20110261495 | E-fuse System For Supplying Current To A Load Along More Than One Path - An electronic fuse system includes plural current paths, each operable to be coupled between a power source and a load, and each including a switching element and a current sensing resistor in series with the path such that the path passes current when the switching element is turned on and does not pass current when the switching element is turned off. A controller has two sense inputs and a control output. The control output is coupled to the switching elements in each of the plural current paths and is operable to turn them all on or off simultaneously responsive at least in part to the sense inputs. A summing resistor is connected across the two sense inputs, and coupling circuitry is operable to couple voltages appearing across the current sensing resistors to the summing resistor. | 10-27-2011 |
20120119775 | CIRCUITRY FOR HOT-SWAPPABLE CIRCUIT BOARDS - Electronic circuits and methods are provided for use in hot-swappable circuit board applications. Circuitry detects an electrical ground connection and signals operation of a hot-swap controller. Detection of stable operating power causes a hierarchical startup of plural voltage regulators. Sensing stable output power from the last of the voltage regulators triggers the configuration of one or more programmable devices. Circuitry and other resources of a hot-swappable circuit board are protected against electrical transient-related damage by virtue of the present teachings. | 05-17-2012 |

20080239593 | Failure detection in a voltage regulator - A control logic detects voltage regulator failure in a power supply. The control logic comprises first and second lines configured for respective connection to a controller node and a phase node of a voltage regulator, a delay element coupled to the first line configured to delay signals at the controller node into alignment with signals at the phase node, and a level detector coupled to the second line configured to convert the signals at the phase node into at least two digital representations indicative of respective signal thresholds. A logic compares timing of the delayed signals with the digital representations and detects occurrence of a voltage regulator fault based on the timing comparison. | 10-02-2008 |

20110133713 | DC-TO-DC CONVERTER WITH INDEPENDENT COMPENSATION LOGIC - An apparatus comprises a direct current (“DC”) to DC converter comprising a first compensation logic and other DC to DC converter logic. The first compensation logic compensates for phase shifts in an output of the DC to DC converter. The first compensation logic is disabled independently of the other DC to DC converter logic based on a first communication sent to the DC to DC converter. | 06-09-2011 |

20150121187 | METHOD TO VISUALIZE END USER RESPONSE TIME - A method for visual representation of EURT is provided. Measurements of performance parameters are collected. Each of the performance parameters corresponds to at least one performance problem domain. The performance parameters include at least a first, second and third parameters. A correlation between at least two of performance parameters is determined. A first graph having a first region representing the first parameter and having a second region representing the second parameter is presented to a user. The first and second regions extend in substantially opposing directions. A second graph representing the third parameter based on the determined correlation between data elements falling within each of the respective performance problem domains is simultaneously presented to the user. The first, second and third parameters are components of the EURT. | 04-30-2015 |
