The EL7243CM is an integrated gate driver designed for high-side, high voltage switching applications. It integrates two high-current half-bridge MOSFET drivers, and is designed for use with high-side, low-on-resistance power MOSFETs in a variety of high-voltage, high-current switching applications, including AC/DC converters, inverters, motor control, and HVAC.

The device is capable of sourcing and sinking large amounts of current to ensure fast, accurate switching of both MOSFETs regardless of their type. It also integrates several safety and protection features to protect against short circuits and over voltages. Additionally, it includes an adjustable over-current sense comparator and a fault indicator with an adjustable threshold, as well as rich diagnostics.

The EL7243CM is an ideal device for applications requiring fast switching, low on-resistance, and high-current handling capability. It is suitable for direct interface to high-power dual-MOSFET half-bridges and can switch voltages from 5V to 50V, at peak currents up to 9A. It supports a wide variety of switching frequencies, from 100KHz to 600KHz, and features an integrated current sense comparator with adjustable threshold to monitor and protect against over-current conditions. The device is also well-suited for remote control applications, with an adjustable maximum switching frequency of 1MHz.

The EL7243CM gate driver is designed using a low-power CMOS process that ensures low power dissipation and high speed. The device also contains an internal level shifter that allows it to drive the gate of the high-side MOSFET at a voltage greater than the supply voltage of the device. This level shifter works on the principle of charge transfer and enables the device to perform its high-side switching. The device offers inbuilt short circuit and overvoltage protection and fault indication, making it suitable for high-reliability applications. The device also includes low-power sleep mode to ensure low power dissipation in the event of faults or in idle or standby conditions.

In summary, the EL7243CM is an ideal device for switching applications requiring fast switching and high-current handling capability. It has integrated features that improve reliability and safety, and its low power-dissipation, sleep mode, and high switching frequency makes it an ideal choice for high-efficiency, reliable applications.
