Abstract
This disclosure is directed to circuits and techniques for configuring a driver circuit for a power switch when entering a fail-safe state. The driver circuit includes a volatile memory connected to a plurality of independent power supplies, the volatile memory configured to store a fail-safe configuration for the driver circuit. The driver circuit includes driver logic connected to the volatile memory that is configured to determine to enter a fail-safe state and, in response to determining to enter the fail-safe state, configure the driver circuit or a power switch according to the fail-safe configuration stored in the volatile memory.
