摘要:
An electrical reset circuit is configured to generate a reset pulse to reset one or more electrical components. The electrical reset circuit includes a first device electrically connected between a power supply input and a first node. The first device is configured to conduct current after the power supply input reaches a first voltage threshold. The electrical reset circuit also includes a second device electrically connected between the power supply input and a second node, where the second device is configured to conduct current after the power supply input reaches a second voltage threshold. In some examples, the electrical circuit includes a delay circuit configured to delay the reset pulse. Corresponding methods to providing a reset pulse are also contemplated.
