Abstract

A transistor semiconductor die includes a first current terminal, a second current terminal, and a control terminal. A semiconductor structure is between the first current terminal, the second current terminal, and the control terminal and configured such that a resistance between the first current terminal and the second current terminal is based on a control signal provided at the control terminal. Short circuit protection circuitry is coupled between the control terminal and the second current terminal. In a normal mode of operation, the short circuit protection circuitry is configured to provide a voltage drop that is greater than a voltage of the control signal. In a short circuit protection mode of operation, the short circuit protection circuitry is configured to provide a voltage drop that is less than a voltage of the control signal.
