Abstract: This disclosure describes circuits and techniques for determining inductance on an electrical line. In some examples, a method comprises charging a capacitor in time steps to a voltage level; counting a number of the time steps to the voltage level, wherein the number of the time steps defines a coarse measurement inductance of the electrical line; measuring a charging rate associated with charging the capacitor within a measurement window that is defined at the voltage level, wherein the charging rate associated with charging the capacitor within the measurement window defines a fine measurement of the inductance of the electrical line; and outputting an indication of the number of time steps and an indication of the charging rate associated with charging the capacitor within the measurement window.

Abstract: In some examples, a device includes a memory configured to store a pre-warning threshold level for a parameter of a power switch. The device also includes a logic circuit configured to receive a signal from a controller and set the pre-warning threshold level in response to receiving the signal from the controller. The logic circuit is also configured to determine that a magnitude of the parameter of the power switch does not satisfy the pre-warning threshold level. The logic circuit is further configured to output an alert to the controller in response to determining that the magnitude of the parameter does not satisfy the pre-warning threshold level.

Abstract: A driver circuit is configured control one or more bypass transistors. The driver circuit includes a primary supply input connection configured to supply the driver circuit with power from a set of battery cells. The set of battery cells is configured to supply power to a load via a power delivery circuit. The driver circuit also includes one or more secondary supply input connections. The driver circuit is configured to receive information indicating whether an error condition is present in the power delivery circuit and control, based on the error condition being present in the power delivery circuit, the one or more bypass transistors to define a bypass current path. The driver circuit is also configured to receive, via a secondary supply input connection of the one or more secondary supply input connections, power from the bypass current path.

Abstract: A controller circuit is configured to receive, from a first device, a first node voltage measured at a first node by the first device at a first time when a first current flows between the first node and a second node and receive, from a second device, a second node voltage measured at a second node by the second device at a second time when a second current flows between the first node and the second node, wherein the first time is different from the second time. The controller circuit is further configured to, responsive to a determination that the first current corresponds to the second current, calculate, using the first node voltage and the second node voltage, a resistance value for one or more electrical components electrically connecting the first node and the second node.
