COLD-CRANK EVENT MANAGEMENT

摘要

Systems and methods for managing cold-crank events. In an embodiment, a method may include detecting a cold-crank event and setting a switching circuit to a non-conductive state, where the switching circuit is configured to couple a first regulator to a memory circuit such that setting the switching circuit to the non-conductive state de-couples the memory circuit from the first regulator. The method may also include setting the switching circuit to a conductive state in current limitation mode during a recovery period following the cold-crank event to re-couple the memory circuit to the first regulator. In another embodiment, an electronic device include a switching circuit, a first regulator coupled to a first terminal of the switching circuit, a second regulator coupled to a second terminal of the switching circuit, a logic circuit coupled to the switching circuit, and a memory circuit coupled to the second terminal of the switching circuit.

1. A method, comprising:
detecting a cold-crank event; in response to detecting the cold-crank event, setting a switching circuit to a non-conductive state, wherein the switching circuit is configured to couple a first power regulator to a memory circuit, and wherein setting the switching circuit to the non-conductive state de-couples the memory circuit from the first power regulator; and setting the switching circuit to a conductive state in current limitation mode during a recovery period following the cold-crank event, wherein setting the switching circuit to the conductive state re-couples the memory circuit to the first power regulator.
