摘要： A load switch circuit (100) includes a driver (112) to control a gate (114) of a transistor. The gate (114) enables the transistor to deliver power to a load from a power supply (130) when the gate (114) is activated. A gate slope control (116) controls a rate of change over time of a voltage associated with the gate (114) to activate the gate (114) and to disable the driver (112) when the gate (114) is activated.

摘要： An example power multiplexer (100) includes: a first transistor (105) coupled to a first input (102); a second transistor (106) coupled to the first transistor (105) to couple a first voltage at the first input (102) to an output (101); a third transistor coupled to a second input; a fourth transistor coupled to the third transistor to couple a second voltage at the second input to the output (101); a diode amplifier (142) to provide a third voltage to a gate (105C) of the first transistor (105) to block a reverse current; and a soft-start amplifier to provide a fourth voltage to a gate of the fourth transistor to turn on the fourth transistor with a constant ramp rate.

摘要： In described examples of a switch (200) for controlling a power supply, the switch (200) includes a first transistor (Ml) having a drain and a source connected between V IN and V OUT and a gate connected to be driven to a first voltage that is greater than VIN, an external capacitor (C EXT ) operable, when connected to the gate of the first transistor (Ml), to control a rise time of V OUT , and a circuit coupled to the gate of the first transistor (Ml) and to the external capacitor (C EXT ). The circuit is connected to couple the external capacitor (C EXT ) to the gate of the first transistor (Ml) responsive to an enable signal (EN) turning on and to uncouple the external capacitor (C EXT ) from the gate of the first transistor (Ml) responsive to the voltage on the gate reaching the first voltage.
