    Abstract: In some examples, a circuit includes a state machine. The state machine is configured to operate in a first state in which the state machine gates a pulse width modulation (PWM) signal provided for control of a power converter according to a first signal provided by a voltage control loop. The state machine is configured to operate in a second state in which the state machine gates the PWM signal according to a second signal provided by a current limit comparator. The state machine is configured to transition from the first state to the second state responsive to the second signal being asserted after the first signal is asserted in a switching cycle of the power converter. The state machine is configured to transition from the current state to the first state responsive to the first signal being asserted after the second signal in a switching cycle of the power converter.

    Abstract: An example multiphase power converter circuit includes a first power stage is configured to provide a first phase output signal at a first switching output based on a first control signal. The first power stage includes first open fault detection circuitry configured to disable detecting and/or reporting of an open fault condition responsive to the first control signal. A second power stage is configured to provide a second phase output signal at a second switching output based on a second control signal. The second power stage includes second open fault detection circuitry configured to enable detecting and/or reporting of the open fault condition responsive to the second control signal having a value to turn off the second power stage. The second open fault detection circuitry is further configured to detect the open fault condition based on a voltage at the second switching output.

    Abstract: In at least some examples, an integrated circuit includes an input pin and an analog-to-digital converter (ADC) comprising an input terminal coupled to the input pin and an output terminal. The integrated circuit further includes a logic circuit comprising an input terminal coupled to the output terminal of the ADC, a first output terminal, and a second output terminal. The integrated circuit further includes a resistance circuit. In an example, the resistance circuit includes a resistor coupled between the input pin and a first node, a first switch coupled between the first node and a reference voltage pin, and a second switch coupled between the first node and a ground pin.
