Abstract
A switching circuit is described which includes an output switch having a drive terminal and a power supply terminal. Driver circuitry provides a drive signal to the output switch. Isolation circuitry provides DC isolation between the driver circuitry and the output switch. Transient control circuitry controls the drive terminal, thereby keeping the output switch off during stabilization of a supply voltage at the power supply terminal.
