Abstract: An electronic package that has an array of pins may be tested for shorts and continuity in a parallel manner. The array of pins are allocated to four or more groups of pins such that each pin in each group is not adjacent to a pin from its own group of pins.

A short between one of the pins in the first group and a pin in one of the other groups can be detected when the resultant voltage on one of the pins in the first group is approximately equal to the reference voltage. Group-wise testing is repeated until all groups have been tested.

Abstract: A device for measuring the value of a resistor has a first RC element with a first time constant and a second RC element with a second time constant. The first RC element has a first capacitor and a resistor. The second RC element has a second capacitor and the resistor to be measured. An evaluation circuit charges the first and second capacitors to a first and a second voltage, respectively, and initiates their discharge. The evaluation circuit measures the time that elapses from the start of the discharge to the instant at which the voltages across the capacitors are equal, and determines the value of the resistor from the values. In the event that the first time constant is larger than the second time constant, the first voltage is smaller than the second voltage, and vice versa.

Abstract: An electronic package having multiple pins may be tested in parallel for output short circuit current by simulating a direct short to ground by simultaneously connecting multiple output pins directly to ground in order to active a current limiter associated with each of the output pins. The pins are then connected to a resistive connection to ground via a set of resistors; the direct ground is then removed, such that the current limiter associated with each of the output pins remains activated. A voltage drop across each of the set of resistors is measured simultaneously. An output short circuit current fault is indicated when the voltage drop across any of the resistors exceeds a threshold value corresponding to a maximum output short circuit current value.

Abstract: Provided is a magnetic field detection device and a current sensor capable of increasing the degree of freedom in selecting the type of the magnetic field detection element. A magnetic field detection device 1 includes a conductor 3 that generates a magnetic field; a C core 2 provided so as to surround the conductor 3; and a magnetic field detection element 4 that detects a magnetic field. The C core 2 has a gap G1, and the magnetic field detection element 4 is disposed at a position where the magnetic field generated from the conductor 3 can be detected, the position being outside the gap G1. Since the direction of the magnetic flux varies outside of the gap G1 from place to place, the direction of the magnetic flux that passes through the magnetic field detection element 4 can be arbitrarily selected by arbitrarily selecting the installation location of the magnetic field detection element 4. Therefore, the degree of freedom in selecting the type of the magnetic field detection element 4 is increased.
