Current sensing switch circuitry with compensation

Abstract

An apparatus such as a switch circuit providing current monitoring as discussed herein may include a first switch fabricated via first semiconductor technology, a second switch fabricated via second semiconductor technology, and current monitor circuitry. The current monitor circuitry may include the second switch. The current monitor circuitry can be configured to provide mirroring of a magnitude of second current through the second switch with respect to a magnitude of first current through the first switch. The apparatus as discussed herein may further include a signal converter operative to convert a first control signal controlling the first switch into a second control signal operative to control the second switch. Additionally, the apparatus as discussed herein may include a gate drive voltage compensation circuit and/or a temperature compensation circuit to provide compensation and a more accurate output signal indicating a magnitude of the first current through the first switch.
