Abstract: A circuit for protecting a transistor is disclosed. The circuit includes a temperature sensing device coupled to the transistor and a tunable clamping circuit connected between transistor terminals, wherein the tunable clamping circuit is configured to provide an adjustable clamping voltage. A temperature controller coupled to the temperature sensing device and the tunable clamping circuit is also included. The temperature controller is configured to trigger a change in a clamping voltage of the tunable clamping circuit based on a feedback from the temperature sensing device.

Abstract: The present application relates to a system and a method for determining relative positions slave units along a stub bus with at least a power line and a ground line. Each slave unit is operable in different power modes, which are differentiated by effective resistances between the power and ground lines. A reference voltage potential drop is determined for each slave unit while the slave units are operating in a first power mode. A positioning voltage potential drop is determined for one or more slave units while a selected slave unit is operating in a second power mode. Relative positions of the slave units are determined based on the relative voltage potential drops obtained from the reference and positioning voltage potential drops.

Abstract: Embodiments of a control device for an electronic fuse and a method for controlling an electronic fuse are described. Embodiments of a control device for an electronic fuse may include an interface configured to receive a current from a transistor device of the electronic fuse. Additionally, the control device may further include a sense-and-control device coupled to the interface and configured to detect an increase in the current received at the interface under a standby mode of the electronic fuse and to output an interrupt signal in response to the increase in the current received at the interface.

Abstract: An inrush current limiter for electronic fuses detects the type of load connected to the electronic fuse at ignition. By detecting the type of load, the limiter prevents a large peak current from flowing through the fuse. When a short circuit occurs, the limiter ensures that the electronic fuse only operates once in linear mode.
