More Information
Summary:In an embodiment, a semiconductor device is disclosed. The semiconductor device includes a plurality of output pins. Each of the output pins is electrically connected to an input pin of a buzzer and to a buzzer driver. The buzzer driver is configured to cause the buzzer to emit an audible sound. The semiconductor device further includes a plurality of ground switches. Each ground switch is configured to connect a corresponding output pin of the plurality of output pins to ground when closed. The semiconductor device further includes a current generator that is configured to supply a test current to a given output pin of the plurality of output pins and a clamp switch that is configured to connect the given output pin to an analog-to-digital converter.
