Abstract
An first embodiment relates to a device comprising: a first semiconductor switch; an integrated sensor for determining a current that passes the first semiconductor switch; and a terminal to which a signal is provided in case the current fulfills a predetermined condition. Also, a system comprising such device, and a method of operation are suggested.
Claims20
A device comprising:
- a semiconductor switch;
- a terminal;
- and
- an integrated sensor configured to:
- receive a first signal from a microcontroller indicating that the microcontroller is entering an idle mode;
- responsive to receiving the first signal, determine whether a current that passes the semiconductor switch fulfills a predetermined condition;
- and
- responsive to determining that the current fulfills the predetermined condition, deliver a second signal to the terminal to wake up the microcontroller from the idle mode.

A system comprising:
- a processing unit;
- and
- a device including:
- a semiconductor switch;
- a terminal connected to the processing unit;
- and
- an integrated sensor configured to:
- receive a first signal from the processing unit indicating that the processing unit is entering an idle mode;
- responsive to receiving the first signal, determine whether a current that passes the semiconductor switch fulfills a predetermined condition;
- and
- responsive to determining that the current fulfills the predetermined condition, deliver a second signal to the terminal,

9 more elements
A method comprising:
- receiving a first signal from a processing unit indicating that the microcontroller is entering an idle mode;
- responsive to receiving the first signal, determining, via a sensor, whether a current that passes a semiconductor device fulfills a predetermined condition, wherein the sensor and the semiconductor device are part of a single device;
- responsive to determining that the current fulfills the predetermined condition, delivering a second signal to a processing unit;
- and
- waking up the processing unit from the idle mode based on the second signal.
