Abstract
This paper presents a method of merging the threshold voltage of zero temperature coefficients and comparative function into a single circuit. With application to undervoltage lockout circuit, it can reduce temperature sensitivity of threshold voltage and improve accuracy of threshold. Meanwhile, this undervoltage protection circuit realizes hysteretic threshold by a feedback control method so as to overcome disadvantage of poor interference rejection capability of single threshold. This undervoltage lockout circuit can be applied to DC-DC converter.
