Abstract:
A transceiver is connectable to a cable with at least three wires. The transceiver may include a controlled output stage including a high-side leg, having two P-type transistors coupled in series and having a common current terminal, coupled between an output pin and a positive supply pin. The P-type transistors have body regions coupled to the common current terminal of the high-side leg. A low-side leg, includes two N-type transistors coupled in series and having a common current terminal, coupled between the output pin and a negative supply pin. The N-type transistors have body regions coupled to the common current terminal of the low-side leg. The protection circuit also includes a voltage clamper coupled between the common current terminals.
