NORMALLY-OFF COMPOSITE POWER DEVICE AND MONOLITHIC INTEGRATED NORMALLY-OFF COMPOSITE POWER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a normally-off (enhancement-type) composite power device including an electrostatic discharge (ESD) protection clamp.;SOLUTION: A normally-off composite power device 200 includes: a normally-on (depletion-type) power transistor 210 forming a composite drain 202 of a normally-off composite device; and a normally-off low-voltage (LV) transistor 220 cascode-connected with the normally-on power transistor. A composite source 204 and a composite gate 206 of the normally-off composite power device are formed by the normally-off low-voltage transistor. The normally-off composite power device also includes an ESD protection clamp 230 connected between the composite source and the composite gate. The ESD protection clamp is configured to protect the normally-off composite power device from ESD.;COPYRIGHT: (C)2015,JPO&INPIT
