  • Publication number: 20220294213
    Abstract: An electrostatic discharge (ESD) protection circuit is provided to minimize ESD damage to an internal circuit in a CDM model. The ESD protection circuit includes two stages of discharging circuits that are coupled to an IO pin and the internal circuit, a first power clamp circuit, and a second power clamp circuit. The first power clamp circuit is electrically connected to a power rail and a ground rail to discharge a part of a current to the ground, and the second power clamp circuit is electrically connected to a second-stage discharging circuit and the ground rail, so that the other part of the current is discharged to the ground through the second power clamp circuit.

  • Patent number: 7714561
    Abstract: A driver for a DC-to-DC converter that may utilize a flyback or buck-boost converter circuit. The driver includes a driver circuit and an interface circuit. The interface circuit has a sensor sensing an input voltage from a DC supply and generating a sensor signal to a driver selector. The driver selector compares the sensor signal to a comparison voltage to determine the type of converter circuit and then transmits a selector signal to a driver circuit where it is used to control one or more of the components of the driver circuit, such as the logic circuit which is used for driving the converter to regulate the converter output. The sensor includes a sense resistor along with a current-sense amplifier, which is adapted for connection to a high side or a low side of a power supply while still producing a substantially equivalent output voltage or sensor signal.
