Abstract

A switching regulator is disclosed that includes a driver having a driver-wake circuit configured to report its readiness for operation during a startup period. The driver-wake circuit can operate during startup by temporarily drawing power from the controller's power supply until the driver's power supply has reached a level sufficient to power the driver-wake circuit. The driver-wake circuit is configured to communicate the status of the driver's power supply during startup over a pin typically used to communicate temperature. Thus, the disclosed driver can communicate status during startup without needing extra pins, and because the circuitry is automatically disconnected after startup, very little additional power is consumed.
