    摘要: In one example, a circuit includes an input, an output, and a control module. The input is configured to receive a control signal indicating whether to activate or deactivate a load. The output is configured to supply current to activate the load. The control module is configured to determine whether a state of the circuit is a low current consumption mode (LCCM). In response to determining that the state of the circuit is not the LCCM, the control module is configured to determine whether the control signal indicates to activate the load and output, at the output, the current to activate the load. In response to determining that the state of the circuit is the LCCM, the control module is configured to ignore the control signal indicating whether to activate or deactivate the load and output, at the output, the current to activate the load.

    摘要: A power switch module for an electronic device includes a flip-flop circuit, a first current path for coupling a voltage source to the flip-flop circuit, and a second current path for coupling the voltage source to the flip-flop circuit. In response to a user power-on event, an output of the flip-flop circuit is at a first logic state for normally powering on the electronic device. In response to a user power-off event, the output of the flip-flop circuit is at a second logic state for normally powering off the electronic device. When the voltage source is suddenly interrupted, the output of the flip-flop circuit is kept at the first logic state but the electronic device is abnormally powered off. After the voltage source is resumed, the output of the flip-flop circuit kept at the first logic state reboots the abnormally powered-off electronic device.

    摘要: A system for detecting the assertion of a reset signal. A plurality of circuit elements is configurable by a reset signal to output a string of data values in a predetermined pattern. A comparator receives the string of data values and determines whether the string of data values matches the predetermined pattern. If so, the comparator generates an output signal indicative of a reset. In one embodiment, the output signal of the comparator can be used to automatically trigger a reset if the reset signal has not been asserted.
