HT672A Overview
The HT672A is an RF transponder IC with 13.56MHz RF carrier, which provides a low cost battery less transponder solution when bined with an external inductor. The inductor and internal capacitor form an LC tank which induce voltage from the radiated 13.56MHz carrier signal generated from the reader antenna. HT672A has a built-in low power RC oscillator which is activated if the induced carrier field strength is high...
