The ISL6613CRZ-T is an integrated circuit integrated within the PMIC - Gate Driver family. It is designed to be used primarily for driving medium voltage FETs and IGBTs, providing a high level of integration with a wide range of features.

This device comes with an adjustable front gate drivers and a rear driver stage offering an output voltage range from 5V to 50V. It includes a power switch, an RC filter, a synchronous gate drive optocoupler, a gate driver, and an over-voltage protection circuit.

The main application of the ISL6613CRZ-T is to be used in DC-DC converters, including buck, boost and LLC, as well as in switched-mode power supplies. It can also be used in many other applications, such as UPS systems, solar inverters and industrial motor control.

The working principle of the ISL6613CRZ-T is based on the driver having an adjustable gate voltage. The gate voltage is generated through an internal charge pump circuit, and the maximum output voltage is defined by an external resistor. The gate voltage applied to MOSFETs and IGBTs will be determined by the user-selected external resistor, and the maximum gate voltage is dependent on the input supply voltage. The current sourced and sunk by the gate driver is also adjustable to provide optimum FET performance.

In addition, the ISL6613CRZ-T features short circuit protection to protect against short-circuits, over-temperature protection to prevent thermal runaway, and over-current protection to protect against overloads. The device also includes a weak pull-down circuit to prevent over-voltage during turn-off.

The ISL6613CRZ-T is an effective and efficient device that provides a wide range of features. It integrates power switches, filters, gate voltage generator, and protection circuits, enabling an extensive range of applications. The adjustable front gate driver and rear driver stage also provide a wide output voltage range, making it suitable for a range of applications requiring different supply voltages.
