Abstract: Embodiments are directed to electronic fuse devices and systems. One such electronic fuse includes current sensing circuitry that senses a current in a conductor coupled between a power supply and a load, and generates a current sensing signal indicative of the sensed current. I2t circuitry receives the current sensing signal and determines whether the sensed current exceeds an I2t curve of the conductor. The electronic fuse further includes at least one of external MOSFET temperature sensing circuitry that senses a temperature of an external MOSFET coupled to the conductor, low current bypass circuitry that supplies a reduced current to the load in a low power consumption mode during which the external MOSFET is in a non-conductive state, or desaturation sensing circuitry that senses a drain-source voltage of the external MOSFET.

Abstract: An electronic module for generating light pulses includes an electronic card or interposer, a LASER-diode lighting module, and a LASER-diode driver module. The interposer has an edge recess in which the lighting module is completely inserted. The driver module is arranged on top of the interposer and the lighting module. The electrical connections for driving the LASER diodes are obtained without resorting to wire bonding in order to reduce the parasitic inductances.
