Abstract
One example discloses a voltage limiting device, including: a first I/O port; a second I/O port; a voltage limiter, coupled to the first and second I/O ports, and configured to shunt a voltage received on the first and/or second I/O ports having an absolute value greater than a voltage limit; wherein the voltage limiter includes a first portion and a second portion; wherein the first portion includes a first current shunt coupled between the first I/O port and a mid-net, and a second current shunt coupled between the second I/O port and the mid-net; and wherein the second portion includes a third current shunt having one end coupled to the mid-net and another end coupled to a ground.
