Abstract: A battery cell monitoring circuit comprises an input pin; a reset command detection circuit comprising an integrator circuit coupled to the input pin; a counter circuit coupled to an output terminal of the integrator circuit; and a one-shot circuit coupled to an output terminal of the counter circuit; a logic gate coupled to an output terminal of the one-shot circuit; and a reset circuit coupled to the logic gate.

Abstract: At least some aspects of the disclosure provide for a system. In at least some examples, the system includes a microcontroller, an energy storage element, a monitoring circuit, and a communication bridge. The monitoring circuit is coupled to the energy storage element and configured to determine whether a fault associated with the energy storage element is present, generate an indication of the fault when the fault with the energy storage element is present, and transmit the indication of the fault. The communication bridge is configured to receive the indication of the fault and assert a fault signal and transmit the fault signal to the microcontroller.

Abstract: A battery pack includes a housing, a battery, a battery pack output voltage path that includes a charge power switch and a discharge power switch, and a battery sense output. A switch can be operably coupled between the battery and the battery sense output and configured to selectively open and close a battery sense path between the battery and the battery sense output. By one approach a first control circuit controls the open and close state of the aforementioned switch (in response, for example, to a comparison of the voltage differential across the switch to a predetermined threshold such that the switch is opened when the voltage differential across the switch becomes too positive or too negative with respect to battery voltage).
