Abstract: A multi-channel ADC system may include a plurality of input channels coupled to input signals. A multiplexer may couple one or more of the plurality of input channels to one or more multiplexer output channels. A control circuit may be coupled between the multiplexer output channels and an ADC. In operation, a configuration setting may configure the multi-channel ADC system in one of a plurality of configurations, including but not limited to single-ended, differential, pseudo-differential and hybrid configurations. The ADC may convert the plurality of input channels based on the configuration setting.

Abstract: An ADC system may include an ADC, a comparator, a voltage source, a comparator output polarity control circuit and a comparator output counter. An analog input signal may be input to a first input of the comparator, and an output of the voltage source may be input to a second input of the comparator. The comparator may generate an output to the comparator output polarity control circuit, and the comparator output counter may count clock cycles while the comparator output is asserted and may assert a monitor output based on the comparator output counter value. The monitor output may be an interrupt, an alarm or other system alerts and may control system operation.

Abstract: A method, device and system for efficient allocation of an available current supply to a first and second USB power port. The current drawn by a device connected to the first power port is measured and the first power port designated as a priority port. A first current limit is assigned to the priority port, where the selected first current limit is the lowest available current limit setting that is greater than the measured current draw on the priority port. A second current limit is assigned to the second power port, where the assigned second current limit is the highest available current limit setting that is less than or equal to the available current minus the first current limit. The current drawn on the priority port is periodically measured and the first current limit and the second current limit are adjusted accordingly to efficiently distribute the available current.
