Latest Patents

One of his key patents is titled "Power system and short-circuit protection circuit thereof." This invention provides a short-circuit protection circuit adapted to a voltage regulator module. The voltage regulator module includes a high side transistor and a low side transistor. The short-circuit protection circuit consists of 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, while the low side transistor is coupled with a ground. The first switch is connected with the low side transistor in parallel, and the second switch is coupled between the high side transistor and the power supply. The first switch is turned on before the power supply is powered on, allowing the short-circuit detecting circuit to send a detecting voltage to the high side transistor via the detecting terminal to determine whether the high side transistor is short-circuited, thus controlling the second switch.
