Abstract: A multiplexer comprises: a first switch; a second switch; a dummy component coupled to the first switch and the second switch and configured to: reduce a first charge injection of the first switch, and reduce a second charge injection of the second switch; and an output coupled to the first switch, the second switch, and the dummy component. A method comprises: providing an output from either a first switch or a second switch; coupling, by a dummy component, to the first switch and the second switch; using a BBM action; and reducing, by the dummy component, a first charge injection of the first switch or a second charge injection of the second switch.

Abstract: In an example, a system includes a first transistor and a second transistor, the first transistor and the second transistor configured to provide current to a load. The system also includes a sense transistor coupled to the first transistor, the sense transistor configured to sense a current flowing through the first transistor. The system includes an amplifier coupled to the sense transistor, where the amplifier includes a first input, a second input, and an output. The system also includes pre-bias circuitry coupled to the amplifier, where the pre-bias circuitry is configured to provide a voltage to the first input of the amplifier responsive to the first transistor being off, where the voltage biases the amplifier.

Abstract: A device includes FETs with control terminals. A gate driver circuit causes the FETs to turn on and to enter a high-impedance state in response to an OCP signal. A current sense circuit senses an FET current through the FETs and sends the OCP signal to the gate driver circuit when the FET current exceeds an OCP current for longer than an OCP deglitch period. A test sequencer, in response to receiving an external test mode signal, sets the OCP current to a preset OCP test current, sets the OCP deglitch period to a preset OCP deglitch test period, and causes the gate driver circuit to turn on the plurality of FETs.
