Programming power management circuits in a system

A method, comprising:

• activating a first switching circuit to isolate a bus from a controller and to couple the bus with a second switching circuit;
• activating, based on activating the first switching circuit, the second switching circuit to isolate a set of one or more power management circuits from the controller and to couple the set of one or more power management circuits with the first switching circuit, wherein activating the second switching circuit isolates the set of one or more power management circuits from a second bus coupled with the controller and the second switching circuit;
• and
• programming the set of one or more power management circuits using signals communicated via the bus based on activating the first switching circuit and the second switching circuit.

A method, comprising:

• activating a first switching circuit to isolate a bus from a controller and to couple the bus with a second switching circuit;
• activating, based on activating the first switching circuit, the second switching circuit to isolate a set of one or more power management circuits from the controller and to couple the set of one or more power management circuits with the first switching circuit;
• programming the set of one or more power management circuits using signals communicated via the bus based on activating the first switching circuit and the second switching circuit;
• activating, based on determining that the set of one or more power management circuits has been successfully programmed, the first switching circuit to isolate the set of one or more power management circuits from the bus and to couple the bus with the controller;
• and
• activating, based on determining that the set of one or more power management circuits has been successfully programmed, the second switching circuit to isolate the set of one or more power management circuits from the first switching circuit and to couple the second switching circuit with the controller.

A system, comprising:

• a memory system;
• and
• a programming device coupled with the memory system and configured to cause the memory system to:
• activate a first switching circuit to isolate a bus from a controller and to couple the bus with a second switching circuit;
• activate, based on activating the first switching circuit, the second switching circuit to isolate a set of one or more power management circuits from the controller and to couple the set of one or more power management circuits with the first switching circuit, wherein activating the second switching circuit isolates the set of one or more power management circuits from a second bus coupled with the controller and the second switching circuit;
• and
• program the set of one or more power management circuits using signals communicated from the programming device to the set of one or more power management circuits via the bus based on activating the first switching circuit and the second switching circuit.
