1. integrated circuit (IC) apparatus with ultra low power timer comprises:

  • Voltage ratio with input, output and first Enable Pin and logic module, wherein, when described voltage ratio and logic module on input, draw the predetermined current value when being enabled, output is in first logic level when the voltage on input is less than or equal to reference voltage, and when the voltage on input during greater than reference voltage output in second logic level;

    The outside of integrated circuit (IC) apparatus connects, and wherein, this outside connects the digital output end that is coupled to integrated circuit (IC) apparatus and described voltage ratio and on the input of logic module;

    AndThe timing capacitor that is connected coupling with this outside, the digital output end of described integrated circuit (IC) apparatus is to this timing capacitor charging thus, and described voltage ratio and the input of logic module this timing capacitor is discharged.
