The extension structure is coupled to and extends between the base structure and the connector head structure. The connector head structure includes a bore-hole that vertically extends into the connector head structure toward the base structure. The bore-hole is configured to receive a fastener for coupling the power connector to an electrical interface of a device. The connector head structure has a mechanical engagement feature configured to mechanically engage with a torque stabilization tool during a fastening of the fastener to the connector head structure in order to prevent a torque applied by the fastening of the fastener from being transferred to the extension structure.

The control signal generation module may be configured to, in a first mode of operation, generate an internal control signal for controlling the power stage. The routing network may be configured to, in the first mode of operation, apply the internal control signal to a control node of the power stage. The routing network may be configured to, in a second mode of operation, electrically connect said control node to an input pin of the voltage regulator module such that the power stage is controllable by an external control signal applied to said input pin. Thus, in the second mode of operation, it becomes possible to control the power stage directly via the external control signal and use this power stage e.g. as a single phase of a multi-phase power converter.

Abstract

The disclosure is directed to the use of an externally-supplied control current to control the adjustment of an internal supply voltage generated via voltage regulator circuitry, which may be identified with an integrated circuit (IC) chip. The configuration of the voltage regulator circuitry functions to establish a linear relationship between the control current and the internal voltage supply. This configuration enables setting the control current to a predetermined value, causing the supply voltage to deviate in a predictable and controllable manner, and thus facilitating verification of the IC chip's internal voltage supply test circuitry. Furthermore, because the control current used for this purpose is relatively small (e.g. on the order of microamps), existing on chip test architecture, which may accommodate such low level currents, may be re-used for the selective routing of the control current for such IC testing.

Abstract

The described techniques address issues associated with hybrid current or magnetic field sensors used to detect both low- and high-frequency magnetic field components. The hybrid sensor implements a DC component rejection path in the high-frequency magnetic field component path. Both digital and analog implementations are provided, each functioning to generate a DC component cancellation signal to at least partially cancel a DC component of a current signal generated via the high-frequency magnetic field component path. The hybrid sensor provides a high-bandwidth, high-accuracy, and low DC offset hybrid current solution that also eliminates the need for DC decoupling capacitors in the high-frequency path. A modification is also described for implementing a Sigma-Delta (ΣΔ) quantization noise reduction path to reduce the quantization noise and to improve accuracy.

The turn-on current path includes a resistor and a Zener diode connected in series, with an anode of the Zener diode connected to the control terminal and a cathode of the Zener diode connected to the resistor. The turn-on current path is configured to provide an on-current to increase the control voltage above a switching threshold. While the transistor is turned on, the Zener diode is configured to limit the control voltage to a voltage level limit that is less than the maximum rated limit.
