Abstract:
    A circuit and method for controlling a MOSFET based switch that includes two back-to-back FET to block current flow in the OFF state irrespective of the polarity of the voltage differential across the switch. The MOSFET based switch further has a built-in current limit function by sensing the current flow through one of the two MOSFET switches. Furthermore, the bilateral current-limited switch further includes circuitry required for controlling both P type and N type FET in either common drain or common source configuration.
