Introduction

ISL6207HRZ is a high-current, high-frequency gate driver designed for driving power FETs, MOSFETs, IGBTs, and any other high-side and low-side FETs. The driver is capable of supplying peak output current up to 3.2A, and it is designed to handle high-side operating voltages up to 700V and low-side operating voltages up to 100V. In addition, the driver offers fast switching speeds, high switching frequency of up to 100kHz, and very low quiescent and operating current. As such, the ISL6207HRZ gate driver is highly suitable for use in motor control, power conversion, consumer electronics, HVAC, and automotive applications.

Description

The ISL6207HRZ driver is a dual-channel gate driver with two input pins, two output pins, and a control pin. The two input pins control the logic supply voltage, while the output pins provide the gate source and sink. The control pin is used to control the logic state of the output. The driver is powered by a single voltage source, and it offers a wide range of operating voltages, from 0.3V to 700V. The ISL6207HRZ is designed for high-frequency switching applications. It is capable of switching frequencies up to 100kHz, making it ideal for applications such as motor control, power conversion, consumer electronics, HVAC, and automotive applications.The driver also features a low quiescent and operating current, making it highly energy efficient. The driver is also constructed with an integrated spread-spectrum technology which helps to reduce the amount of EMI generated.

Working Principle

The working principle of the ISL6207HRZ gate driver is based on a two-stage current driver architecture. This two-stage architecture consists of a high-current control stage and a high-speed control stage. The high-current control stage consists of an opto-isolator driver IC, which is used to control the voltage level at the gate of the FET or IGBT. The output of the opto-isolator is then amplified by a power MOSFET with an output voltage level of up to 700V. The high-speed control stage is composed of an adjustable hysteresis stage, which is used to control the rise and fall time of the gate voltage. The opto-isolator driver is capable of supplying peak output currents of up to 3.2A, allowing for faster switching speeds, improved response time and higher efficiency. The adjustable hysteresis stage is designed for fine tuning the switching times of the signal, allowing for optimized on-off switching times and improved signal fidelity.

Applications

The ISL6207HRZ gate driver is highly suitable for applications such as motor control, power conversion, consumer electronics, HVAC, and automotive applications. It is capable of providing high-current drive levels, fast switching speeds, high switching frequency of up to 100kHz, and very low quiescent and operating current.In motor control applications, the driver can be used to drive the gates of power FETs and IGBTs for higher efficiency and improved performance.
