Inventor: RICHARD S LUCKY
IPC: G01R27/08
Filed: 2021-06-23
Abstract: Disclosed are circuits for measuring leakage current of one or more capacitors coupled to a power supply line supplying power to an apparatus such as a storage device. According to one embodiment of the present invention, the circuit comprises first and second resistors between first and second switches for a power supply line and the ground, respectively. A controller can charge a voltage line with a first voltage. The controller then discharges the first voltage as a second voltage through the first resistor for a first identified amount of time. After recharging the voltage line, the controller discharges the first voltage as the second voltage through at least the second resistor for a second identified amount of time. The controller determines a parasitic resistance by using the first and second identification times and a leakage current from the parasitic resistance. In addition, eliminating a leakage current factor from subsequent measurements can greatly increase test accuracy and false positives can be avoided in a test process requiring removal of otherwise properly functioning drives or other systems.
