Abstract

An integrated current detector designed to protect high voltage LDMOS power switches is presented in this paper. The proposed detector monitors the current of power switches by a mirrored ratio current. Power switches can be automatically turned off once the mirrored current exceeds the predetermined triggered value and thereby protect power switches from being damages. The response time of current detector determines the maximum operation frequency of the driving signal to the power switch. Both simulated and measurement results show that the designed current detector with an integrated LDMOS switch can work higher than 1 MHz switching frequency with maximum 1A current driving capability.
