Abstract
A power management circuit receives power from a host and a backup power supply in parallel and uses power from at least one of the host and the backup power supply to operate voltage regulators for a memory system. An enable signal is generated based on whether or not the voltage regulators are powered. The enable signal can be used to keep the backup power supply on while the memory system is in operation. In response to absence of power from the host, the circuit generates an interrupt signal causing the memory system to shut down safely without data loss.
