection discussed.

- Surge Stopping and Reverse Voltage Protection with the LM5069PDF, 393 Kb, Archivo publicado: abr 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
