The Si6924EDQ is a dual n-channel MOSFET with ESD protection and gate over-voltage protection circuitry incorporated into the MOSFET. The device is designed for use in Lithium Ion battery pack circuits. The common-drain contsruction takes advantage of the typical battery pack topology, allowing a further reduction of the device's on-resistance. The 2-stage input protection circuit is a unique design, consisting of two stages of back-to-back zener diodes separated by a resistor. The first stage diode is designed to absorb most of the ESD energy. The second stage diode is
