Abstract: A power module package may comprise a first metal oxide semiconductor field effect transistor (MOSFET), wherein the first MOSFET is configured to operate in a linear mode of operation when the first MOSFET is ON; a second MOSFET, wherein the second MOSFET is configured to operate in a non-linear mode of operation when the second MOSFET is ON, and wherein the first MOSFET and the second MOSFET are arranged in parallel; and a third MOSFET, wherein the third MOSFET is arranged to perform one or more sensing operations. The first MOSFET, the second MOSFET, and the third MOSFET may be arranged within a molding compound of the power module package.

Abstract: According to an embodiment, a current monitoring circuit includes a signal shaping unit configured to receive a current sense signal and provide a modified current signal; a filter configured to receive the modified current signal and to provide a respective filtered signal; a comparator configured to receive the filtered signal and a threshold value and to indicate when the filtered signal exceeds the threshold value. The signal shaping unit is configured to calculate a level of the modified current signal from a corresponding level of the current sense signal in accordance with non-linear function.

Abstract: In accordance with an embodiment, a circuit for driving an electronic switch includes a control circuit configured to trigger a switch-on and a switch-off of the electronic switch in accordance with an input signal, wherein the control circuit is further configured to trigger the switch-off of the electronic switch in response to an under-voltage signal signaling an under-voltage state; and an under-voltage detection circuit configured to signal the under-voltage state when a supply voltage received at a supply node is below an under-voltage threshold value, wherein the under-voltage threshold value depends on a load current passing through the electronic switch.
