The ISL6613CR is a high density, low-noise, low-power analog earth gate driver designed specifically for data communication applications, such as micro and Ethernet switches and routers. It is designed to drive high current pulses into and out of the ground connection in order to minimize common-mode noise, reduce power losses and maximize signal integrity. The ISL6613CR eliminates the need for additional external transistors or FETs, thereby significantly reducing the required board space, cost and complexity. This makes it an ideal solution for many data communications applications.

The ISL6613CR features a wide input voltage range from 4.5V to 15V, a wide range of output functions and impedance, and a gate-drive current of up to 18A. The device features an adjustable dead time of up to 25ns, allowing designers to maximize common-mode noise reduction. Additionally, the ISL6613CR can be controlled via its I2C interface for full independent control of each gate for complex switching applications.

The working principle of the ISL6613CR is simple. When a voltage is applied to one of its inputs, it drives the gate of an external N-Channel MOSFET high. This allows current to flow, either into or out of the ground connection, thereby minimizing common-mode noise. Furthermore, the adjustable dead-time allows designers to fine-tune the common-mode noise minimization by delaying the gate drive of the opposite-polarity FET.

The ISL6613CR is an ideal gate driver solution for high-current, low-noise data communication applications. Its low power consumption and integrated features make it an attractive choice for reducing board space and complexity, while maximizing signal integrity. Furthermore, its I2C control interface provides the flexibility to configure the outputs for complex switching applications.
