    Abstract: Various embodiments comprise a protective circuit to connect at least two voltage rails to each other upon detection of the loss of the supply voltage that provides input power to the voltage regulators. The protective circuit may cause the two outputs of the voltage regulators to be connected to each other through a resistor when such a loss occurs. This in turn may prevent possible circuit damage in the load by preventing the higher output voltage from dropping below the lower output voltage if the capacitors on the outputs of the voltage regulators discharge at different rates. Such a reverse-voltage condition might otherwise cause damage in the load circuitry.

    Abstract: Disclosed herein are systems and methods for self-isolation of power-management integrated circuits (PMICs) of memory modules under and in response to fault conditions. In an embodiment, a PMIC is operably engaged with a memory module that is operably engaged with a platform. The memory module includes a non-volatile-memory block having a power supply controlled by the PMIC. The PMIC has a critical-fault signal pin that can be asserted to shut down the platform. The PMIC determines whether at least one critical fault occurred during a prior cycle, and also determines whether a critical fault occurs during a bootup sequence during a current cycle. Based on determining that a prior-cycle critical fault occurred and that a critical fault occurs during the bootup sequence, the PMIC sets a critical-fault indicator corresponding to the current critical fault; powers down the power supply; and does not assert the critical-fault signal pin.
