Detector of fast variation in the supply of integrated circuits

摘要: Some integrated circuits need to be protected against malfunctioning due the variations in supply voltage Vcc. A detector of fast is placed circuit interrupt or modify all a part working general event occurrence variation The includes capacitor, current limiter, charging circuit, and detection transistor. limiter transistor mounted as diode. uses charge capacitor through limiter. relatively stable applied gate transistor, which has threshold Vtp. source connected If Vcc varies suddenly, made conductive. assembly difference between Vtn Vtp
