  • A Robust Solution for 100-Amp Hot Swap of 12-Volt Supply Rails
    PDF, 318 Kb, Datei veröffentlicht: Apr 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

    PDF, 56 Kb, Datei veröffentlicht: 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 Response
    PDF, 339 Kb, Datei veröffentlicht: 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 Applications
    PDF, 500 Kb, Datei veröffentlicht: 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 report describes the steps required to properly choose a M

    PDF, 63 Kb, Revision: A, Datei veröffentlicht: 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 Controller
    PDF, 354 Kb, Datei veröffentlicht: May 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. Hi

  • Surge Stopping and Reverse Voltage Protection with the LM5069
    PDF, 393 Kb, Datei veröffentlicht: 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
