The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

or you can measure open-circuit voltage, but neither method properly tests the battery. A suitable test current of approximately 250 mA gives you a more reasonable test. You can use a 6Ω resistive ...

This dummy-load circuit, which is useful for testing power supplies and power amplifiers, is based on the Maxim MAX6006 voltage-reference IC and MAX480 operational amplifier. This dummy-load ...

The Need for Load-Dump Protection 1. Typical load-dump condition circuit. Within Paragraph 4.6, titled “Discontinuities in supply voltage,” is sub-section 4.6.4 Load Dump. A load dump occurs ...
