Power management integrated circuit load switch driver with dynamic biasing

A system comprising:

• an interface;
• a power management integrated circuit (PMIC), the PMIC powered by voltages supplied over the interface and including a load switch driver;
• and
• one or more memory devices coupled to the load switch driver of the PMIC via at least one switch, the load switch driver configured to monitor a drain-source voltage of the switch and lower a frequency of an operation frequency generator to a second frequency in response to detecting a collapse of the drain-source voltage.

A method comprising:

• supplying a gate voltage to a gate of a switch at a first frequency;
• monitoring a drain-source voltage of the switch;
• determining that the drain-source voltage of the switch has collapsed;
• and
• supplying the gate voltage to the gate of the switch at a second frequency in response to determining that the drain-source voltage has collapsed.
