摘要：
This paper, we present a new integrated structure which can protect insulated gate power devices (IGBT, VDMOS, EST,...) from short-circuit operating mode. This structure is built with an anode voltage sensor, a delay LDMOS transistor, a LDMOS transistor allowing the power device gate unload and a Zener diode. It is notable that this protection structure is fully compatible with it power-device technological process. The operating mode and the first optimization of the protection structure are presented. For this, IGBT is used as test device. 2D simulations are performed with ISE TCAD. First experimental results of the anode voltage sensor are given and compared with simulation results.
