Abstract
A driver includes first and second switches. A first transistor has a first control input and first and second current terminals. A resistor couples between a voltage supply terminal and the first control input. A configurable voltage clamp circuit has a voltage clamp control input and a voltage clamp circuit output coupled to the first control input. A second transistor has a second control input and third and fourth current terminals. A logic circuit includes a comparator having a comparator output. The logic circuit couples to the voltage supply terminal and the voltage clamp control input. The logic circuit is configured to configure the voltage clamp circuit for a first clamp voltage at the voltage clamp circuit output responsive to the first switch being turned ON and for a second clamp voltage at the voltage clamp circuit output based on a signal at the comparator output.
