Abstract
The present disclosure relates to an apparatus and method for driving a switch, such as a power switch. A driver comprises a voltage sensor to sense a drive voltage, and an electrical source to provide a drive signal having a drive value. The driver is adapted to adjust the drive value based on the drive voltage to limit a switch-current flowing through the switch.
