Abstract: A power down signal generator generates a power down signal. The power down signal generator includes a detection transistor, a resistor coupled in series with the detection transistor, and a compensation transistor coupled in parallel to the resistor. The detection transistor receives a first supply voltage in a first voltage domain and a current. A control voltage is generated across the resistor based on a first part of the current. The compensation transistor receives a bias voltage derived from a second supply voltage in a second voltage domain and sinks, based on the bias voltage, a second part of the current to maintain the control voltage within a predefined range. The generation of the power down signal is controlled based on the first supply voltage and the control voltage.

Abstract: Embodiments of a differential driver circuit and a method for controlling a differential driver circuit are described. Embodiments of a differential driver circuit may include a current steering circuit configured to determine a current direction through differential output terminals of the differential driver circuit, two resistors connected between the differential output terminals of the differential driver circuit and first and second semiconductor circuits connected to a point between the two resistors. The first and second semiconductor circuits are of different types. The source terminals of the first and second semiconductor circuits are connected to the point between the two resistors.
