摘要： An electrostatic discharge (ESD) protection circuit (40) is coupled across input-output (I/O) pads (21) and common terminals (24) of a core circuit (22) to protect it from ESD events. The circuit (40) comprises, a unidirectional ESD clamp (23) and two or more floating diodes (42, 44) arranged in parallel opposed configuration in series with the ESD clamp (23), the combination coupled between the I/O pads (21) and the reference terminals (24). In a preferred arrangement, the two strings of opposed parallel coupled diodes (42, 44) are used with different numbers of diodes in each string. These diodes (42, 44) operate in forward conduction (43, 45), so the energy dissipated therein during an ESD event is much reduced compared to a reverse biased diode and they can have smaller area. Signal clipping at the I/O pad (21) is reduced, less power is dissipated and less chip area is utilized.

摘要： An ESD protection circuit (20) includes an ESD device (24) and an isolation diode element (30). The ESD device includes a drain-source junction isolated ESD transistor (26,28). The isolation diode element is coupled in series with the ESD device and configured for providing ESD protection to a transistor device (22) needing ESD protection. Responsive to −Vgs conditions on a gate of the protected transistor device, the series coupled isolation diode element prevents a forward biasing of the drain-source junction of the ESD transistor prior to a breakdown condition of the isolation diode element. In addition, responsive to an ESD event sufficient to cause damage to the protected transistor device, the series coupled isolation diode element permits an occurrence of the breakdown condition. Furthermore, the ESD protection circuit can operate in both (i) a polarity of normal operation of the protected device and (ii) an opposite polarity other than in normal operation of the protected device.

摘要： An electrostatic discharge (ESD) protection circuit (20) includes an active load circuit (22) connected to a Laterally Diffused Metal Oxide Semiconductor (LDMOS) transistor (21) having a Lightly Doped Drain (LDD). The active load circuit includes a current limiting circuit (26) and a load transistor (27). The ESD protection circuit (20) operates to protect a power transistor (16) from damage due to an electrostatic charge. During an ESD event, the LDMOS transistor (21) enters avalanche breakdown after the voltage of the electrostatic charge exceeds the breakdown voltage of the LDMOS transistor (21). The ESD protection circuit (20) provides a low resistance path during an ESD event to dissipate the electrostatic charge.
