Hello Shine,

Thank you for the query.

The load switch is used to switch the main 3.3V to 3.3V_SYS used for the SoC and the attached devices.

The Load switch also performs the voltage sequencing.

With the current architecture this load switch is required for sequencing.

Can you help me understand the use case.

Regards,

Sreenivasa

Hello Shine,

Please refer below that i copied from the above note.

The load switch is used to switch the main 3.3V to 3.3V_SYS used for the SoC and the attached devices.

The Load switch control comes from the PMIC and the PMIC sequences the other supply rails used by AM62A.
