MULTI VOLTAGE-DOMAIN ELECTRO STATIC DISCHARGE (ESD) POWER CLAMP

For example, a multi voltage-domain Electro Static Discharge (ESD) power clamp may include a plurality of pins; and an ESD array including a cascaded plurality of ESD power clamps. For example, the ESD array may include a plurality of ESD array portions configured to protect a respective plurality of voltage domains from ESD. For example, the ESD array may be configured to connect the plurality of ESD array portions between a respective plurality of pin pairs from the plurality of pins. For example, an ESD array portion corresponding to a voltage domain may include one or more ESD power clamps of the cascaded plurality of ESD power clamps. For example, the ESD array portion may be configured to protect a voltage range of the voltage domain.
