Abstract:
A short-circuit protection circuit adapted to a voltage regulator module is provided. The voltage regulator module includes a high side transistor and a low side transistor. The short-circuit protection circuit includes a short-circuit detecting circuit, a first switch, and a second switch. The short-circuit detecting circuit includes a detecting terminal coupled with the high side transistor. The high side transistor is connected with the low side transistor and a load, and the low side transistor is coupled with a ground. The first switch is connected with the low side transistor in parallel. The second switch coupled between the high side transistor and the power supply. The first switch is turned on before the power supply is powered on, the short-circuit detecting circuit sends a detecting voltage to the high side transistor via the detecting terminal to determine whether the high side transistor is short-circuited to control to second switch.
Abstract:
A remote control system includes a remote control device and an electronic device. The remote control device includes an input element, a wireless transmitter to transmit an absolute coordinate signal and a motion signal and a control unit electrically connected to the input element and the wireless transmitter. The electronic device includes a wireless receiver and a display screen. The wireless receiver receives the absolute coordinate signal and the motion signal, and displays the absolute coordinate signal at the display screen via a cursor. When the electronic device does not receive the motion signal, the absolute coordinate signal is not operated on an application program of the electronic device. When the electronic device receives the motion signal, the absolute coordinate signal is operated on the application program.
