Semiconductor Device with Overcurrent Protection

摘要

A semiconductor device with an over-current detection feature is disclosed. According to an example of the invention the device includes: a semiconductor chip including a load current path that conducts a load current in response to an input signal activating the load current flow. A current sensor arrangement provides a measurement signal representing the load current. An evaluation circuit is configured to compare the measurement signal with a first threshold and to signal an over-current when the measurement signal exceeds the first threshold after a delay time period starting from the activation of the load current flow has elapsed.
