摘要： A one-time programmable (OTP) circuit. The OTP circuit includes a non-volatile OTP memory disposed on a first circuit die. The OTP memory includes a floating gate terminal. The OTP circuit also includes a cross-coupled latch disposed on the first circuit die and coupled to the OTP memory and volatile memory input circuitry disposed on the first circuit die and coupled to the cross-coupled latch. The volatile memory input circuitry is configured to receive a test value and write the test value into the cross-coupled latch. The OTP circuit is configured to receive a programming command and store the test value in the OTP memory in response to receipt of the programming command.

摘要： 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.

摘要： 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.

摘要： A current detection system includes an inductor and a detection circuit coupled across the inductor. The inductor is configured to receive an input signal that includes an input current and generate a voltage across the inductor. The current detection circuit includes a sensing network and a transconductance amplifier. The sensing network includes a capacitor and is configured to monitor a voltage across the inductor. The transconductance amplifier is configured to receive a differential voltage indicative of a voltage drop across the capacitor and output a differential output current proportional to the differential voltage.
