Hybrid circuit for circuit protection and switching
摘要：
A hybrid circuit (42) for use with communications transceivers. The hybrid circuit (42) combines the function of an ESD protection circuit (12) with the function of a TX/RX switch (10). The input node of the hybrid circuit (42) is connecting between the source of an ESD event (60) and a device to be protected (44). The hybrid circuit (42) includes an ESD protection element (50), which is triggered by a triggering transistor (52). The gate of the triggering transistor (52) is connected to a driver (54) for turning the triggering transistor (52) on during transmission and for turning the triggering transistor (52) off during reception.
