A thermal protection circuit integrated in a power management chip is proposed. The circuit is simulated using 0.6 μm BiCMOS process parameters and compared with the previously proposed thermal protection circuit. The results show that the circuit has the characteristics of high accuracy of the turn-off and turn-on threshold points, high temperature sensitivity, ultra-low quiescent current and low power consumption.
