  • MULTI-MODE HIGH VOLTAGE CIRCUIT
    Publication number: 20210064070
    Abstract: In an example, a circuit includes a first power switch device coupled between a voltage input and an output terminal, the first power switch device having a control input. A voltage divider circuit includes a first resistor and a second resistor. The first resistor is coupled between the voltage input and a sense node between the first resistor and the second resistor. The second resistor has a first terminal coupled to the sense node and a second terminal. A second switch device is coupled between the second terminal of the second resistor and an electrical ground terminal. A voltage clamp is coupled between the sense node and the electrical ground terminal.
    Type: Application

  • Resistor divider with improved resistor matching
    Patent number: 10840241
    Abstract: Described examples include a semiconductor device having a resistor. The resistor includes a first terminal and a second terminal. The resistor also includes a first resistive element over an insulating layer over a substrate having a first end coupled to the first terminal of the resistor and a second end coupled to the second terminal of the resistor; and a parallel second resistive element over the insulating layer over the substrate having a first end coupled to the first terminal of the resistor and a second end coupled to the second terminal of the resistor. The resistor may also be coupled in series with another resistor.
