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.

The calculation module is connected to the current sensing module and is used to determine thermal state of the location of the sensing node according to the working current respectively.

Matrix thermal sensing circuit and heat dissipation system

A capacitor seat and two conductors are utilized to install a capacitor seat on a PCB by soldering the two conductors on electrical contacts of the PCB. The capacitor is installed on the capacitor seat in a fastening way such as by pressing downward, rotating the capacitor or in other feasible fastening ways to be electrically connected with the electrical contacts on the PCB. If the detachable capacitor device has errors or is damaged in use, or a user wants to replace it with a different type of the capacitors to test or adjust the characteristic of the circuit, it is easy to replace the capacitor.
