Reverse recovery behavior is a useful tool for monitoring lifetime variations in the body diode of power MOSFETs. However, correct interpretation of the laterally diffused MOSFET (LDMOS) reverse recovery is challenging and requires special attention. This is due to the fact that the stored charges in the LDMOS drift region can flow from two different directions with each having different lifetime values. By studying the effects of diode reverse bias and gate voltage on the current flow…

A new 1200 V HVIC with high side edge trigger in order to solve the latch on failure by the negative VS surge

The experimental results show the latch on failure no longer occurs on the new 1200 V HVIC because it doesn't overlap the VS recovery period and the RESET pulse period.
