1. A system for an inverter including a first set of switches and a second set of switches to control an operation of an electric motor, the system comprising:
a first integrated circuit configured to:
provide power to the first set of switches using a first high voltage supply and a first low voltage supply, the first high voltage supply and the first low voltage supply being connected to the first integrated circuit, and
selectively control the first set of switches and the second set of switches; and
a second integrated circuit configured to:
provide power to the second set of switches using a second high voltage supply and a second low voltage supply, the second high voltage supply and the second low voltage supply being connected to the second integrated circuit, and
in response to a fault detected in the first integrated circuit, selectively control the first set of switches and the second set of switches, and
in response to at least one voltage value corresponding to a voltage of the first set of switches being outside of a threshold, performing a safe state operation.
