摘要： A method, in a power supply controller, of responding to an increase in current through a terminal of the power supply controller, is disclosed. The method includes regulating the terminal to a first voltage level and sensing a magnitude of a first current through the terminal while the controller is regulating the terminal to the first voltage level. The method also includes providing an initial response by the power supply controller in response to the magnitude of the first current exceeding a first threshold current level and then regulating the terminal to a second voltage level after the magnitude of the first current exceeds the first threshold current level. The magnitude of a second current through the terminal is sensed while the controller is regulating the terminal to the second voltage level and the controller determines a final response based on the magnitude of the second current.

摘要： A method is disclosed to add functionality to a terminal of a high voltage integrated circuit without the penalty of additional high voltage circuitry. The benefit is that alternative modes of operation can be selected for testing, trimming parameters of the integrated circuit, or any other purpose without the cost of an additional terminal. In one embodiment, ordinary low voltage circuitry monitors the voltage on the terminal that normally is exposed to high voltage. The configuration of a simple voltage detector and an ordinary latch allows easy entry into the test and trimming mode when the integrated circuit is not in the intended application, but prohibits entry into the test and trimming mode when the integrated circuit operates in the intended application.

摘要： An integrated control circuit according to aspects of the present invention includes an oscillator, a capacitor, and a logic gate. The oscillator generates a periodic timing signal that cycles between a first logic state for a first time duration and a second logic state for a second time duration. The capacitor receives a charge current in response to the periodic timing signal transitioning to the first logic state, where a voltage on the capacitor increases for the first time duration to an initial value. The logic gate generates a periodic output signal having a duty ratio that is responsive to a time that it takes the capacitor to discharge from the initial value to a reference voltage. A period of the periodic output signal is the period of the periodic timing signal.
