A Low Power consumption CMOS Thermal-shutdown Circuit with Hysteresis
Guoping Jiang · Modern Electronics Technique · 2008
Using 0.5 μm CMOS technology,this paper presents a thermal-shutdown circuit with hysteresis.This circuit is simulated by using the tool of Cadence Spectre.It shows the circuit has an excellent ability of power rejection.Above the 3.5 voltage of power,the temperature of thermal-shutdown is constant.The plus temperature is about 155 ℃ and the minus one is about 105 ℃.Meanwhile,the power consumption is little.It is 0.25 mW under the power of 5 V.Because of the better performances of high stability and low power consumption,this thermal-shutdown circuit can be widely used in many kinds of integrated circuits.
