摘要： A power-good signal generator generates a power-good signal according to a control signal of a controller, and comprises an impedance element, a controlled transistor and a power sequencing free circuit. An end of the impedance element is coupled to a second voltage source. The controlled transistor has first and second input/output ends and a controlled end, wherein the first input/output end is coupled to the other end of the impedance element to generate the power-good signal. An operating state of the controlled transistor is changed in response to the control signal. The power sequencing free circuit is coupled to the controlled end and one of the first input/output end and the second voltage source. When the second voltage source is supplied before the first voltage source, the power sequencing free circuit turns on the controlled transistor to clamp the power-good signal to be lower than a predetermined voltage level.

摘要： A circuit for restraining a shoot through current comprises a master selecting unit and a logic unit. The master selecting unit receives an input signal, and outputs first and second master selecting signals. The logic unit comprises first and second logic elements which generate first and second control signals for controlling two transistor switches connected in series. The first and second logic elements change the logic states of the first and second control signals according to the first and second master selecting signals. When the input signal is at a first logic level, the first logic element acquires a control privilege to change the logic state of the first control signal and trigger the second logic element to change the logic state of the second control signal. When the input signal is at a second logic, the second logic element acquires the control privilege.
