摘要： A driving protection circuit is coupled to a load via an input/output pin. A signal generator circuit is configured to generate a driving signal. An input/output circuit transmits the driving signal to the input/output pin according to an enable signal. A counter circuit adjusts the count value when the enable signal is at a predetermined level. A detection circuit detects the voltage level of the input/output pin to generate a detection signal. When the count value is equal to a predetermined value, a control circuit determines whether the level of the detection signal is the same as the level of the driving signal. When the level of the detection signal is not the same as the level of the driving signal, the control circuit sends an error signal to turn off power to the load.

摘要： An input/output (I/O) buffer circuit includes an I/O unit and a protection circuit. The I/O unit selectively receives and outputs signals based on an enable signal. The protection circuit generates a logic control signal to deactivate the I/O unit in a state where a voltage level of the I/O terminal is abnormal. The protection circuit includes a register. The register latches a logic signal corresponding to the voltage level of the I/O terminal in a state where the voltage level of the I/O terminal is abnormal, outputs the logic control signal based on the logic signal, and is preset to output the logic control signal based on the logic signal when a power-off state resumes to a power-on state.

摘要： A fluid flow metering device and a method thereof are provided. The fluid flow metering device includes a fluid flow detector, a memory, a micro controller and a power generator. The fluid flow detector is disposed in a supply tube of a fluid flow provider. When the fluid flows in the supply tube, the power generator generates a supplying power through flow of the fluid, and provides the supplying power to the fluid flow detector, the memory and the micro controller. When the fluid flow detector detects the flow of the fluid, the fluid flow detector detects the flow of the fluid outputted from the supply tube to derive a detecting value. The micro controller receives the detecting value and writes the detecting value into the memory, or the micro controller converts the detecting value into a flow value and writes the flow value into the memory.

摘要： A sensing device includes a comparator, a first and a second variable capacitor unit. A first comparator input of the comparator is electrically coupled to a touch pad. The first variable capacitor unit is configured to charge the first comparator input such that the first comparator input has a first potential. The second variable capacitor unit is configured to charge a second comparator input of the comparator such that the second comparator input has a second potential. The comparator is configured for comparing the first potential and the second potential to generate a comparator output signal. In a condition of the touch pad being operated, the first variable capacitor unit is adjusted according to the comparator output signal to perform potential compensation for the first comparator input, or the second variable capacitor unit is adjusted according to the comparator output signal to perform potential compensation for the second comparator input.

摘要： A sensing device includes a comparator, a first switch, a second switch, and a controller. The comparator includes a first input end and a second input end. An end of the first switch is connected to one of a first touch electrode and a second touch electrode that are complementary. An end of the second switch is selectively connected to the second touch electrode. When the first touch electrode and the second touch electrode are touched, the controller controls the first switch to connect the first input end and the first touch electrode, controls the second switch to connect the second input end and the second touch electrode, and calculates a first touch position of the first touch electrode and the second touch electrode.
