  • Method for extending the diagnostic capability of current regulators
    Patent number: 8421487
    Abstract: A method and a device for monitoring at least one output stage for an inductive load using a current regulator and an analysis device are described. A short circuit to a power supply or to ground is detected by comparing at least one current value in a switching phase of the at least one output stage with at least one current value in a free-wheeling phase of the at least one output stage.
    Type: Grant
    Filed: April 30, 2007
    Date of Patent: April 16, 2013
    Assignee: Robert Bosch GmbH
    Inventors: Christian Lammers, Jochen Neumeister, Hans Raub, Steffen Reinhardt, Danilo Marcato

  • Integrated overload protective device
    Patent number: 5969927
    Abstract: An overload protective device for integrated components that responds rapidly to transient local temperature increases to protect the respective component from overload or overheating. The protective device includes an ohmic measuring resistor made of metal, aluminum in particular, that is integrated into the component. Temperature increases and power loss in individual transistor cells can thus be detected reliably.
