ENABLE AND DISABLE COMPARATOR VOLTAGE REFERENCE

摘要

PURPOSE: An enabling/disabling device of comparator reference voltage is provided to reduce a leakage current by separating reference input of a comparator from a power source. CONSTITUTION: A comparator(105) receives reference voltage from reference input. The comparator receives mobile device accessory device information. The comparator compares the mobile device accessory device information with the reference voltage. A switch(110) receives connection information from control input. The switch separates the reference input of the comparator from power source voltage using the connection information.
