    摘要: An electronic device includes multiple integrated circuits, each containing a power transistor connected between an input voltage node and a load node, as well as a regulation circuit generating at least one sense current representing the output current of the power transistor. The regulation circuits modulate the output currents of their power transistors based on a value derived from the sense currents generated by the regulation circuits of other integrated circuits. This derived value can be based on an average of the sense currents generated by the regulation circuits or on one of the sense currents. In particular, the integrated circuits can be arranged in a daisy-chained relationship, allowing each regulation circuit to compare its sense current with the one from the immediately preceding circuit, except for the first regulation circuit, which compares its sense current with the last circuit's sense current in the chain.

    摘要: A voltage supervisor includes a first transistor coupled between a first supply voltage and a second supply voltage. The voltage supervisor includes a second transistor coupled between the first supply voltage and the second supply voltage. The voltage supervisor is configured to provide a first current proportional to a difference in gate-to-source voltages of the first transistor and the second transistor. The voltage supervisor is also configured to provide a second current proportional to a difference in the first supply voltage and the difference in gate-to-source voltages of the first transistor and the second transistor. The voltage supervisor is configured to compare the first current to the second current to determine a voltage value that changes a state responsive to the first supply voltage crossing a threshold.
